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)

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

          --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

          --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).

          --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

          --upstart
                 Stay in foreground and raise SIGSTOP once mountpoint is up.

          --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

          --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)
