PROGRAM:
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.

The s3ql_verify command accepts the following options.
--debug-modules <modules>
