NAME

       mount.s3ql - Mount an S3QL file system

SYNOPSIS

          mount.s3ql [options] <storage url> <mount point>

DESCRIPTION

       S3QL is a file system for online data storage. Before using S3QL, make sure to consult the
       full documentation (rather than just  the  man  pages  which  only  briefly  document  the
       available userspace commands).

       The  mount.s3ql command mounts the S3QL file system stored in storage url in the directory
       mount point. The storage url depends on the backend that is used. The  S3QL  User's  Guide
       should be consulted for a description of the available backends.

OPTIONS

       The mount.s3ql command accepts the following options.

          --log <target>
                 Destination for log messages. Specify none for standard output or syslog for the
                 system logging daemon. Anything else will be interpreted as  a  file  name.  Log
                 files will be rotated when they reach 1 MiB, and at most 5 old log files will be
                 kept. Default: ~/.s3ql/mount.log

          --cachedir <path>
                 Store cached data in this directory (default: ~/.s3ql)

          --debug-modules <modules>
                 Activate debugging  output  from  specified  modules  (use  commas  to  separate
                 multiple modules). Debug messages will be written to the target specified by the
                 --log option.

          --debug
                 Activate debugging output from all S3QL modules. Debug messages will be  written
                 to the target specified by the --log option.

          --quiet
                 be really quiet

          --backend-options <options>
                 Backend  specific  options  (separate  by commas). See backend documentation for
                 available options.

          --version
                 just print program version and exit

          --authfile <path>
                 Read authentication credentials from this file (default: ~/.s3ql/authinfo2)

          --compress <algorithm-lvl>
                 Compression algorithm and compression  level  to  use  when  storing  new  data.
                 algorithm  may be any of lzma, bzip2, zlib, or none. lvl may be any integer from
                 0 (fastest) to 9 (slowest). Default: lzma-6

          --cachesize <size>
                 Cache size in KiB (default: autodetect).

          --max-cache-entries <num>
                 Maximum number of entries in  cache  (default:  autodetect).  Each  cache  entry
                 requires  one  file  descriptor, so if you increase this number you have to make
                 sure that your process file descriptor limit (as set with  ulimit  -n)  is  high
                 enough (at least the number of cache entries + 100).

          --keep-cache
                 Do not purge locally cached files on exit.

          --allow-other
                 Normally,  only  the user who called mount.s3ql can access the mount point. This
                 user  then  also  has  full  access  to  it,  independent  of  individual   file
                 permissions.  If  the  --allow-other option is specified, other users can access
                 the mount point as well and individual file permissions are taken  into  account
                 for all users.

          --allow-root
                 Like --allow-other, but restrict access to the mounting user and the root user.

          --fg   Do not daemonize, stay in foreground

          --fs-name FS_NAME
                 Mount  name  passed  to  fuse, the name will be shown in the first column of the
                 system mount command output.  If not specified your storage url is used.

          --systemd
                 Run as systemd unit. Consider specifying --log none  as  well  to  make  use  of
                 journald.

          --metadata-upload-interval <seconds>
                 Interval  in  seconds  between  complete metadata uploads.  Set to 0 to disable.
                 Default: 24h.

          --threads <no>
                 Number of parallel upload threads to use (default: auto).

          --nfs  Enable some optimizations for exporting the  file  system  over  NFS.  (default:
                 False)
