NAME

       borgfs - Mount archive or an entire repository as a FUSE filesystem

SYNOPSIS

       borgfs [options] REPOSITORY_OR_ARCHIVE MOUNTPOINT [PATH...]

DESCRIPTION

       This  command  mounts  an archive as a FUSE filesystem. This can be useful for browsing an
       archive or restoring individual files. Unless the --foreground option is given the command
       will run in the background until the filesystem is umounted.

       The  command  borgfs  provides  a  wrapper  for borg mount. This can also be used in fstab
       entries: /path/to/repo /mnt/point fuse.borgfs defaults,noauto 0 0

       To allow a regular  user  to  use  fstab  entries,  add  the  user  option:  /path/to/repo
       /mnt/point fuse.borgfs defaults,noauto,user 0 0

       For FUSE configuration and mount options, see the mount.fuse(8) manual page.

       Borg's  default  behavior is to use the archived user and group names of each file and map
       them to the system's respective user and group ids.  Alternatively, using numeric-ids will
       instead use the archived user and group ids without any mapping.

       The  uid  and gid mount options (implemented by Borg) can be used to override the user and
       group ids of all files (i.e., borg mount -o uid=1000,gid=1000).

       The man page references user_id and group_id mount options  (implemented  by  fuse)  which
       specify the user and group id of the mount owner (aka, the user who does the mounting). It
       is set automatically by libfuse (or the filesystem if libfuse is not used).  However,  you
       should  not  specify these manually. Unlike the uid and gid mount options which affect all
       files, user_id and group_id affect the user and group id of the mounted (base) directory.

       Additional mount options supported by borg:

       • versions: when used with a repository mount, this gives a merged, versioned view of  the
         files in the archives. EXPERIMENTAL, layout may change in future.

       • allow_damaged_files:  by  default damaged files (where missing chunks were replaced with
         runs of zeros by borg check --repair) are not readable and return EIO (I/O  error).  Set
         this option to read such files.

       • ignore_permissions:  for  security  reasons  the  "default_permissions"  mount option is
         internally  enforced  by  borg.  "ignore_permissions"  can  be  given  to  not   enforce
         "default_permissions".

       The  BORG_MOUNT_DATA_CACHE_ENTRIES  environment  variable  is  meant for advanced users to
       tweak the performance. It sets the number of cached data chunks; additional  memory  usage
       can be up to ~8 MiB times this number. The default is the number of CPU cores.

       When the daemonized process receives a signal or crashes, it does not unmount.  Unmounting
       in these cases could cause an active rsync or similar process  to  unintentionally  delete
       data.

       When running in the foreground ^C/SIGINT unmounts cleanly, but other signals or crashes do
       not.

OPTIONS

       See borg-common(1) for common options of Borg commands.

   arguments
       REPOSITORY_OR_ARCHIVE
              repository or archive to mount

       MOUNTPOINT
              where to mount filesystem

       PATH   paths to extract; patterns are supported

   optional arguments
       -V, --version
              show version number and exit

       --consider-checkpoints
              Show checkpoint archives in the repository contents list (default: hidden).

       -f, --foreground
              stay in foreground, do not daemonize

       -o     Extra mount options

       --numeric-owner
              deprecated, use --numeric-ids instead

       --numeric-ids
              use numeric user and group identifiers from archive(s)

   Archive filters
       -P PREFIX, --prefix PREFIX
              only consider archive names starting with this prefix.

       -a GLOB, --glob-archives GLOB
              only consider archive names matching the glob. sh:  rules  apply,  see  "borg  help
              patterns". --prefix and --glob-archives are mutually exclusive.

       --sort-by KEYS
              Comma-separated  list of sorting keys; valid keys are: timestamp, name, id; default
              is: timestamp

       --first N
              consider first N archives after other filters were applied

       --last N
              consider last N archives after other filters were applied

   Exclusion options
       -e PATTERN, --exclude PATTERN
              exclude paths matching PATTERN

       --exclude-from EXCLUDEFILE
              read exclude patterns from EXCLUDEFILE, one per line

       --pattern PATTERN
              include/exclude paths matching PATTERN

       --patterns-from PATTERNFILE
              read include/exclude patterns from PATTERNFILE, one per line

       --strip-components NUMBER
              Remove the specified number of leading path elements.  Paths  with  fewer  elements
              will be silently skipped.
