Run rclone config to setup. See rclone config docs (http://rclone.org/docs/) for more
details.
rclone config
Install from source
Make sure you have at least Go (https://golang.org/) 1.5 installed. Make sure your GOPATH
is set, then:
go get -u -v github.com/ncw/rclone
and this will build the binary in $GOPATH/bin. If you have built rclone before then you
will want to update its dependencies first with this
go get -u -v github.com/ncw/rclone/...
Installation with Ansible
This can be done with Stefan Weichinger's ansible role
(https://github.com/stefangweichinger/ansible-rclone).
Instructions
1. git clone https://github.com/stefangweichinger/ansible-rclone.git into your local
roles-directory
2. add the role to the hosts you want rclone installed to:
- hosts: rclone-hosts
roles:
- rclone
Installation with snap
Quickstart
• install Snapd on your distro using the instructions below
• sudo snap install rclone --classic
• Run rclone config to setup. See rclone config docs (http://rclone.org/docs/) for more
details.
See below for how to install snapd if it isn't already installed
Arch
sudo pacman -S snapd
enable the snapd systemd service:
sudo systemctl enable --now snapd.socket
Debian / Ubuntu
sudo apt install snapd
Fedora
sudo dnf copr enable zyga/snapcore
sudo dnf install snapd
enable the snapd systemd service:
sudo systemctl enable --now snapd.service
SELinux support is in beta, so currently:
sudo setenforce 0
to persist, edit /etc/selinux/config to set SELINUX=permissive and reboot.
Gentoo
Install the gentoo-snappy overlay (https://github.com/zyga/gentoo-snappy).
OpenEmbedded/Yocto
Install the snap meta layer (https://github.com/morphis/meta-
snappy/blob/master/README.md).
openSUSE
sudo zypper addrepo http://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_42.2/ snappy
sudo zypper install snapd
OpenWrt
Enable the snap-openwrt feed.
Configure
First you'll need to configure rclone. As the object storage systems have quite
complicated authentication these are kept in a config file. (See the --config entry for
how to find the config file and choose its location.)
The easiest way to make the config is to run rclone with the config option:
rclone config
See the following for detailed instructions for
• Google drive (http://rclone.org/drive/)
• Amazon S3 (http://rclone.org/s3/)
• Swift / Rackspace Cloudfiles / Memset Memstore (http://rclone.org/swift/)
• Dropbox (http://rclone.org/dropbox/)
• Google Cloud Storage (http://rclone.org/googlecloudstorage/)
• Local filesystem (http://rclone.org/local/)
• Amazon Drive (http://rclone.org/amazonclouddrive/)
• Backblaze B2 (http://rclone.org/b2/)
• Hubic (http://rclone.org/hubic/)
• Microsoft One Drive (http://rclone.org/onedrive/)
• Yandex Disk (http://rclone.org/yandex/)
• SFTP (http://rclone.org/sftp/)
• Crypt (http://rclone.org/crypt/) - to encrypt other remotes
Usage
Rclone syncs a directory tree from one storage system to another.
Its syntax is like this
Syntax: [options] subcommand <parameters> <parameters...>
Source and destination paths are specified by the name you gave the storage system in the
config file then the sub path, eg "drive:myfolder" to look at "myfolder" in Google drive.
You can define as many storage paths as you like in the config file.
Subcommands
rclone uses a system of subcommands. For example
rclone ls remote:path # lists a re
rclone copy /local/path remote:path # copies /local/path to the remote
rclone sync /local/path remote:path # syncs /local/path to the remote
rclone config
Enter an interactive configuration session.
Synopsis
Enter an interactive configuration session.
rclone config
rclone copy
Copy files from source to dest, skipping already copied
Synopsis
Copy the source to the destination. Doesn't transfer unchanged files, testing by size and
modification time or MD5SUM. Doesn't delete files from the destination.
Note that it is always the contents of the directory that is synced, not the directory so
when source:path is a directory, it's the contents of source:path that are copied, not the
directory name and contents.
If dest:path doesn't exist, it is created and the source:path contents go there.
For example
rclone copy source:sourcepath dest:destpath
Let's say there are two files in sourcepath
sourcepath/one.txt
sourcepath/two.txt
This copies them to
destpath/one.txt
destpath/two.txt
Not to
destpath/sourcepath/one.txt
destpath/sourcepath/two.txt
If you are familiar with rsync, rclone always works as if you had written a trailing / -
meaning "copy the contents of this directory". This applies to all commands and whether
you are talking about the source or destination.
See the --no-traverse option for controlling whether rclone lists the destination
directory or not.
rclone copy source:path dest:path
rclone sync
Make source and dest identical, modifying destination only.
Synopsis
Sync the source to the destination, changing the destination only. Doesn't transfer
unchanged files, testing by size and modification time or MD5SUM. Destination is updated
to match source, including deleting files if necessary.
Important: Since this can cause data loss, test first with the --dry-run flag to see
exactly what would be copied and deleted.
Note that files in the destination won't be deleted if there were any errors at any point.
It is always the contents of the directory that is synced, not the directory so when
source:path is a directory, it's the contents of source:path that are copied, not the
directory name and contents. See extended explanation in the copy command above if
unsure.
If dest:path doesn't exist, it is created and the source:path contents go there.
rclone sync source:path dest:path
rclone move
Move files from source to dest.
Synopsis
Moves the contents of the source directory to the destination directory. Rclone will
error if the source and destination overlap and the remote does not support a server side
directory move operation.
If no filters are in use and if possible this will server side move source:path into
dest:path. After this source:path will no longer longer exist.
Otherwise for each file in source:path selected by the filters (if any) this will move it
into dest:path. If possible a server side move will be used, otherwise it will copy it
(server side if possible) into dest:path then delete the original (if no errors on copy)
in source:path.
Important: Since this can cause data loss, test first with the --dry-run flag.
rclone move source:path dest:path
rclone delete
Remove the contents of path.
Synopsis
Remove the contents of path. Unlike purge it obeys include/exclude filters so can be used
to selectively delete files.
Eg delete all files bigger than 100MBytes
Check what would be deleted first (use either)
rclone --min-size 100M lsl remote:path
rclone --dry-run --min-size 100M delete remote:path
Then delete
rclone --min-size 100M delete remote:path
That reads "delete everything with a minimum size of 100 MB", hence delete all files
bigger than 100MBytes.
rclone delete remote:path
rclone purge
Remove the path and all of its contents.
Synopsis
Remove the path and all of its contents. Note that this does not obey include/exclude
filters - everything will be removed. Use delete if you want to selectively delete files.
rclone purge remote:path
rclone mkdir
Make the path if it doesn't already exist.
Synopsis
Make the path if it doesn't already exist.
rclone mkdir remote:path
rclone rmdir
Remove the path if empty.
Synopsis
Remove the path. Note that you can't remove a path with objects in it, use purge for
that.
rclone rmdir remote:path
rclone check
Checks the files in the source and destination match.
Synopsis
Checks the files in the source and destination match. It compares sizes and hashes (MD5
or SHA1) and logs a report of files which don't match. It doesn't alter the source or
destination.
If you supply the --size-only flag, it will only compare the sizes not the hashes as well.
Use this for a quick check.
If you supply the --download flag, it will download the data from both remotes and check
them against each other on the fly. This can be useful for remotes that don't support
hashes or if you really want to check all the data.
rclone check source:path dest:path
Options
--download Check by downloading rather than with hash.
rclone ls
List all the objects in the path with size and path.
Synopsis
List all the objects in the path with size and path.
rclone ls remote:path
rclone lsd
List all directories/containers/buckets in the path.
Synopsis
List all directories/containers/buckets in the path.
rclone lsd remote:path
rclone lsl
List all the objects path with modification time, size and path.
Synopsis
List all the objects path with modification time, size and path.
rclone lsl remote:path
rclone md5sum
Produces an md5sum file for all the objects in the path.
Synopsis
Produces an md5sum file for all the objects in the path. This is in the same format as
the standard md5sum tool produces.
rclone md5sum remote:path
rclone sha1sum
Produces an sha1sum file for all the objects in the path.
Synopsis
Produces an sha1sum file for all the objects in the path. This is in the same format as
the standard sha1sum tool produces.
rclone sha1sum remote:path
rclone size
Prints the total size and number of objects in remote:path.
Synopsis
Prints the total size and number of objects in remote:path.
rclone size remote:path
rclone version
Show the version number.
Synopsis
Show the version number.
rclone version
rclone cleanup
Clean up the remote if possible
Synopsis
Clean up the remote if possible. Empty the trash or delete old file versions. Not
supported by all remotes.
rclone cleanup remote:path
rclone dedupe
Interactively find duplicate files delete/rename them.
Synopsis
By default dedup interactively finds duplicate files and offers to delete all but one or
rename them to be different. Only useful with Google Drive which can have duplicate file
names.
The dedupe command will delete all but one of any identical (same md5sum) files it finds
without confirmation. This means that for most duplicated files the dedupe command will
not be interactive. You can use --dry-run to see what would happen without doing
anything.
Here is an example run.
Before - with duplicates
$ rclone lsl drive:dupes
6048320 2016-03-05 16:23:16.798000000 one.txt

