That's weird. And I thought I had serious database issues! :) Of course I am
running a daily db-backup, wouldn't want to live without it, but other than
for a backup gone wrong I had never had to recover the bacula database in the
last year and a half.
Actually Ian should be able to happily restore jobs even after 11 months and
some 30 days, because of his volume retention. If he actually has that many
volumes to cycle through before having to recycle (and the volumes don't turn
bad due to heavy sun or heat exposure or such a thing) he should still be
able to run a bscan or even restore directly using a bootstrap file. No
database involved here as far as I can tell.

Same disks here, same tapes, same library. Seriously, if that SL500 downstairs
explodes or something I will really have more serious problems than the
catalog. As long as all the tapes are intact, I could probably lock myself in
for a week and restore the catalog almost completely.

I used to run the catalog backups onto our bacula test environment. It's not
fast, but it sure is somewhat "off-site" :)
