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.

          --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