Dedupe can be run non interactively using the --dedupe-mode flag or by using an extra
parameter with the same value
• --dedupe-mode interactive - interactive as above.
• --dedupe-mode skip - removes identical files then skips anything left.
• --dedupe-mode first - removes identical files then keeps the first one.
• --dedupe-mode newest - removes identical files then keeps the newest one.
• --dedupe-mode oldest - removes identical files then keeps the oldest one.
• --dedupe-mode rename - removes identical files then renames the rest to be different.
For example to rename all the identically named photos in your Google Photos directory, do
rclone dedupe --dedupe-mode rename "drive:Google Photos"
Or
rclone dedupe rename "drive:Google Photos"
rclone dedupe [mode] remote:path
Options
--dedupe-mode string Dedupe mode interactive|skip|first|newest|oldest|rename. (default "interactive")
rclone authorize
Remote authorization.
Synopsis
Remote authorization. Used to authorize a remote or headless rclone from a machine with a
browser - use as instructed by rclone config.
rclone authorize
rclone cat
Concatenates any files and sends them to stdout.
Synopsis
rclone cat sends any files to standard output.
You can use it like this to output a single file
rclone cat remote:path/to/file
Or like this to output any file in dir or subdirectories.
rclone cat remote:path/to/dir
Or like this to output any .txt files in dir or subdirectories.
rclone --include "*.txt" cat remote:path/to/dir
Use the --head flag to print characters only at the start, --tail for the end and --offset
and --count to print a section in the middle. Note that if offset is negative it will
count from the end, so --offset -1 --count 1 is equivalent to --tail 1.
rclone cat remote:path
Options
--count int Only print N characters. (default -1)
--discard Discard the output instead of printing.
--head int Only print the first N characters.
--offset int Start printing at offset N (or from end if -ve).
--tail int Only print the last N characters.
rclone copyto
Copy files from source to dest, skipping already copied
Synopsis
If source:path is a file or directory then it copies it to a file or directory named
dest:path.
This can be used to upload single files to other than their current name. If the source
is a directory then it acts exactly like the copy command.
So
rclone copyto src dst
where src and dst are rclone paths, either remote:path or /path/to/local or C:.
This will:
if src is file
copy it to dst, overwriting an existing file if it exists
if src is directory
copy it to dst, overwriting existing files if they exist
see copy command for full details
This doesn't transfer unchanged files, testing by size and modification time or MD5SUM.
It doesn't delete files from the destination.
rclone copyto source:path dest:path
rclone cryptcheck
Cryptcheck checks the integritity of a crypted remote.
Synopsis
rclone cryptcheck checks a remote against a crypted remote. This is the equivalent of
running rclone check, but able to check the checksums of the crypted remote.
For it to work the underlying remote of the cryptedremote must support some kind of
checksum.
It works by reading the nonce from each file on the cryptedremote: and using that to
encrypt each file on the remote:. It then checks the checksum of the underlying file on
the cryptedremote: against the checksum of the file it has just encrypted.
Use it like this
rclone cryptcheck /path/to/files encryptedremote:path
You can use it like this also, but that will involve downloading all the files in
remote:path.
rclone cryptcheck remote:path encryptedremote:path
After it has run it will log the status of the encryptedremote:.
rclone cryptcheck remote:path cryptedremote:path
rclone genautocomplete
Output bash completion script for rclone.
Synopsis
Generates a bash shell autocompletion script for rclone.
This writes to /etc/bash_completion.d/rclone by default so will probably need to be run
with sudo or as root, eg
sudo rclone genautocomplete
Logout and login again to use the autocompletion scripts, or source them directly
. /etc/bash_completion
If you supply a command line argument the script will be written there.
rclone genautocomplete [output_file]
rclone gendocs
Output markdown docs for rclone to the directory supplied.
Synopsis
This produces markdown docs for the rclone commands to the directory supplied. These are
in a format suitable for hugo to render into the rclone.org website.
rclone gendocs output_directory
rclone listremotes
List all the remotes in the config file.
Synopsis
rclone listremotes lists all the available remotes from the config file.
When uses with the -l flag it lists the types too.
rclone listremotes
Options
-l, --long Show the type as well as names.
rclone mount
Mount the remote as a mountpoint. EXPERIMENTAL
Synopsis
rclone mount allows Linux, FreeBSD and macOS to mount any of Rclone's cloud storage
systems as a file system with FUSE.
This is EXPERIMENTAL - use with care.
First set up your remote using rclone config. Check it works with rclone ls etc.
Start the mount like this (note the & on the end to put rclone in the background).
rclone mount remote:path/to/files /path/to/local/mount &
Stop the mount with
fusermount -u /path/to/local/mount
Or if that fails try
fusermount -z -u /path/to/local/mount
Or with OS X
umount /path/to/local/mount
Limitations
This can only write files seqentially, it can only seek when reading. This means that
many applications won't work with their files on an rclone mount.
The bucket based remotes (eg Swift, S3, Google Compute Storage, B2, Hubic) won't work from
the root - you will need to specify a bucket, or a path within the bucket. So swift:
won't work whereas swift:bucket will as will swift:bucket/path. None of these support the
concept of directories, so empty directories will have a tendency to disappear once they
fall out of the directory cache.
Only supported on Linux, FreeBSD and OS X at the moment.
rclone mount vs rclone sync/copy
File systems expect things to be 100% reliable, whereas cloud storage systems are a long
way from 100% reliable. The rclone sync/copy commands cope with this with lots of
retries. However rclone mount can't use retries in the same way without making local
copies of the uploads. This might happen in the future, but for the moment rclone mount
won't do that, so will be less reliable than the rclone command.
Filters
Note that all the rclone filters can be used to select a subset of the files to be visible
in the mount.
Bugs
• All the remotes should work for read, but some may not for write
• those which need to know the size in advance won't - eg B2
• maybe should pass in size as -1 to mean work it out
• Or put in an an upload cache to cache the files on disk first
TODO
• Check hashes on upload/download
• Preserve timestamps
• Move directories
rclone mount remote:path /path/to/mountpoint
Options
--allow-non-empty Allow mounting over a non-empty directory.
--allow-other Allow access to other users.
--allow-root Allow access to root user.
--debug-fuse Debug the FUSE internals - needs -v.
--default-permissions Makes kernel enforce access control based on the file mode.
--dir-cache-time duration Time to cache directory entries for. (default 5m0s)
--gid uint32 Override the gid field set by the filesystem. (default 502)
--max-read-ahead int The number of bytes that can be prefetched for sequential reads. (default 128k)
--no-modtime Don't read the modification time (can speed things up).
--no-seek Don't allow seeking in files.
--read-only Mount read-only.
--uid uint32 Override the uid field set by the filesystem. (default 502)
--umask int Override the permission bits set by the filesystem. (default 2)
--write-back-cache Makes kernel buffer writes before sending them to rclone. Without this, writethrough caching is used.
rclone moveto
Move file or directory from source to dest.
Synopsis
If source:path is a file or directory then it moves it to a file or directory named
dest:path.
This can be used to rename files or upload single files to other than their existing name.
If the source is a directory then it acts exacty like the move command.
So
rclone moveto src dst
where src and dst are rclone paths, either remote:path or /path/to/local or C:.
This will:
if src is file
move it to dst, overwriting an existing file if it exists
if src is directory
move it to dst, overwriting existing files if they exist
see move command for full details
This doesn't transfer unchanged files, testing by size and modification time or MD5SUM.
src will be deleted on successful transfer.
Important: Since this can cause data loss, test first with the --dry-run flag.
rclone moveto source:path dest:path
rclone obscure
Obscure password for use in the rclone.conf
Synopsis
Obscure password for use in the rclone.conf
rclone obscure password
rclone rmdirs
Remove any empty directoryies under the path.
Synopsis
This removes any empty directories (or directories that only contain empty directories)
under the path that it finds, including the path if it has nothing in.
This is useful for tidying up remotes that rclone has left a lot of empty directories in.
rclone rmdirs remote:path
Copying single files
rclone normally syncs or copies directories. However if the source remote points to a
file, rclone will just copy that file. The destination remote must point to a directory -
rclone will give the error
Failed to create file system for "remote:file": is a file not a directory if it isn't.
For example, suppose you have a remote with a file in called test.jpg, then you could copy
just that file like this
rclone copy remote:test.jpg /tmp/download
The file test.jpg will be placed inside /tmp/download.
This is equivalent to specifying
rclone copy --no-traverse --files-from /tmp/files remote: /tmp/download
Where /tmp/files contains the single line
test.jpg
It is recommended to use copy when copying single files not sync. They have pretty much
the same effect but copy will use a lot less memory.
Quoting and the shell
When you are typing commands to your computer you are using something called the command
line shell. This interprets various characters in an OS specific way.
Here are some gotchas which may help users unfamiliar with the shell rules
Linux / OSX
If your names have spaces or shell metacharacters (eg *, ?, $, ', " etc) then you must
quote them. Use single quotes ' by default.
rclone copy 'Important files?' remote:backup
If you want to send a ' you will need to use ", eg
rclone copy "O'Reilly Reviews" remote:backup
The rules for quoting metacharacters are complicated and if you want the full details
you'll have to consult the manual page for your shell.
Windows
If your names have spaces in you need to put them in ", eg
rclone copy "E:\folder name\folder name\folder name" remote:backup
If you are using the root directory on its own then don't quote it (see #464
(https://github.com/ncw/rclone/issues/464) for why), eg
rclone copy E:\ remote:backup
Server Side Copy
Most remotes (but not all - see the overview (/overview/#optional-features)) support
server side copy.
This means if you want to copy one folder to another then rclone won't download all the
files and re-upload them; it will instruct the server to copy them in place.
Eg
rclone copy s3:oldbucket s3:newbucket
Will copy the contents of oldbucket to newbucket without downloading and re-uploading.
Remotes which don't support server side copy will download and re-upload in this case.
Server side copies are used with sync and copy and will be identified in the log when
using the -v flag. The may also be used with move if the remote doesn't support server
side move.
Server side copies will only be attempted if the remote names are the same.
This can be used when scripting to make aged backups efficiently, eg
rclone sync remote:current-backup remote:previous-backup
rclone sync /path/to/files remote:current-backup
Options
Rclone has a number of options to control its behaviour.
Options which use TIME use the go time parser. A duration string is a possibly signed
sequence of decimal numbers, each with optional fraction and a unit suffix, such as
"300ms", "-1.5h" or "2h45m". Valid time units are "ns", "us" (or "µs"), "ms", "s", "m",
"h".
Options which use SIZE use kByte by default. However a suffix of b for bytes, k for
kBytes, M for MBytes and G for GBytes may be used. These are the binary units, eg 1,
2**10, 2**20, 2**30 respectively.
--backup-dir=DIR
When using sync, copy or move any files which would have been overwritten or deleted are
moved in their original hierarchy into this directory.
If --suffix is set, then the moved files will have the suffix added to them. If there is
a file with the same path (after the suffix has been added) in DIR, then it will be
overwritten.
The remote in use must support server side move or copy and you must use the same remote
as the destination of the sync. The backup directory must not overlap the destination
directory.
For example
rclone sync /path/to/local remote:current --backup-dir remote:old
will sync /path/to/local to remote:current, but for any files which would have been
updated or deleted will be stored in remote:old.
If running rclone from a script you might want to use today's date as the directory name
passed to --backup-dir to store the old files, or you might want to pass --suffix with
today's date.
--bwlimit=BANDWIDTH_SPEC
This option controls the bandwidth limit. Limits can be specified in two ways: As a
single limit, or as a timetable.
Single limits last for the duration of the session. To use a single limit, specify the
desired bandwidth in kBytes/s, or use a suffix b|k|M|G. The default is 0 which means to
not limit bandwidth.
For example to limit bandwidth usage to 10 MBytes/s use --bwlimit 10M
It is also possible to specify a "timetable" of limits, which will cause certain limits to
be applied at certain times. To specify a timetable, format your entries as
"HH:MM,BANDWIDTH HH:MM,BANDWITH...".
An example of a typical timetable to avoid link saturation during daytime working hours
could be:
--bwlimit "08:00,512 12:00,10M 13:00,512 18:00,30M 23:00,off"
In this example, the transfer bandwidth will be set to 512kBytes/sec at 8am. At noon, it
will raise to 10Mbytes/s, and drop back to 512kBytes/sec at 1pm. At 6pm, the bandwidth
limit will be set to 30MBytes/s, and at 11pm it will be completely disabled (full speed).
Anything between 11pm and 8am will remain unlimited.
Bandwidth limits only apply to the data transfer. The don't apply to the bandwidth of the
directory listings etc.
Note that the units are Bytes/s not Bits/s. Typically connections are measured in Bits/s
- to convert divide by 8. For example let's say you have a 10 Mbit/s connection and you
wish rclone to use half of it - 5 Mbit/s. This is 5/8 = 0.625MByte/s so you would use a
--bwlimit 0.625M parameter for rclone.
--buffer-size=SIZE
Use this sized buffer to speed up file transfers. Each --transfer will use this much
memory for buffering.
Set to 0 to disable the buffering for the minimum memory use.
--checkers=N
The number of checkers to run in parallel. Checkers do the equality checking of files
during a sync. For some storage systems (eg s3, swift, dropbox) this can take a
significant amount of time so they are run in parallel.
The default is to run 8 checkers in parallel.
-c, --checksum
Normally rclone will look at modification time and size of files to see if they are equal.
If you set this flag then rclone will check the file hash and size to determine if files
are equal.
This is useful when the remote doesn't support setting modified time and a more accurate
sync is desired than just checking the file size.
This is very useful when transferring between remotes which store the same hash type on
the object, eg Drive and Swift. For details of which remotes support which hash type see
the table in the overview section (http://rclone.org/overview/).
Eg rclone --checksum sync s3:/bucket swift:/bucket would run much quicker than without the
--checksum flag.
When using this flag, rclone won't update mtimes of remote files if they are incorrect as
it would normally.
--config=CONFIG_FILE
Specify the location of the rclone config file.
Normally the config file is in your home directory as a file called
.config/rclone/rclone.conf (or .rclone.conf if created with an older version). If
$XDG_CONFIG_HOME is set it will be at $XDG_CONFIG_HOME/rclone/rclone.conf
If you run rclone -h and look at the help for the --config option you will see where the
default location is for you.
Use this flag to override the config location, eg rclone --config=".myconfig" .config.
--contimeout=TIME
Set the connection timeout. This should be in go time format which looks like 5s for 5
seconds, 10m for 10 minutes, or 3h30m.
The connection timeout is the amount of time rclone will wait for a connection to go
through to a remote object storage system. It is 1m by default.
--dedupe-mode MODE
Mode to run dedupe command in. One of interactive, skip, first, newest, oldest, rename.
The default is interactive. See the dedupe command for more information as to what these
options mean.
-n, --dry-run
Do a trial run with no permanent changes. Use this to see what rclone would do without
actually doing it. Useful when setting up the sync command which deletes files in the
destination.
--ignore-checksum
Normally rclone will check that the checksums of transferred files match, and give an
error "corrupted on transfer" if they don't.
You can use this option to skip that check. You should only use it if you have had the
"corrupted on transfer" error message and you are sure you might want to transfer
potentially corrupted data.
--ignore-existing
Using this option will make rclone unconditionally skip all files that exist on the
destination, no matter the content of these files.
While this isn't a generally recommended option, it can be useful in cases where your
files change due to encryption. However, it cannot correct partial transfers in case a
transfer was interrupted.
--ignore-size
Normally rclone will look at modification time and size of files to see if they are equal.
If you set this flag then rclone will check only the modification time. If --checksum is
set then it only checks the checksum.
It will also cause rclone to skip verifying the sizes are the same after transfer.
This can be useful for transferring files to and from onedrive which occasionally
misreports the size of image files (see #399 (https://github.com/ncw/rclone/issues/399)
for more info).
-I, --ignore-times
Using this option will cause rclone to unconditionally upload all files regardless of the
state of files on the destination.
Normally rclone would skip any files that have the same modification time and are the same
size (or have the same checksum if using --checksum).
--log-file=FILE
Log all of rclone's output to FILE. This is not active by default. This can be useful
for tracking down problems with syncs in combination with the -v flag. See the Logging
section for more info.
--log-level LEVEL
This sets the log level for rclone. The default log level is INFO.
DEBUG is equivalent to -vv. It outputs lots of debug info - useful for bug reports and
really finding out what rclone is doing.
INFO is equivalent to -v. It outputs information about each transfer and prints stats
once a minute by default.
NOTICE is the default log level if no logging flags are supplied. It outputs very little
when things are working normally. It outputs warnings and significant events.
ERROR is equivalent to -q. It only output error messages.
--low-level-retries NUMBER
This controls the number of low level retries rclone does.
A low level retry is used to retry a failing operation - typically one HTTP request. This
might be uploading a chunk of a big file for example. You will see low level retries in
the log with the -v flag.
This shouldn't need to be changed from the default in normal operations, however if you
get a lot of low level retries you may wish to reduce the value so rclone moves on to a
high level retry (see the --retries flag) quicker.
Disable low level retries with --low-level-retries 1.
--max-depth=N
This modifies the recursion depth for all the commands except purge.
So if you do rclone --max-depth 1 ls remote:path you will see only the files in the top
level directory. Using --max-depth 2 means you will see all the files in first two
directory levels and so on.
For historical reasons the lsd command defaults to using a --max-depth of 1 - you can
override this with the command line flag.
You can use this command to disable recursion (with --max-depth 1).
Note that if you use this with sync and --delete-excluded the files not recursed through
are considered excluded and will be deleted on the destination. Test first with --dry-run
if you are not sure what will happen.
--modify-window=TIME
When checking whether a file has been modified, this is the maximum allowed time
difference that a file can have and still be considered equivalent.
The default is 1ns unless this is overridden by a remote. For example OS X only stores
modification times to the nearest second so if you are reading and writing to an OS X
filing system this will be 1s by default.
This command line flag allows you to override that computed default.
--no-gzip-encoding
Don't set Accept-Encoding: gzip. This means that rclone won't ask the server for
compressed files automatically. Useful if you've set the server to return files with
Content-Encoding: gzip but you uploaded compressed files.
There is no need to set this in normal operation, and doing so will decrease the network
transfer efficiency of rclone.
--no-update-modtime
When using this flag, rclone won't update modification times of remote files if they are
incorrect as it would normally.
This can be used if the remote is being synced with another tool also (eg the Google Drive
client).
-q, --quiet
Normally rclone outputs stats and a completion message. If you set this flag it will make
as little output as possible.
--retries int
Retry the entire sync if it fails this many times it fails (default 3).
Some remotes can be unreliable and a few retries helps pick up the files which didn't get
transferred because of errors.
Disable retries with --retries 1.
--size-only
Normally rclone will look at modification time and size of files to see if they are equal.
If you set this flag then rclone will check only the size.
This can be useful transferring files from dropbox which have been modified by the desktop
sync client which doesn't set checksums of modification times in the same way as rclone.
--stats=TIME
Commands which transfer data (sync, copy, copyto, move, moveto) will print data transfer
stats at regular intervals to show their progress.
This sets the interval.
The default is 1m. Use 0 to disable.
If you set the stats interval then all command can show stats. This can be useful when
running other commands, check or mount for example.
--stats-unit=bits|bytes
By default data transfer rates will be printed in bytes/second.
This option allows the data rate to be printed in bits/second.
Data transfer volume will still be reported in bytes.
The rate is reported as a binary unit, not SI unit. So 1 Mbit/s equals 1,048,576 bits/s
and not 1,000,000 bits/s.
The default is bytes.
--suffix=SUFFIX
This is for use with --backup-dir only. If this isn't set then --backup-dir will move
files with their original name. If it is set then the files will have SUFFIX added on to
them.
See --backup-dir for more info.
--syslog
On capable OSes (not Windows or Plan9) send all log output to syslog.
This can be useful for running rclone in script or rclone mount.
--syslog-facility string
If using --syslog this sets the syslog facility (eg KERN, USER). See man syslog for a
list of possible facilities. The default facility is DAEMON.
--track-renames
By default rclone doesn't not keep track of renamed files, so if you rename a file locally
then sync it to a remote, rclone will delete the old file on the remote and upload a new
copy.
If you use this flag, and the remote supports server side copy or server side move, and
the source and destination have a compatible hash, then this will track renames during
sync, copy, and move operations and perform renaming server-side.
Files will be matched by size and hash - if both match then a rename will be considered.
If the destination does not support server-side copy or move, rclone will fall back to the
default behaviour and log an error level message to the console.
Note that --track-renames is incompatible with --no-traverse and that it uses extra memory
to keep track of all the rename candidates.
Note also that --track-renames is incompatible with --delete-before and will select
--delete-after instead of --delete-during.
--delete-(before,during,after)
This option allows you to specify when files on your destination are deleted when you sync
folders.
Specifying the value --delete-before will delete all files present on the destination, but
not on the source before starting the transfer of any new or updated files. This uses two
passes through the file systems, one for the deletions and one for the copies.
Specifying --delete-during will delete files while checking and uploading files. This is
the fastest option and uses the least memory.
Specifying --delete-after (the default value) will delay deletion of files until all
new/updated files have been successfully transferred. The files to be deleted are
collected in the copy pass then deleted after the copy pass has completed sucessfully.
The files to be deleted are held in memory so this mode may use more memory. This is the
safest mode as it will only delete files if there have been no errors subsequent to that.
If there have been errors before the deletions start then you will get the message
not deleting files as there were IO errors.
--timeout=TIME
This sets the IO idle timeout. If a transfer has started but then becomes idle for this
long it is considered broken and disconnected.
The default is 5m. Set to 0 to disable.
--transfers=N
The number of file transfers to run in parallel. It can sometimes be useful to set this
to a smaller number if the remote is giving a lot of timeouts or bigger if you have lots
of bandwidth and a fast remote.
The default is to run 4 file transfers in parallel.
-u, --update
This forces rclone to skip any files which exist on the destination and have a modified
time that is newer than the source file.
If an existing destination file has a modification time equal (within the computed modify
window precision) to the source file's, it will be updated if the sizes are different.
On remotes which don't support mod time directly the time checked will be the uploaded
time. This means that if uploading to one of these remoes, rclone will skip any files
which exist on the destination and have an uploaded time that is newer than the
modification time of the source file.
This can be useful when transferring to a remote which doesn't support mod times directly
as it is more accurate than a --size-only check and faster than using --checksum.
-v, -vv, --verbose
With -v rclone will tell you about each file that is transferred and a small number of
significant events.
With -vv rclone will become very verbose telling you about every file it considers and
transfers. Please send bug reports with a log with this setting.
-V, --version
Prints the version number
Configuration Encryption
Your configuration file contains information for logging in to your cloud services. This
means that you should keep your .rclone.conf file in a secure location.
If you are in an environment where that isn't possible, you can add a password to your
configuration. This means that you will have to enter the password every time you start
rclone.
To add a password to your rclone configuration, execute rclone config.
>rclone config
Current remotes:
e) Edit existing remote
n) New remote
d) Delete remote
s) Set configuration password
q) Quit config
e/n/d/s/q>
Go into s, Set configuration password:
e/n/d/s/q> s
Your configuration is not encrypted.
If you add a password, you will protect your login information to cloud services.
a) Add Password
q) Quit to main menu
a/q> a
Enter NEW configuration password:
password:
Confirm NEW password:
password:
Password set
Your configuration is encrypted.
c) Change Password
u) Unencrypt configuration
q) Quit to main menu
c/u/q>
Your configuration is now encrypted, and every time you start rclone you will now be asked
for the password. In the same menu you can change the password or completely remove
encryption from your configuration.
There is no way to recover the configuration if you lose your password.
rclone uses nacl secretbox (https://godoc.org/golang.org/x/crypto/nacl/secretbox) which in
turn uses XSalsa20 and Poly1305 to encrypt and authenticate your configuration with
secret-key cryptography. The password is SHA-256 hashed, which produces the key for
secretbox. The hashed password is not stored.
While this provides very good security, we do not recommend storing your encrypted rclone
configuration in public if it contains sensitive information, maybe except if you use a
very strong password.
If it is safe in your environment, you can set the RCLONE_CONFIG_PASS environment variable
to contain your password, in which case it will be used for decrypting the configuration.
You can set this for a session from a script. For unix like systems save this to a file
called set-rclone-password:
#!/bin/echo Source this file don't run it
read -s RCLONE_CONFIG_PASS
export RCLONE_CONFIG_PASS
Then source the file when you want to use it. From the shell you would do
source set-rclone-password. It will then ask you for the password and set it in the
envonment variable.
If you are running rclone inside a script, you might want to disable password prompts. To
do that, pass the parameter --ask-password=false to rclone. This will make rclone fail
instead of asking for a password if RCLONE_CONFIG_PASS doesn't contain a valid password.
Developer options
These options are useful when developing or debugging rclone. There are also some more
remote specific options which aren't documented here which are used for testing. These
start with remote name eg --drive-test-option - see the docs for the remote in question.
--cpuprofile=FILE
Write CPU profile to file. This can be analysed with go tool pprof.
--dump-auth
Dump HTTP headers - will contain sensitive info such as Authorization: headers - use
--dump-headers to dump without Authorization: headers. Can be very verbose. Useful for
debugging only.
--dump-bodies
Dump HTTP headers and bodies - may contain sensitive info. Can be very verbose. Useful
for debugging only.
--dump-filters
Dump the filters to the output. Useful to see exactly what include and exclude options
are filtering on.
--dump-headers
Dump HTTP headers with Authorization: lines removed. May still contain sensitive info.
Can be very verbose. Useful for debugging only.
Use --dump-auth if you do want the Authorization: headers.
--memprofile=FILE
Write memory profile to file. This can be analysed with go tool pprof.
--no-check-certificate=true/false
--no-check-certificate controls whether a client verifies the server's certificate chain
and host name. If --no-check-certificate is true, TLS accepts any certificate presented
by the server and any host name in that certificate. In this mode, TLS is susceptible to
man-in-the-middle attacks.
This option defaults to false.
This should be used only for testing.
--no-traverse
The --no-traverse flag controls whether the destination file system is traversed when
using the copy or move commands. --no-traverse is not compatible with sync and will be
ignored if you supply it with sync.
If you are only copying a small number of files and/or have a large number of files on the
destination then --no-traverse will stop rclone listing the destination and save time.
However if you are copying a large number of files, escpecially if you are doing a copy
where lots of the files haven't changed and won't need copying then you shouldn't use
--no-traverse.
It can also be used to reduce the memory usage of rclone when copying -
rclone --no-traverse copy src dst won't load either the source or destination listings
into memory so will use the minimum amount of memory.
Filtering
For the filtering options
• --delete-excluded
• --filter
• --filter-from
• --exclude
• --exclude-from
• --include
• --include-from
• --files-from
• --min-size
• --max-size
• --min-age
• --max-age
• --dump-filters
See the filtering section (http://rclone.org/filtering/).
Logging
rclone has 4 levels of logging, Error, Notice, Info and Debug.
By default rclone logs to standard error. This means you can redirect standard error and
still see the normal output of rclone commands (eg rclone ls).
By default rclone will produce Error and Notice level messages.
If you use the -q flag, rclone will only produce Error messages.
If you use the -v flag, rclone will produce Error, Notice and Info messages.
If you use the -vv flag, rclone will produce Error, Notice, Info and Debug messages.
You can also control the log levels with the --log-level flag.
If you use the --log-file=FILE option, rclone will redirect Error, Info and Debug messages
along with standard error to FILE.
If you use the --syslog flag then rclone will log to syslog and the --syslog-facility
control which facility it uses.
Rclone prefixes all log messages with their level in capitals, eg INFO which makes it easy
to grep the log file for different kinds of information.
Exit Code
If any errors occurred during the command, rclone will exit with a non-zero exit code.
This allows scripts to detect when rclone operations have failed.
During the startup phase rclone will exit immediately if an error is detected in the
configuration. There will always be a log message immediately before exiting.
When rclone is running it will accumulate errors as it goes along, and only exit with an
non-zero exit code if (after retries) there were still failed transfers. For every error
counted there will be a high priority log message (visibile with -q) showing the message
and which file caused the problem. A high priority message is also shown when starting a
retry so the user can see that any previous error messages may not be valid after the
retry. If rclone has done a retry it will log a high priority message if the retry was
successful.
Environment Variables
Rclone can be configured entirely using environment variables. These can be used to set
defaults for options or config file entries.
Options
Every option in rclone can have its default set by environment variable.
To find the name of the environment variable, first take the long option name, strip the
leading --, change - to _, make upper case and prepend RCLONE_.
For example to always set --stats 5s, set the environment variable RCLONE_STATS=5s. If
you set stats on the command line this will override the environment variable setting.
Or to always use the trash in drive --drive-use-trash, set RCLONE_DRIVE_USE_TRASH=true.
The same parser is used for the options and the environment variables so they take exactly
the same form.
Config file
You can set defaults for values in the config file on an individual remote basis. If you
want to use this feature, you will need to discover the name of the config items that you
want. The easiest way is to run through rclone config by hand, then look in the config
file to see what the values are (the config file can be found by looking at the help for
--config in rclone help).
To find the name of the environment variable, you need to set, take RCLONE_ + name of
remote + _ + name of config file option and make it all uppercase.
For example to configure an S3 remote named mys3: without a config file (using unix ways
of setting environment variables):
$ export RCLONE_CONFIG_MYS3_TYPE=s3
$ export RCLONE_CONFIG_MYS3_ACCESS_KEY_ID=XXX
$ export RCLONE_CONFIG_MYS3_SECRET_ACCESS_KEY=XXX
$ rclone lsd MYS3:
-1 2016-09-21 12:54:21 -1 my-bucket
$ rclone listremotes | grep mys3
mys3:
Note that if you want to create a remote using environment variables you must create the
..._TYPE variable as above.
Other environment variables
• RCLONE_CONFIG_PASS` set to contain your config file password (see Configuration
Encryption (#configuration-encryption) section)
• HTTP_PROXY, HTTPS_PROXY and NO_PROXY (or the lowercase versions thereof).
• HTTPS_PROXY takes precedence over HTTP_PROXY for https requests.
• The environment values may be either a complete URL or a "host[:port]" for, in which
case the "http" scheme is assumed.
Configuring rclone on a remote / headless machine
Some of the configurations (those involving oauth2) require an Internet connected web
browser.
If you are trying to set rclone up on a remote or headless box with no browser available
on it (eg a NAS or a server in a datacenter) then you will need to use an alternative
means of configuration. There are two ways of doing it, described below.
Configuring using rclone authorize
On the headless box
...
Remote config
Use auto config?
* Say Y if not sure
* Say N if you are working on a remote or headless machine
y) Yes
n) No
y/n> n
For this to work, you will need rclone available on a machine that has a web browser available.
Execute the following on your machine:
rclone authorize "amazon cloud drive"
Then paste the result below:
result>
Then on your main desktop machine
rclone authorize "amazon cloud drive"
If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth
Log in and authorize rclone for access
Waiting for code...
Got code
Paste the following into your remote machine --->
SECRET_TOKEN
<---End paste
Then back to the headless box, paste in the code
result> SECRET_TOKEN
--------------------
[acd12]
client_id =
client_secret =
token = SECRET_TOKEN
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d>
Configuring by copying the config file
Rclone stores all of its config in a single configuration file. This can easily be copied
to configure a remote rclone.
So first configure rclone on your desktop machine
rclone config
to set up the config file.
Find the config file by running rclone -h and looking for the help for the --config option
$ rclone -h
[snip]
--config="/home/user/.rclone.conf": Config file.
[snip]
Now transfer it to the remote box (scp, cut paste, ftp, sftp etc) and place it in the
correct place (use rclone -h on the remote box to find out where).
Filtering, includes and excludes
Rclone has a sophisticated set of include and exclude rules. Some of these are based on
patterns and some on other things like file size.
The filters are applied for the copy, sync, move, ls, lsl, md5sum, sha1sum, size, delete
and check operations. Note that purge does not obey the filters.
Each path as it passes through rclone is matched against the include and exclude rules
like --include, --exclude, --include-from, --exclude-from, --filter, or --filter-from.
The simplest way to try them out is using the ls command, or --dry-run together with -v.
Patterns
The patterns used to match files for inclusion or exclusion are based on "file globs" as
used by the unix shell.
If the pattern starts with a / then it only matches at the top level of the directory
tree, relative to the root of the remote (not necessarily the root of the local drive).
If it doesn't start with / then it is matched starting at the end of the path, but it will
only match a complete path element:
file.jpg - matches "file.jpg"
- matches "directory/file.jpg"
- doesn't match "afile.jpg"
- doesn't match "directory/afile.jpg"
/file.jpg - matches "file.jpg" in the root directory of the remote
- doesn't match "afile.jpg"
- doesn't match "directory/file.jpg"
Important Note that you must use / in patterns and not \ even if running on Windows.
A * matches anything but not a /.
*.jpg - matches "file.jpg"
- matches "directory/file.jpg"
- doesn't match "file.jpg/something"
Use ** to match anything, including slashes (/).
dir/** - matches "dir/file.jpg"
- matches "dir/dir1/dir2/file.jpg"
- doesn't match "directory/file.jpg"
- doesn't match "adir/file.jpg"
A ? matches any character except a slash /.
l?ss - matches "less"
- matches "lass"
- doesn't match "floss"
A [ and ] together make a a character class, such as [a-z] or [aeiou] or [[:alpha:]]. See
the go regexp docs (https://golang.org/pkg/regexp/syntax/) for more info on these.
h[ae]llo - matches "hello"
- matches "hallo"
- doesn't match "hullo"
A { and } define a choice between elements. It should contain a comma separated list of
patterns, any of which might match. These patterns can contain wildcards.
{one,two}_potato - matches "one_potato"
- matches "two_potato"
- doesn't match "three_potato"
- doesn't match "_potato"
Special characters can be escaped with a \ before them.
\*.jpg - matches "*.jpg"
\\.jpg - matches "\.jpg"
\[one\].jpg - matches "[one].jpg"
Note also that rclone filter globs can only be used in one of the filter command line
flags, not in the specification of the remote, so
rclone copy "remote:dir*.jpg" /path/to/dir won't work - what is required is
rclone --include "*.jpg" copy remote:dir /path/to/dir
Directories
Rclone keeps track of directories that could match any file patterns.
Eg if you add the include rule
/a/*.jpg
Rclone will synthesize the directory include rule
/a/
If you put any rules which end in / then it will only match directories.
Directory matches are only used to optimise directory access patterns - you must still
match the files that you want to match. Directory matches won't optimise anything on
bucket based remotes (eg s3, swift, google compute storage, b2) which don't have a concept
of directory.
Differences between rsync and rclone patterns
Rclone implements bash style {a,b,c} glob matching which rsync doesn't.
Rclone always does a wildcard match so \ must always escape a \.
How the rules are used
Rclone maintains a combined list of include rules and exclude rules.
Each file is matched in order, starting from the top, against the rule in the list until
it finds a match. The file is then included or excluded according to the rule type.
If the matcher fails to find a match after testing against all the entries in the list
then the path is included.
For example given the following rules, + being include, - being exclude,
- secret*.jpg
+ *.jpg
+ *.png
+ file2.avi
- *
This would include
• file1.jpg
• file3.png
• file2.avi
This would exclude
• secret17.jpg
• non *.jpg and *.png
A similar process is done on directory entries before recursing into them. This only
works on remotes which have a concept of directory (Eg local, google drive, onedrive,
amazon drive) and not on bucket based remotes (eg s3, swift, google compute storage, b2).
Adding filtering rules
Filtering rules are added with the following command line flags.
Repeating options
You can repeat the following options to add more than one rule of that type.
• --include
• --include-from
• --exclude
• --exclude-from
• --filter
• --filter-from
Note that all the options of the same type are processed together in the order above,
regardless of what order they were placed on the command line.
So all --include options are processed first in the order they appeared on the command
line, then all --include-from options etc.
To mix up the order includes and excludes, the --filter flag can be used.
--exclude - Exclude files matching pattern
Add a single exclude rule with --exclude.
This flag can be repeated. See above for the order the flags are processed in.
Eg --exclude *.bak to exclude all bak files from the sync.
--exclude-from - Read exclude patterns from file
Add exclude rules from a file.
This flag can be repeated. See above for the order the flags are processed in.
Prepare a file like this exclude-file.txt
# a sample exclude rule file
*.bak
file2.jpg
Then use as --exclude-from exclude-file.txt. This will sync all files except those ending
in bak and file2.jpg.
This is useful if you have a lot of rules.
--include - Include files matching pattern
Add a single include rule with --include.
This flag can be repeated. See above for the order the flags are processed in.
Eg --include *.{png,jpg} to include all png and jpg files in the backup and no others.
This adds an implicit --exclude * at the very end of the filter list. This means you can
mix --include and --include-from with the other filters (eg --exclude) but you must
include all the files you want in the include statement. If this doesn't provide enough
flexibility then you must use --filter-from.
--include-from - Read include patterns from file
Add include rules from a file.
This flag can be repeated. See above for the order the flags are processed in.
Prepare a file like this include-file.txt
# a sample include rule file
*.jpg
*.png
file2.avi
Then use as --include-from include-file.txt. This will sync all jpg, png files and
file2.avi.
This is useful if you have a lot of rules.
This adds an implicit --exclude * at the very end of the filter list. This means you can
mix --include and --include-from with the other filters (eg --exclude) but you must
include all the files you want in the include statement. If this doesn't provide enough
flexibility then you must use --filter-from.
--filter - Add a file-filtering rule
This can be used to add a single include or exclude rule. Include rules start with + and
exclude rules start with -. A special rule called ! can be used to clear the existing
rules.
This flag can be repeated. See above for the order the flags are processed in.
Eg --filter "- *.bak" to exclude all bak files from the sync.
--filter-from - Read filtering patterns from a file
Add include/exclude rules from a file.
This flag can be repeated. See above for the order the flags are processed in.
Prepare a file like this filter-file.txt
# a sample exclude rule file
- secret*.jpg
+ *.jpg
+ *.png
+ file2.avi
# exclude everything else
- *
Then use as --filter-from filter-file.txt. The rules are processed in the order that they
are defined.
This example will include all jpg and png files, exclude any files matching secret*.jpg
and include file2.avi. Everything else will be excluded from the sync.
--files-from - Read list of source-file names
This reads a list of file names from the file passed in and only these files are
transferred. The filtering rules are ignored completely if you use this option.
This option can be repeated to read from more than one file. These are read in the order
that they are placed on the command line.
Prepare a file like this files-from.txt
# comment
file1.jpg
file2.jpg
Then use as --files-from files-from.txt. This will only transfer file1.jpg and file2.jpg
providing they exist.
For example, let's say you had a few files you want to back up regularly with these
absolute paths:
/home/user1/important
/home/user1/dir/file
/home/user2/stuff
To copy these you'd find a common subdirectory - in this case /home and put the remaining
files in files-from.txt with or without leading /, eg
user1/important
user1/dir/file
user2/stuff
You could then copy these to a remote like this
rclone copy --files-from files-from.txt /home remote:backup
The 3 files will arrive in remote:backup with the paths as in the files-from.txt.
You could of course choose / as the root too in which case your files-from.txt might look
like this.
/home/user1/important
/home/user1/dir/file
/home/user2/stuff
And you would transfer it like this
rclone copy --files-from files-from.txt / remote:backup
In this case there will be an extra home directory on the remote.
--min-size - Don't transfer any file smaller than
this
This option controls the minimum size file which will be transferred. This defaults to
kBytes but a suffix of k, M, or G can be used.
For example --min-size 50k means no files smaller than 50kByte will be transferred.
--max-size - Don't transfer any file larger than
this
This option controls the maximum size file which will be transferred. This defaults to
kBytes but a suffix of k, M, or G can be used.
For example --max-size 1G means no files larger than 1GByte will be transferred.
--max-age - Don't transfer any file older than this
This option controls the maximum age of files to transfer. Give in seconds or with a
suffix of:
• ms - Milliseconds
• s - Seconds
• m - Minutes
• h - Hours
• d - Days
• w - Weeks
• M - Months
• y - Years
For example --max-age 2d means no files older than 2 days will be transferred.
--min-age - Don't transfer any file younger than
this
This option controls the minimum age of files to transfer. Give in seconds or with a
suffix (see --max-age for list of suffixes)
For example --min-age 2d means no files younger than 2 days will be transferred.
--delete-excluded - Delete files on dest excluded from
sync
Important this flag is dangerous - use with --dry-run and -v first.
When doing rclone sync this will delete any files which are excluded from the sync on the
destination.
If for example you did a sync from A to B without the --min-size 50k flag
rclone sync A: B:
Then you repeated it like this with the --delete-excluded
rclone --min-size 50k --delete-excluded sync A: B:
This would delete all files on B which are less than 50 kBytes as these are now excluded
from the sync.
Always test first with --dry-run and -v before using this flag.
--dump-filters - dump the filters to the output
This dumps the defined filters to the output as regular expressions.
Useful for debugging.
Quoting shell metacharacters
The examples above may not work verbatim in your shell as they have shell metacharacters
in them (eg *), and may require quoting.
Eg linux, OSX
• --include \*.jpg
• --include '*.jpg'
• --include='*.jpg'
In Windows the expansion is done by the command not the shell so this should work fine
• --include *.jpg
Overview of cloud storage systems
Each cloud storage system is slighly different. Rclone attempts to provide a unified
interface to them, but some underlying differences show through.
Features
Here is an overview of the major features of each cloud storage system.
Name Hash ModTime Case Duplicate MIME Type
Insensitive Files
──────────────────────────────────────────────────────────────────────
Google Drive MD5 Yes No Yes R/W
Amazon S3 MD5 Yes No No R/W
Openstack MD5 Yes No No R/W

