Hi Andrey,

As of v5.2.x, you have the ability to specify any jobid to be verified on the
command line. From the v5.2.1 main.pdf manual:

----8<----
New Features in 5.2.x
3.6 Ability to Verify any specified Job

You now have the ability to tell Bacula which Job should verify instead of
automatically verify just the last one.

This feature can be used with VolumeToCatalog, DiskToCatalog and Catalog level.

To verify a given job, just specify the Job jobid in argument when starting
the job.

* run job=VerifyVolume jobid=1 level=VolumeToCatalog
----8<----

So, if you really wanted to periodically check (a|any|random) Bacula file
volume(s) you could easily script it by piping such a run command to bconsole
with the required jobid.

Hope this helps.

Bill
