Re: [Bacula-users] Reload Tapes using bscan
2014-12-30 03:00:11
Hello Christian,
If btape is saying that the volume is prelabeled, it means that it
has a Bacula label that is written *before* any data is put on the
tape. This means that either the tape was never written, or
someone (not Bacula) wrote an end of file mark at the beginning of
the tape, then the next time it was mounted by Bacula (or some sys
admin) Bacula recognized it as a "blank" tape and wrote a
prelabel.
It is very difficult to recover from a tape being overwritten, but
it is possible and rather complicated. It involves first scanning
the tape to see if there is any real data past the prelabel
records, and if so, copying the good data to another tape.
Best regards,
Kern

Maybe something from my bacula-sd.conf ?

Hello Christian,
Have you tried the recovery from tapes
without using the bootstrap file? It can be done this way:
./bscan -V TestVolume1 -v -s -m -c bacula-sd.conf /dev/nst0
And if have your backup in more than
one volume, you can try this way:
./bscan -V TestVolume1/|TestVolume2/|TestVolume3 -v -s -m -c bacula-sd.conf /dev/nst0
Maybe the bootstrap file that you have
created is missing something. I have been using bscan
without mentioning bootstrap files and It works fine for
me.
Best regards,
Ana