Dropbox - No Yes No R
Google Cloud MD5 Yes No No R/W
Storage
Amazon Drive MD5 No Yes No R
Microsoft One SHA1 Yes Yes No R
Drive
Hubic MD5 Yes No No R/W
Backblaze B2 SHA1 Yes No No R/W
Yandex Disk MD5 Yes No No R/W
SFTP - Yes Depends No -
The local All Yes Depends No -
filesystem
Hash
The cloud storage system supports various hash types of the objects.
The hashes are used when transferring data as an integrity check and can be specifically
used with the --checksum flag in syncs and in the check command.
To use the checksum checks between filesystems they must support a common hash type.
ModTime
The cloud storage system supports setting modification times on objects. If it does then
this enables a using the modification times as part of the sync. If not then only the
size will be checked by default, though the MD5SUM can be checked with the --checksum
flag.
All cloud storage systems support some kind of date on the object and these will be set
when transferring from the cloud storage system.
Case Insensitive
If a cloud storage systems is case sensitive then it is possible to have two files which
differ only in case, eg file.txt and FILE.txt. If a cloud storage system is case
insensitive then that isn't possible.
This can cause problems when syncing between a case insensitive system and a case
sensitive system. The symptom of this is that no matter how many times you run the sync
it never completes fully.
The local filesystem and SFTP may or may not be case sensitive depending on OS.
• Windows - usually case insensitive, though case is preserved
• OSX - usually case insensitive, though it is possible to format case sensitive
• Linux - usually case sensitive, but there are case insensitive file systems (eg FAT
formatted USB keys)
Most of the time this doesn't cause any problems as people tend to avoid files whose name
differs only by case even on case sensitive systems.
Duplicate files
If a cloud storage system allows duplicate files then it can have two objects with the
same name.
This confuses rclone greatly when syncing - use the rclone dedupe command to rename or
remove duplicates.
MIME Type
MIME types (also known as media types) classify types of documents using a simple text
classification, eg text/html or application/pdf.
Some cloud storage systems support reading (R) the MIME type of objects and some support
writing (W) the MIME type of objects.
The MIME type can be important if you are serving files directly to HTTP from the storage
system.
If you are copying from a remote which supports reading (R) to a remote which supports
writing (W) then rclone will preserve the MIME types. Otherwise they will be guessed from
the extension, or the remote itself may assign the MIME type.
Optional Features
All the remotes support a basic set of features, but there are some optional features
supported by some remotes used to make some operations more efficient.

