I suspect that you are confused about the difference in how Bacula handles
writing a tape and reading a tape. It is clear that the tape is damaged and
that Bacula cannot write on it without recycling the tape. However, it does
not appear you have tried to use Bacula to restore from the tape.
Suggestions:
- If you *really* need some data on the tape, try a restore and see what it
can salvage.
- Simply start using another tape for your appends, possibly redoing any saves
in progress during the power failure (as determined from the catalog). If
Bacula was writing the tape when the power outage occurred unless you are
very cleaver, it is not going to ever try to read from the Job/Jobs it was
writing.
