Hi List

I have to (longtime) archive data on tape. To be sure that the data
which was written on tape is ok i'd like to run a verify job after the
successfull backup/archive job. The verify job should compare the data
of the source with the data written on tape to ensure the data is save
on tape before i may delete the source.

Is this somehow doable with bacula ?

It seams to me that the currently implemented "verify" option in bacula
will not read/verify data from tape but only compare checksums in the
catalog database; which is a fine feature but will not ensure that the
data on tape is ok.

Will the tape drive itself ensure that the data is verified during the
backup job (by a read-after-write verify)? I know tapes that have
multiple heads, one for write, one for the verification of the written
data. But is this valid for all tape drives ?