Purge
This deletes a directory quicker than just deleting all the files in the directory.
† Note Swift and Hubic implement this in order to delete directory markers but they don't
actually have a quicker way of deleting files other than deleting them individually.
Copy
Used when copying an object to and from the same remote. This known as a server side copy
so you can copy a file without downloading it and uploading it again. It is used if you
use rclone copy or rclone move if the remote doesn't support Move directly.
If the server doesn't support Copy directly then for copy operations the file is
downloaded then re-uploaded.
Move
Used when moving/renaming an object on the same remote. This is known as a server side
move of a file. This is used in rclone move if the server doesn't support DirMove.
If the server isn't capable of Move then rclone simulates it with Copy then delete. If
the server doesn't support Copy then rclone will download the file and re-upload it.
DirMove
This is used to implement rclone move to move a directory if possible. If it isn't then
it will use Move on each file (which falls back to Copy then download and upload - see
Move section).
CleanUp
This is used for emptying the trash for a remote by rclone cleanup.
If the server can't do CleanUp then rclone cleanup will return an error.
Google Drive
Paths are specified as drive:path
Drive paths may be as deep as required, eg drive:directory/subdirectory.
The initial setup for drive involves getting a token from Google drive which you need to
do in your browser. rclone config walks you through it.
Here is an example of how to make a remote called remote. First run:
rclone config
This will guide you through an interactive setup process:

