Re: Fwd: Bacula: Backup Fatal Error of Client:qnap-data Fileset:qnap-data Differential

We probably aren't able to test this because you have purged the relevant
jobs, but I would have been curious to see what a data verify job would
have found. Perhaps the original backup job was corrupted in the volume
somewhere? This is only a guess, and not an informed experience-based
supposition.
