NAME

       s3ql_verify - Verify data in an S3QL file system

SYNOPSIS

          s3ql_verify [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 s3ql_verify command verifies all data in the file system.  In contrast to fsck.s3ql, s3ql_verify does
       not trust the object listing returned by the backend, but actually attempts to retrieve every object.  It
       therefore takes a lot longer.

       The  format  of  <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 s3ql_verify 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: None

          --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

          --version
                 just print program version and exit

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

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

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

          --missing-file <name>
                 File to store keys of missing objects.

          --corrupted-file <name>
                 File to store keys of corrupted objects.

          --data Read every object completely, instead of checking just the metadata.

          --parallel PARALLEL
                 Number of connections to use in parallel.

          --start-with <n>
                 Skip over first <n> objects and with verifying object <n>+1.