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
Note that rclone runs a webserver on your local machine to collect the token as returned
from Google if you use auto config mode. This only runs from the moment it opens your
browser to the moment you get back the verification code. This is on
http://127.0.0.1:53682/ and this it may require you to unblock it temporarily if you are
running a host firewall, or use manual mode.
You can then use it like this,
List directories in top level of your drive
rclone lsd remote:
List all the files in your drive
rclone ls remote:
To copy a local directory to a drive directory called backup
rclone copy /home/source remote:backup
Modified time
Google drive stores modification times accurate to 1 ms.
Revisions
Google drive stores revisions of files. When you upload a change to an existing file to
google drive using rclone it will create a new revision of that file.
Revisions follow the standard google policy which at time of writing was
• They are deleted after 30 days or 100 revisions (whatever comes first).
• They do not count towards a user storage quota.
Deleting files
By default rclone will delete files permanently when requested. If sending them to the
trash is required instead then use the --drive-use-trash flag.
Specific options
Here are the command line options specific to this cloud storage system.
--drive-chunk-size=SIZE
Upload chunk size. Must a power of 2 >= 256k. Default value is 8 MB.
Making this larger will improve performance, but note that each chunk is buffered in
memory one per transfer.
Reducing this will reduce memory usage but decrease performance.
--drive-full-list
No longer does anything - kept for backwards compatibility.
--drive-upload-cutoff=SIZE
File size cutoff for switching to chunked upload. Default is 8 MB.
--drive-use-trash
Send files to the trash instead of deleting permanently. Defaults to off, namely deleting
files permanently.
--drive-auth-owner-only
Only consider files owned by the authenticated user. Requires that --drive-full-list=true
(default).
--drive-formats
Google documents can only be exported from Google drive. When rclone downloads a Google
doc it chooses a format to download depending upon this setting.
By default the formats are docx,xlsx,pptx,svg which are a sensible default for an editable
document.
When choosing a format, rclone runs down the list provided in order and chooses the first
file format the doc can be exported as from the list. If the file can't be exported to a
format on the formats list, then rclone will choose a format from the default list.
If you prefer an archive copy then you might use --drive-formats pdf, or if you prefer
openoffice/libreoffice formats you might use --drive-formats ods,odt,odp.
Note that rclone adds the extension to the google doc, so if it is calles My Spreadsheet
on google docs, it will be exported as My Spreadsheet.xlsx or My Spreadsheet.pdf etc.
Here are the possible extensions with their corresponding mime types.

--drive-skip-gdocs
Skip google documents in all listings. If given, gdocs practically become invisible to
rclone.
Limitations
Drive has quite a lot of rate limiting. This causes rclone to be limited to transferring
about 2 files per second only. Individual files may be transferred much faster at 100s of
MBytes/s but lots of small files can take a long time.
Making your own client_id
When you use rclone with Google drive in its default configuration you are using rclone's
client_id. This is shared between all the rclone users. There is a global rate limit on
the number of queries per second that each client_id can do set by Google. rclone already
has a high quota and I will continue to make sure it is high enough by contacting Google.
However you might find you get better performance making your own client_id if you are a
heavy user. Or you may not depending on exactly how Google have been raising rclone's
rate limit.
Here is how to create your own Google Drive client ID for rclone:
1. Log into the Google API Console (https://console.developers.google.com/) with your
Google account. It doesn't matter what Google account you use. (It need not be the
same account as the Google Drive you want to access)
2. Select a project or create a new project.
3. Under Overview, Google APIs, Google Apps APIs, click "Drive API", then "Enable".
4. Click "Credentials" in the left-side panel (not "Go to credentials", which opens the
wizard), then "Create credentials", then "OAuth client ID". It will prompt you to set
the OAuth consent screen product name, if you haven't set one already.
5. Choose an application type of "other", and click "Create". (the default name is fine)
6. It will show you a client ID and client secret. Use these values in rclone config to
add a new remote or edit an existing remote.
(Thanks to @balazer on github for these instructions.)

subdirectories in too, eg remote:bucket/path/to/dir.

With Amazon S3 you can list buckets (rclone lsd) using any region, but you can only access
the content of a bucket from the region it was created in. If you attempt to access a
bucket from the wrong region, you will get an error,
incorrect region, the bucket is not in 'XXX' region.
Authentication
There are two ways to supply rclone with a set of AWS credentials. In order of
precedence:
• Directly in the rclone configuration file (as configured by rclone config)
• set access_key_id and secret_access_key
• Runtime configuration:
• set env_auth to true in the config file
• Exporting the following environment variables before running rclone
• Access Key ID: AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY
• Secret Access Key: AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY
• Running rclone on an EC2 instance with an IAM role
If none of these option actually end up providing rclone with AWS credentials then S3
interaction will be non-authenticated (see below).
Specific options
Here are the command line options specific to this cloud storage system.
--s3-acl=STRING
Canned ACL used when creating buckets and/or storing objects in S3.
For more info visit the canned ACL docs
(http://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html#canned-acl).
--s3-storage-class=STRING
Storage class to upload new objects with.
Available options include:
• STANDARD - default storage class
• STANDARD_IA - for less frequently accessed data (e.g backups)
• REDUCED_REDUNDANCY (only for noncritical, reproducible data, has lower redundancy)
Anonymous access to public buckets
If you want to use rclone to access a public bucket, configure with a blank access_key_id
and secret_access_key. Eg
No remotes found - make a new one
n) New remote
q) Quit config
n/q> n
name> anons3
What type of source is it?
Choose a number from below
1) amazon cloud drive
2) b2
3) drive
4) dropbox
5) google cloud storage
6) swift
7) hubic
8) local
9) onedrive
10) s3
11) yandex
type> 10
Get AWS credentials from runtime (environment variables or EC2 meta data if no env vars). Only applies if access_key_id and secret_access_key is blank.
Choose a number from below, or type in your own value
* Enter AWS credentials in the next step
1) false
* Get AWS credentials from the environment (env vars or IAM)
2) true
env_auth> 1
AWS Access Key ID - leave blank for anonymous access or runtime credentials.
access_key_id>
AWS Secret Access Key (password) - leave blank for anonymous access or runtime credentials.
secret_access_key>
...
Then use it as normal with the name of the public bucket, eg
rclone lsd anons3:1000genomes
You will be able to list and copy data but not upload it.
Ceph
Ceph is an object storage system which presents an Amazon S3 interface.
To use rclone with ceph, you need to set the following parameters in the config.
access_key_id = Whatever
secret_access_key = Whatever
endpoint = https://ceph.endpoint.goes.here/
region = other-v2-signature
Note also that Ceph sometimes puts / in the passwords it gives users. If you read the
secret access key using the command line tools you will get a JSON blob with the / escaped
as \/. Make sure you only write / in the secret access key.
Eg the dump from Ceph looks something like this (irrelevant keys removed).
{
"user_id": "xxx",
"display_name": "xxxx",
"keys": [
{
"user": "xxx",
"access_key": "xxxxxx",
"secret_key": "xxxxxx\/xxxx"
}
],
}
Because this is a json dump, it is encoding the / as \/, so if you use the secret key as
xxxxxx/xxxx it will work fine.
Minio
Minio (https://minio.io/) is an object storage server built for cloud application
developers and devops.
It is very easy to install and provides an S3 compatible server which can be used by
rclone.
To use it, install Minio following the instructions from the web site.
When it configures itself Minio will print something like this
AccessKey: WLGDGYAQYIGI833EV05A SecretKey: BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF Region: us-east-1
Minio Object Storage:
http://127.0.0.1:9000
http://10.0.0.3:9000
Minio Browser:
http://127.0.0.1:9000
http://10.0.0.3:9000
These details need to go into rclone config like this. Note that it is important to put
the region in as stated above.
env_auth> 1
access_key_id> WLGDGYAQYIGI833EV05A
secret_access_key> BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF
region> us-east-1
endpoint> http://10.0.0.3:9000
location_constraint>
server_side_encryption>
Which makes the config file look like this
[minio]
env_auth = false
access_key_id = WLGDGYAQYIGI833EV05A
secret_access_key = BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF
region = us-east-1
endpoint = http://10.0.0.3:9000
location_constraint =
server_side_encryption =
Minio doesn't support all the features of S3 yet. In particular it doesn't support MD5
checksums (ETags) or metadata. This means rclone can't check MD5SUMs or store the
modified date. However you can work around this with the --size-only flag of rclone.
So once set up, for example to copy files into a bucket
rclone --size-only copy /path/to/files minio:bucket
Swift
Swift refers to Openstack Object Storage (http://www.openstack.org/software/openstack-
storage/). Commercial implementations of that being:
• Rackspace Cloud Files (http://www.rackspace.com/cloud/files/)
• Memset Memstore (http://www.memset.com/cloud/storage/)
Paths are specified as remote:container (or remote: for the lsd command.) You may put
subdirectories in too, eg remote:container/path/to/dir.
Here is an example of making a swift configuration. First run
rclone config
This will guide you through an interactive setup process.

