Provided by: s3ql_3.3.2+dfsg-1ubuntu1_amd64

NAME

       fsck.s3ql - Check an S3QL file system for errors

SYNOPSIS

          fsck.s3ql [options] <storage url>

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  fsck.s3ql  command  checks  the  file system in the location specified by storage url for errors and
       attempts to repair any problems. 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 fsck.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/fsck.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

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

--batch
If user input is required, exit without prompting.

--force
Force checking even if file system is marked clean.

--force-remote
Force use of remote metadata even when this would likely result in data loss.
