the problem is, that the data isn't in the catalog anymore. it got pruned
after 6 months. the client limit was accidentially set to this value...
also see my bls comment below.
but just thought about it, and there has to be a backup from the catalog.
where the ARCHIVE-0000 volume is still available with file entries.

yeah, better loose 16GB than 1,3TB. :)

problem: the tape drive doesn't go over file 4, it's running in circles
telling me that it skipped a block but next message telling me again that
the same block is beeing skipped (and so on).
if i do an "mt fsf 5" i need to rewind the tape to get access again, else
it will print i/o error.
so the bacula utilities won't give me a file list and restoring the whole
job doesn't work because of the defective area. sort of henn/egg problem.

think the feature is cirtical for users whose catalog entries got pruned,
no (maybe a really old one is needed) catalog backup is available and
the tape is not in a good state.