rclone mkdir remote:container
List the contents of a container
rclone ls remote:container
Sync /home/local/directory to the remote container, deleting any excess files in the
container.
rclone sync /home/local/directory remote:container
Configuration from an Openstack credentials file
An Opentstack credentials file typically looks something something like this (without the
comments)
export OS_AUTH_URL=https://a.provider.net/v2.0
export OS_TENANT_ID=ffffffffffffffffffffffffffffffff
export OS_TENANT_NAME="1234567890123456"
export OS_USERNAME="123abc567xy"
echo "Please enter your OpenStack Password: "
read -sr OS_PASSWORD_INPUT
export OS_PASSWORD=$OS_PASSWORD_INPUT
export OS_REGION_NAME="SBG1"
if [ -z "$OS_REGION_NAME" ]; then unset OS_REGION_NAME; fi
The config file needs to look something like this where $OS_USERNAME represents the value
of the OS_USERNAME variable - 123abc567xy in the example above.
[remote]
type = swift
user = $OS_USERNAME
key = $OS_PASSWORD
auth = $OS_AUTH_URL
tenant = $OS_TENANT_NAME
Note that you may (or may not) need to set region too - try without first.
Specific options
Here are the command line options specific to this cloud storage system.
--swift-chunk-size=SIZE
Above this size files will be chunked into a _segments container. The default for this is
5GB which is its maximum value.
Modified time
The modified time is stored as metadata on the object as X-Object-Meta-Mtime as floating
point since the epoch accurate to 1 ns.
This is a defacto standard (used in the official python-swiftclient amongst others) for
storing the modification time for an object.
Limitations
The Swift API doesn't return a correct MD5SUM for segmented files (Dynamic or Static Large
Objects) so rclone won't check or use the MD5SUM for these.
Troubleshooting
Rclone gives Failed to create file system for remote: : Bad Request
Due to an oddity of the underlying swift library, it gives a "Bad Request" error rather
than a more sensible error when the authentication fails for Swift.
So this most likely means your username / password is wrong. You can investigate further
with the --dump-bodies flag.
This may also be caused by specifying the region when you shouldn't have (eg OVH).
Rclone gives Failed to create file system: Response didn't have
storage storage url and auth token
This is most likely caused by forgetting to specify your tenant when setting up a swift
remote.
Dropbox
Paths are specified as remote:path
Dropbox paths may be as deep as required, eg remote:directory/subdirectory.
The initial setup for dropbox involves getting a token from Dropbox which you need to do
in your browser. rclone config walks you through it.
Here is an example of how to make a remote called remote. First run:

You can then use it like this,
List directories in top level of your dropbox
rclone lsd remote:
List all the files in your dropbox
rclone ls remote:
To copy a local directory to a dropbox directory called backup
rclone copy /home/source remote:backup
Modified time and MD5SUMs
Dropbox doesn't provide the ability to set modification times in the V1 public API, so
rclone can't support modified time with Dropbox.
This may change in the future - see these issues for details:
• Dropbox V2 API (https://github.com/ncw/rclone/issues/349)
• Allow syncs for remotes that can't set modtime on existing objects
(https://github.com/ncw/rclone/issues/348)
Dropbox doesn't return any sort of checksum (MD5 or SHA1).
Together that means that syncs to dropbox will effectively have the --size-only flag set.
Specific options
Here are the command line options specific to this cloud storage system.
--dropbox-chunk-size=SIZE
Upload chunk size. Max 150M. The default is 128MB. Note that this isn't buffered into
memory.
Limitations
Note that Dropbox is case insensitive so you can't have a file called "Hello.doc" and one
called "hello.doc".
There are some file names such as thumbs.db which Dropbox can't store. There is a full
list of them in the "Ignored Files" section of this document
(https://www.dropbox.com/en/help/145). Rclone will issue an error message
File name disallowed - not uploading if it attempt to upload one of those file names, but
the sync won't fail.
If you have more than 10,000 files in a directory then rclone purge dropbox:dir will
return the error Failed to purge: There are too many files involved in this operation. As
a work-around do an rclone delete dropbix:dir followed by an rclone rmdir dropbox:dir.
Google Cloud Storage
Paths are specified as remote:bucket (or remote: for the lsd command.) You may put
subdirectories in too, eg remote:bucket/path/to/dir.
The initial setup for google cloud storage involves getting a token from Google Cloud
Storage which you need to do in your browser. rclone config walks you through it.

rclone sync /home/local/directory remote:bucket
Service Account support
You can set up rclone with Google Cloud Storage in an unattended mode, i.e. not tied to a
specific end-user Google account. This is useful when you want to synchronise files onto
machines that don't have actively logged-in users, for example build machines.
To get credentials for Google Cloud Platform IAM Service Accounts
(https://cloud.google.com/iam/docs/service-accounts), please head to the Service Account
(https://console.cloud.google.com/permissions/serviceaccounts) section of the Google
Developer Console. Service Accounts behave just like normal User permissions in Google
Cloud Storage ACLs (https://cloud.google.com/storage/docs/access-control), so you can
limit their access (e.g. make them read only). After creating an account, a JSON file
containing the Service Account's credentials will be downloaded onto your machines. These
credentials are what rclone will use for authentication.
To use a Service Account instead of OAuth2 token flow, enter the path to your Service
Account credentials at the service_account_file prompt and rclone won't use the browser
based authentication flow.
Modified time
Google google cloud storage stores md5sums natively and rclone stores modification times
as metadata on the object, under the "mtime" key in RFC3339 format accurate to 1ns.
Amazon Drive
Paths are specified as remote:path
Paths may be as deep as required, eg remote:directory/subdirectory.

See the remote setup docs (http://rclone.org/remote_setup/) for how to set it up on a
machine with no Internet browser available.
Note that rclone runs a webserver on your local machine to collect the token as returned
from Amazon. This only runs from the moment it opens your browser to the moment you get
back the verification code. This is on http://127.0.0.1:53682/ and this it may require
you to unblock it temporarily if you are running a host firewall.
Once configured you can then use rclone like this,
List directories in top level of your Amazon Drive
rclone lsd remote:
List all the files in your Amazon Drive
rclone ls remote:
To copy a local directory to an Amazon Drive directory called backup
rclone copy /home/source remote:backup
Modified time and MD5SUMs
Amazon Drive doesn't allow modification times to be changed via the API so these won't be
accurate or used for syncing.
It does store MD5SUMs so for a more accurate sync, you can use the --checksum flag.
Deleting files
Any files you delete with rclone will end up in the trash. Amazon don't provide an API to
permanently delete files, nor to empty the trash, so you will have to do that with one of
Amazon's apps or via the Amazon Drive website. As of November 17, 2016, files are
automatically deleted by Amazon from the trash after 30 days.
Using with non .com Amazon accounts
Let's say you usually use amazon.co.uk. When you authenticate with rclone it will take
you to an amazon.com page to log in. Your amazon.co.uk email and password should work
here just fine.
Specific options
Here are the command line options specific to this cloud storage system.
--acd-templink-threshold=SIZE
Files this size or more will be downloaded via their tempLink. This is to work around a
problem with Amazon Drive which blocks downloads of files bigger than about 10GB. The
default for this is 9GB which shouldn't need to be changed.
To download files above this threshold, rclone requests a tempLink which downloads the
file through a temporary URL directly from the underlying S3 storage.
--acd-upload-wait-per-gb=TIME
Sometimes Amazon Drive gives an error when a file has been fully uploaded but the file
appears anyway after a little while. This happens sometimes for files over 1GB in size
and nearly every time for files bigger than 10GB. This parameter controls the time rclone
waits for the file to appear.
The default value for this parameter is 3 minutes per GB, so by default it will wait 3
minutes for every GB uploaded to see if the file appears.
You can disable this feature by setting it to 0. This may cause conflict errors as rclone
retries the failed upload but the file will most likely appear correctly eventually.
These values were determined empirically by observing lots of uploads of big files for a
range of file sizes.
Upload with the -v flag to see more info about what rclone is doing in this situation.
Limitations
Note that Amazon Drive is case insensitive so you can't have a file called "Hello.doc" and
one called "hello.doc".
Amazon Drive has rate limiting so you may notice errors in the sync (429 errors). rclone
will automatically retry the sync up to 3 times by default (see --retries flag) which
should hopefully work around this problem.
Amazon Drive has an internal limit of file sizes that can be uploaded to the service.
This limit is not officially published, but all files larger than this will fail.
At the time of writing (Jan 2016) is in the area of 50GB per file. This means that larger
files are likely to fail.
Unfortunately there is no way for rclone to see that this failure is because of file size,
so it will retry the operation, as any other failure. To avoid this problem, use
--max-size 50000M option to limit the maximum size of uploaded files. Note that
--max-size does not split files into segments, it only ignores files over this size.
Microsoft OneDrive
Paths are specified as remote:path
Paths may be as deep as required, eg remote:directory/subdirectory.
The initial setup for OneDrive involves getting a token from Microsoft which you need to
do in your browser. rclone config walks you through it.
Here is an example of how to make a remote called remote. First run:

See the remote setup docs (http://rclone.org/remote_setup/) for how to set it up on a
machine with no Internet browser available.
Note that rclone runs a webserver on your local machine to collect the token as returned
from Microsoft. This only runs from the moment it opens your browser to the moment you
get back the verification code. This is on http://127.0.0.1:53682/ and this it may
require you to unblock it temporarily if you are running a host firewall.
Once configured you can then use rclone like this,
List directories in top level of your OneDrive
rclone lsd remote:
List all the files in your OneDrive
rclone ls remote:
To copy a local directory to an OneDrive directory called backup
rclone copy /home/source remote:backup
Modified time and hashes
OneDrive allows modification times to be set on objects accurate to 1 second. These will
be used to detect whether objects need syncing or not.
One drive supports SHA1 type hashes, so you can use --checksum flag.
Deleting files
Any files you delete with rclone will end up in the trash. Microsoft doesn't provide an
API to permanently delete files, nor to empty the trash, so you will have to do that with
one of Microsoft's apps or via the OneDrive website.
Specific options
Here are the command line options specific to this cloud storage system.
--onedrive-chunk-size=SIZE
Above this size files will be chunked - must be multiple of 320k. The default is 10MB.
Note that the chunks will be buffered into memory.
--onedrive-upload-cutoff=SIZE
Cutoff for switching to chunked upload - must be <= 100MB. The default is 10MB.
Limitations
Note that OneDrive is case insensitive so you can't have a file called "Hello.doc" and one
called "hello.doc".
Rclone only supports your default OneDrive, and doesn't work with One Drive for business.
Both these issues may be fixed at some point depending on user demand!
There are quite a few characters that can't be in OneDrive file names. These can't occur
on Windows platforms, but on non-Windows platforms they are common. Rclone will map these
names to and from an identical looking unicode equivalent. For example if a file has a ?
in it will be mapped to ？ instead.
The largest allowed file size is 10GiB (10,737,418,240 bytes).
Hubic
Paths are specified as remote:path
Paths are specified as remote:container (or remote: for the lsd command.) You may put
subdirectories in too, eg remote:container/path/to/dir.
The initial setup for Hubic involves getting a token from Hubic which you need to do in
your browser. rclone config walks you through it.
Here is an example of how to make a remote called remote. First run:
rclone config
This will guide you through an interactive setup process:

rclone copy /home/source remote:backup
If you want the directory to be visible in the official Hubic browser, you need to copy
your files to the default directory
rclone copy /home/source remote:default/backup
Modified time
The modified time is stored as metadata on the object as X-Object-Meta-Mtime as floating
point since the epoch accurate to 1 ns.
This is a defacto standard (used in the official python-swiftclient amongst others) for
storing the modification time for an object.
Note that Hubic wraps the Swift backend, so most of the properties of are the same.
Limitations
This uses the normal OpenStack Swift mechanism to refresh the Swift API credentials and
ignores the expires field returned by the Hubic API.
The Swift API doesn't return a correct MD5SUM for segmented files (Dynamic or Static Large
Objects) so rclone won't check or use the MD5SUM for these.
Backblaze B2
B2 is Backblaze's cloud storage system (https://www.backblaze.com/b2/).
Paths are specified as remote:bucket (or remote: for the lsd command.) You may put
subdirectories in too, eg remote:bucket/path/to/dir.
Here is an example of making a b2 configuration. First run
rclone config
This will guide you through an interactive setup process. You will need your account

This remote is called remote and can now be used like this
See all buckets
rclone lsd remote:
Make a new bucket
rclone mkdir remote:bucket
List the contents of a bucket
rclone ls remote:bucket
Sync /home/local/directory to the remote bucket, deleting any excess files in the bucket.
rclone sync /home/local/directory remote:bucket
Modified time
The modified time is stored as metadata on the object as
X-Bz-Info-src_last_modified_millis as milliseconds since 1970-01-01 in the Backblaze
standard. Other tools should be able to use this as a modified time.
Modified times are used in syncing and are fully supported except in the case of updating
a modification time on an existing object. In this case the object will be uploaded again
as B2 doesn't have an API method to set the modification time independent of doing an
upload.
SHA1 checksums
The SHA1 checksums of the files are checked on upload and download and will be used in the
syncing process.
Large files which are uploaded in chunks will store their SHA1 on the object as
X-Bz-Info-large_file_sha1 as recommended by Backblaze.
Transfers
Backblaze recommends that you do lots of transfers simultaneously for maximum speed. In
tests from my SSD equipped laptop the optimum setting is about --transfers 32 though
higher numbers may be used for a slight speed improvement. The optimum number for you may
vary depending on your hardware, how big the files are, how much you want to load your
computer, etc. The default of --transfers 4 is definitely too low for Backblaze B2
though.
Note that uploading big files (bigger than 200 MB by default) will use a 96 MB RAM buffer
by default. There can be at most --transfers of these in use at any moment, so this sets
the upper limit on the memory used.
Versions
When rclone uploads a new version of a file it creates a new version of it
(https://www.backblaze.com/b2/docs/file_versions.html). Likewise when you delete a file,
the old version will still be available.
Old versions of files are visible using the --b2-versions flag.
If you wish to remove all the old versions then you can use the
rclone cleanup remote:bucket command which will delete all the old versions of files,
leaving the current ones intact. You can also supply a path and only old versions under
that path will be deleted, eg rclone cleanup remote:bucket/path/to/stuff.
When you purge a bucket, the current and the old versions will be deleted then the bucket
will be deleted.
However delete will cause the current versions of the files to become hidden old versions.
Here is a session showing the listing and and retreival of an old version followed by a
cleanup of the old versions.
Show current version and all the versions with --b2-versions flag.
$ rclone -q ls b2:cleanup-test
9 one.txt
$ rclone -q --b2-versions ls b2:cleanup-test
9 one.txt

16 one-v2016-07-04-141003-000.txt
15 one-v2016-07-02-155621-000.txt

$ rclone -q --b2-versions copy b2:cleanup-test/one-v2016-07-04-141003-000.txt /tmp
$ ls -l /tmp/one-v2016-07-04-141003-000.txt
-rw-rw-r-- 1 ncw ncw 16 Jul 2 17:46 /tmp/one-v2016-07-04-141003-000.txt
Clean up all the old versions and show that they've gone.
$ rclone -q cleanup b2:cleanup-test
$ rclone -q ls b2:cleanup-test
9 one.txt
$ rclone -q --b2-versions ls b2:cleanup-test
9 one.txt
Data usage
It is useful to know how many requests are sent to the server in different scenarios.
All copy commands send the following 4 requests:
/b2api/v1/b2_authorize_account
/b2api/v1/b2_create_bucket
/b2api/v1/b2_list_buckets
/b2api/v1/b2_list_file_names
The b2_list_file_names request will be sent once for every 1k files in the remote path,
providing the checksum and modification time of the listed files. As of version 1.33
issue #818 (https://github.com/ncw/rclone/issues/818) causes extra requests to be sent
when using B2 with Crypt. When a copy operation does not require any files to be
uploaded, no more requests will be sent.
Uploading files that do not require chunking, will send 2 requests per file upload:
/b2api/v1/b2_get_upload_url
/b2api/v1/b2_upload_file/
Uploading files requiring chunking, will send 2 requests (one each to start and finish the
upload) and another 2 requests for each chunk:
/b2api/v1/b2_start_large_file
/b2api/v1/b2_get_upload_part_url
/b2api/v1/b2_upload_part/
/b2api/v1/b2_finish_large_file
B2 with crypt
When using B2 with crypt files are encrypted into a temporary location and streamed from
there. This is required to calculate the encrypted file's checksum before beginning the
upload. On Windows the %TMPDIR% environment variable is used as the temporary location.
If the file requires chunking, both the chunking and encryption will take place in memory.
Specific options
Here are the command line options specific to this cloud storage system.
--b2-chunk-size valuee=SIZE
When uploading large files chunk the file into this size. Note that these chunks are
buffered in memory and there might a maximum of --transfers chunks in progress at once.
100,000,000 Bytes is the minimim size (default 96M).
--b2-upload-cutoff=SIZE
Cutoff for switching to chunked upload (default 190.735 MiB == 200 MB). Files above this
size will be uploaded in chunks of --b2-chunk-size.
This value should be set no larger than 4.657GiB (== 5GB) as this is the largest file size
that can be uploaded.
--b2-test-mode=FLAG
This is for debugging purposes only.
Setting FLAG to one of the strings below will cause b2 to return specific errors for
debugging purposes.
• fail_some_uploads
• expire_some_account_authorization_tokens
• force_cap_exceeded
These will be set in the X-Bz-Test-Mode header which is documented in the b2 integrations
checklist (https://www.backblaze.com/b2/docs/integration_checklist.html).
--b2-versions
When set rclone will show and act on older versions of files. For example
Listing without --b2-versions
$ rclone -q ls b2:cleanup-test
9 one.txt
And with
$ rclone -q --b2-versions ls b2:cleanup-test
9 one.txt
8 one-v2016-07-04-141032-000.txt
16 one-v2016-07-04-141003-000.txt
15 one-v2016-07-02-155621-000.txt
Showing that the current version is unchanged but older versions can be seen. These have
the UTC date that they were uploaded to the server to the nearest millisecond appended to
them.
Note that when using --b2-versions no file write operations are permitted, so you can't
upload files or delete them.
Yandex Disk
Yandex Disk (https://disk.yandex.com) is a cloud storage solution created by Yandex
(http://yandex.com).
Yandex paths may be as deep as required, eg remote:directory/subdirectory.
Here is an example of making a yandex configuration. First run

See the remote setup docs (http://rclone.org/remote_setup/) for how to set it up on a
machine with no Internet browser available.
Note that rclone runs a webserver on your local machine to collect the token as returned
from Yandex Disk. This only runs from the moment it opens your browser to the moment you
get back the verification code. This is on http://127.0.0.1:53682/ and this it may
require you to unblock it temporarily if you are running a host firewall.
Once configured you can then use rclone like this,
See top level directories
rclone lsd remote:
Make a new directory
rclone mkdir remote:directory
List the contents of a directory
rclone ls remote:directory
Sync /home/local/directory to the remote path, deleting any excess files in the path.
rclone sync /home/local/directory remote:directory
Modified time
Modified times are supported and are stored accurate to 1 ns in custom metadata called
rclone_modified in RFC3339 with nanoseconds format.
MD5 checksums
MD5 checksums are natively supported by Yandex Disk.
SFTP
SFTP is the Secure (or SSH) File Transfer Protocol
(https://en.wikipedia.org/wiki/SSH_File_Transfer_Protocol).
It runs over SSH v2 and is standard with most modern SSH installations.
Paths are specified as remote:path. If the path does not begin with a / it is relative to
the home directory of the user. An empty path remote: refers to the users home directory.
Here is an example of making a SFTP configuration. First run
rclone config
This will guide you through an interactive setup process. You will need your account
number (a short hex number) and key (a long hex number) which you can get from the SFTP
control panel.

List the contents of a directory
rclone ls remote:path/to/directory
Sync /home/local/directory to the remote directory, deleting any excess files in the
directory.
rclone sync /home/local/directory remote:directory
Modified time
Modified times are stored on the server to 1 second precision.
Modified times are used in syncing and are fully supported.
Limitations
SFTP does not support any checksums.
SFTP isn't supported under plan9 until this issue (https://github.com/pkg/sftp/issues/156)
is fixed.
Note that since SFTP isn't HTTP based the following flags don't work with it:
--dump-headers, --dump-bodies, --dump-auth
Note that --timeout isn't supported (but --contimeout is).
Crypt
The crypt remote encrypts and decrypts another remote.
To use it first set up the underlying remote following the config instructions for that
remote. You can also use a local pathname instead of a remote which will encrypt and
decrypt from that directory which might be useful for encrypting onto a USB stick for
example.
First check your chosen remote is working - we'll call it remote:path in these docs. Note
that anything inside remote:path will be encrypted and anything outside won't. This means
that if you are using a bucket based remote (eg S3, B2, swift) then you should probably
put the bucket in the remote s3:bucket. If you just use s3: then rclone will make
encrypted bucket names too (if using file name encryption) which may or may not be what
you want.
Now configure crypt using rclone config. We will call this one secret to differentiate it
from the remote.

Important The password is stored in the config file is lightly obscured so it isn't
immediately obvious what it is. It is in no way secure unless you use config file
encryption.
A long passphrase is recommended, or you can use a random one. Note that if you
reconfigure rclone with the same passwords/passphrases elsewhere it will be compatible -
all the secrets used are derived from those two passwords/passphrases.
Note that rclone does not encrypt
• file length - this can be calcuated within 16 bytes
• modification time - used for syncing
Specifying the remote
In normal use, make sure the remote has a : in. If you specify the remote without a :
then rclone will use a local directory of that name. So if you use a remote of
/path/to/secret/files then rclone will encrypt stuff to that directory. If you use a
remote of name then rclone will put files in a directory called name in the current
directory.
If you specify the remote as remote:path/to/dir then rclone will store encrypted files in
path/to/dir on the remote. If you are using file name encryption, then when you save
files to secret:subdir/subfile this will store them in the unencrypted path path/to/dir
but the subdir/subpath bit will be encrypted.
Note that unless you want encrypted bucket names (which are difficult to manage because
you won't know what directory they represent in web interfaces etc), you should probably
specify a bucket, eg remote:secretbucket when using bucket based remotes such as S3,
Swift, Hubic, B2, GCS.
Example
To test I made a little directory of files using "standard" file name encryption.
plaintext/
├── file0.txt
├── file1.txt
└── subdir
├── file2.txt
├── file3.txt
└── subsubdir
└── file4.txt
Copy these to the remote and list them back
$ rclone -q copy plaintext secret:
$ rclone -q ls secret:
7 file1.txt
6 file0.txt
8 subdir/file2.txt
10 subdir/subsubdir/file4.txt
9 subdir/file3.txt
Now see what that looked like when encrypted
$ rclone -q ls remote:path
55 hagjclgavj2mbiqm6u6cnjjqcg
54 v05749mltvv1tf4onltun46gls
57 86vhrsv86mpbtd3a0akjuqslj8/dlj7fkq4kdq72emafg7a7s41uo
58 86vhrsv86mpbtd3a0akjuqslj8/7uu829995du6o42n32otfhjqp4/b9pausrfansjth5ob3jkdqd4lc
56 86vhrsv86mpbtd3a0akjuqslj8/8njh1sk437gttmep3p70g81aps
Note that this retains the directory structure which means you can do this
$ rclone -q ls secret:subdir
8 file2.txt
9 file3.txt
10 subsubdir/file4.txt
If don't use file name encryption then the remote will look like this - note the .bin
extensions added to prevent the cloud provider attempting to interpret the data.
$ rclone -q ls remote:path
54 file0.txt.bin
57 subdir/file3.txt.bin
56 subdir/file2.txt.bin
58 subdir/subsubdir/file4.txt.bin
55 file1.txt.bin
File name encryption modes
Here are some of the features of the file name encryption modes
Off
• doesn't hide file names or directory structure
• allows for longer file names (~246 characters)
• can use sub paths and copy single files
Standard
• file names encrypted
• file names can't be as long (~156 characters)
• can use sub paths and copy single files
• directory structure visibile
• identical files names will have identical uploaded names
• can use shortcuts to shorten the directory recursion
Cloud storage systems have various limits on file name length and total path length which
you are more likely to hit using "Standard" file name encryption. If you keep your file
names to below 156 characters in length then you should be OK on all providers.
There may be an even more secure file name encryption mode in the future which will
address the long file name problem.
Modified time and hashes
Crypt stores modification times using the underlying remote so support depends on that.
Hashes are not stored for crypt. However the data integrity is protected by an extremely
strong crypto authenticator.
Note that you should use the rclone cryptcheck command to check the integrity of a crypted
remote instead of rclone check which can't check the checksums properly.
Specific options
Here are the command line options specific to this cloud storage system.
--crypt-show-mapping
If this flag is set then for each file that the remote is asked to list, it will log (at
level INFO) a line stating the decrypted file name and the encrypted file name.
This is so you can work out which encrypted names are which decrypted names just in case
you need to do something with the encrypted file names, or for debugging purposes.
Backing up a crypted remote
If you wish to backup a crypted remote, it it recommended that you use rclone sync on the
encrypted files, and make sure the passwords are the same in the new encrypted remote.
This will have the following advantages
• rclone sync will check the checksums while copying
• you can use rclone check between the encrypted remotes
• you don't decrypt and encrypt unecessarily
For example, let's say you have your original remote at remote: with the encrypted version
at eremote: with path remote:crypt. You would then set up the new remote remote2: and
then the encrypted version eremote2: with path remote2:crypt using the same passwords as
eremote:.
To sync the two remotes you would do
rclone sync remote:crypt remote2:crypt
And to check the integrity you would do
rclone check remote:crypt remote2:crypt
File formats
File encryption
Files are encrypted 1:1 source file to destination object. The file has a header and is
divided into chunks.
Header
• 8 bytes magic string RCLONE\x00\x00
• 24 bytes Nonce (IV)
The initial nonce is generated from the operating systems crypto strong random number
genrator. The nonce is incremented for each chunk read making sure each nonce is unique
for each block written. The chance of a nonce being re-used is minuscule. If you wrote
an exabyte of data (10¹⁸ bytes) you would have a probability of approximately 2×10⁻³² of
re-using a nonce.
Chunk
Each chunk will contain 64kB of data, except for the last one which may have less data.
The data chunk is in standard NACL secretbox format. Secretbox uses XSalsa20 and Poly1305
to encrypt and authenticate messages.
Each chunk contains:
• 16 Bytes of Poly1305 authenticator
• 1 - 65536 bytes XSalsa20 encrypted data
64k chunk size was chosen as the best performing chunk size (the authenticator takes too
much time below this and the performance drops off due to cache effects above this). Note
that these chunks are buffered in memory so they can't be too big.
This uses a 32 byte (256 bit key) key derived from the user password.
Examples
1 byte file will encrypt to
• 32 bytes header
• 17 bytes data chunk
49 bytes total
1MB (1048576 bytes) file will encrypt to
• 32 bytes header
• 16 chunks of 65568 bytes
1049120 bytes total (a 0.05% overhead). This is the overhead for big files.
Name encryption
File names are encrypted segment by segment - the path is broken up into / separated
strings and these are encrypted individually.
File segments are padded using using PKCS#7 to a multiple of 16 bytes before encryption.
They are then encrypted with EME using AES with 256 bit key. EME (ECB-Mix-ECB) is a
wide-block encryption mode presented in the 2003 paper "A Parallelizable Enciphering Mode"
by Halevi and Rogaway.
This makes for deterministic encryption which is what we want - the same filename must
encrypt to the same thing otherwise we can't find it on the cloud storage system.
This means that
• filenames with the same name will encrypt the same
• filenames which start the same won't have a common prefix
This uses a 32 byte key (256 bits) and a 16 byte (128 bits) IV both of which are derived
from the user password.
After encryption they are written out using a modified version of standard base32 encoding
as described in RFC4648. The standard encoding is modified in two ways:
• it becomes lower case (no-one likes upper case filenames!)
• we strip the padding character =
base32 is used rather than the more efficient base64 so rclone can be used on case
insensitive remotes (eg Windows, Amazon Drive).
Key derivation
Rclone uses scrypt with parameters N=16384, r=8, p=1 with a an optional user supplied salt
(password2) to derive the 32+32+16 = 80 bytes of key material required. If the user
doesn't supply a salt then rclone uses an internal one.
scrypt makes it impractical to mount a dictionary attack on rclone encrypted data. For
full protection against this you should always use a salt.
Local Filesystem
Local paths are specified as normal filesystem paths, eg /path/to/wherever, so
rclone sync /home/source /tmp/destination
Will sync /home/source to /tmp/destination
These can be configured into the config file for consistencies sake, but it is probably
easier not to.
Modified time
Rclone reads and writes the modified time using an accuracy determined by the OS.
Typically this is 1ns on Linux, 10 ns on Windows and 1 Second on OS X.
Filenames
Filenames are expected to be encoded in UTF-8 on disk. This is the normal case for
Windows and OS X.
There is a bit more uncertainty in the Linux world, but new distributions will have UTF-8
encoded files names. If you are using an old Linux filesystem with non UTF-8 file names
(eg latin1) then you can use the convmv tool to convert the filesystem to UTF-8. This
tool is available in most distributions' package managers.
If an invalid (non-UTF8) filename is read, the invalid caracters will be replaced with the
unicode replacement character, '�'. rclone will emit a debug message in this case (use -v
to see), eg
Local file system at .: Replacing invalid UTF-8 characters in "gro\xdf"
Long paths on Windows
Rclone handles long paths automatically, by converting all paths to long UNC paths
(https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx#maxpath)
which allows paths up to 32,767 characters.
This is why you will see that your paths, for instance c:\files is converted to the UNC
path \\?\c:\files in the output, and \\server\share is converted to \\?\UNC\server\share.
However, in rare cases this may cause problems with buggy file system drivers like EncFS
(https://github.com/ncw/rclone/issues/261). To disable UNC conversion globally, add this
to your .rclone.conf file:
[local]
nounc = true
If you want to selectively disable UNC, you can add it to a separate entry like this:
[nounc]
type = local
nounc = true
And use rclone like this:
rclone copy c:\src nounc:z:\dst
This will use UNC paths on c:\src but not on z:\dst. Of course this will cause problems
if the absolute path length of a file exceeds 258 characters on z, so only use this option
if you have to.
Specific options
Here are the command line options specific to local storage
--copy-links, -L
Normally rclone will ignore symlinks or junction points (which behave like symlinks under
Windows).
If you supply this flag then rclone will follow the symlink and copy the pointed to file
or directory.
This flag applies to all commands.
For example, supposing you have a directory structure like this
$ tree /tmp/a
/tmp/a
├── b -> ../b
├── expected -> ../expected
├── one
└── two
└── three
Then you can see the difference with and without the flag like this
$ rclone ls /tmp/a
6 one
6 two/three
and
$ rclone -L ls /tmp/a
4174 expected
6 one
6 two/three
6 b/two
6 b/one
--one-file-system, -x
This tells rclone to stay in the filesystem specified by the root and not to recurse into
different file systems.
For example if you have a directory heirachy like this
root
├── disk1 - disk1 mounted on the root
│ └── file3 - stored on disk1
├── disk2 - disk2 mounted on the root
│ └── file4 - stored on disk12
├── file1 - stored on the root disk
└── file2 - stored on the root disk
Using rclone --one-file-system copy root remote: will only copy file1 and file2. Eg
$ rclone -q --one-file-system ls root
0 file1
0 file2
$ rclone -q ls root
0 disk1/file3
0 disk2/file4
0 file1
0 file2
NB Rclone (like most unix tools such as du, rsync and tar) treats a bind mount to the same
device as being on the same filesystem.
NB This flag is only available on Unix based systems. On systems where it isn't supported
(eg Windows) it will not appear as an valid flag.

Bugs and Limitations
Empty directories are left behind / not created
With remotes that have a concept of directory, eg Local and Drive, empty directories may
be left behind, or not created when one was expected.
This is because rclone doesn't have a concept of a directory - it only works on objects.
Most of the object storage systems can't actually store a directory so there is nowhere
for rclone to store anything about directories.
You can work round this to some extent with thepurge command which will delete everything
under the path, inluding empty directories.
This may be fixed at some point in Issue #100 (https://github.com/ncw/rclone/issues/100)
Directory timestamps aren't preserved
For the same reason as the above, rclone doesn't have a concept of a directory - it only
works on objects, therefore it can't preserve the timestamps of directories.
Frequently Asked Questions
Do all cloud storage systems support all rclone commands
Yes they do. All the rclone commands (eg sync, copy etc) will work on all the remote
storage systems.
Can I copy the config from one machine to another
Sure! Rclone stores all of its config in a single file. If you want to find this file,
the simplest way is to run rclone -h and look at the help for the --config flag which will
tell you where it is.
See the remote setup docs (http://rclone.org/remote_setup/) for more info.
How do I configure rclone on a remote / headless box with no
browser?
This has now been documented in its own remote setup page
(http://rclone.org/remote_setup/).
Can rclone sync directly from drive to s3
Rclone can sync between two remote cloud storage systems just fine.
Note that it effectively downloads the file and uploads it again, so the node running
rclone would need to have lots of bandwidth.
The syncs would be incremental (on a file by file basis).
Eg
rclone sync drive:Folder s3:bucket
Using rclone from multiple locations at the same time
You can use rclone from multiple places at the same time if you choose different
subdirectory for the output, eg
Server A> rclone sync /tmp/whatever remote:ServerA
Server B> rclone sync /tmp/whatever remote:ServerB
If you sync to the same directory then you should use rclone copy otherwise the two
rclones may delete each others files, eg
Server A> rclone copy /tmp/whatever remote:Backup
Server B> rclone copy /tmp/whatever remote:Backup
The file names you upload from Server A and Server B should be different in this case,
otherwise some file systems (eg Drive) may make duplicates.
Why doesn't rclone support partial transfers / binary diffs like
rsync?
Rclone stores each file you transfer as a native object on the remote cloud storage
system. This means that you can see the files you upload as expected using alternative
access methods (eg using the Google Drive web interface). There is a 1:1 mapping between
files on your hard disk and objects created in the cloud storage system.
Cloud storage systems (at least none I've come across yet) don't support partially
uploading an object. You can't take an existing object, and change some bytes in the
middle of it.
It would be possible to make a sync system which stored binary diffs instead of whole
objects like rclone does, but that would break the 1:1 mapping of files on your hard disk
to objects in the remote cloud storage system.
All the cloud storage systems support partial downloads of content, so it would be
possible to make partial downloads work. However to make this work efficiently this would
require storing a significant amount of metadata, which breaks the desired 1:1 mapping of
files to objects.
Can rclone do bi-directional sync?
No, not at present. rclone only does uni-directional sync from A -> B. It may do in the
future though since it has all the primitives - it just requires writing the algorithm to
do it.
Can I use rclone with an HTTP proxy?
Yes. rclone will use the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY,
similar to cURL and other programs.
HTTPS_PROXY takes precedence over HTTP_PROXY for https requests.
The environment values may be either a complete URL or a "host[:port]", in which case the
"http" scheme is assumed.
The NO_PROXY allows you to disable the proxy for specific hosts. Hosts must be comma
separated, and can contain domains or parts. For instance "foo.com" also matches
"bar.foo.com".
Rclone gives x509: failed to load system roots and no roots provided
error
This means that rclone can't file the SSL root certificates. Likely you are running
rclone on a NAS with a cut-down Linux OS, or possibly on Solaris.
Rclone (via the Go runtime) tries to load the root certificates from these places on
Linux.
"/etc/ssl/certs/ca-certificates.crt", // Debian/Ubuntu/Gentoo etc.
"/etc/pki/tls/certs/ca-bundle.crt", // Fedora/RHEL
"/etc/ssl/ca-bundle.pem", // OpenSUSE
"/etc/pki/tls/cacert.pem", // OpenELEC
So doing something like this should fix the problem. It also sets the time which is
important for SSL to work properly.
mkdir -p /etc/ssl/certs/
curl -o /etc/ssl/certs/ca-certificates.crt https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt
ntpclient -s -h pool.ntp.org
Note that you may need to add the --insecure option to the curl command line if it doesn't
work without.
curl --insecure -o /etc/ssl/certs/ca-certificates.crt https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt
Rclone gives Failed to load config file: function not implemented
error
Likely this means that you are running rclone on Linux version not supported by the go
runtime, ie earlier than version 2.6.23.
See the system requirements section in the go install docs
(https://golang.org/doc/install) for full details.
All my uploaded docx/xlsx/pptx files appear as archive/zip
This is caused by uploading these files from a Windows computer which hasn't got the
Microsoft Office suite installed. The easiest way to fix is to install the Word viewer
and the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 and later
versions' file formats
