There is one reason for this. A few years ago I had my bacula database
on a machine with a hardware problem. At one point my bacula database
became corrupt but I did not find out for a week or so since backups
merrily continued. When I detected the corruption a few weeks have
passed. So when I went to recover the database I had to keep going
back till I found a database that was good. The good thing is I
retained the boot strap files otherwise this would have been very
difficult. After finding the working database I recovered it on a new
machine and then used the bacula tools to recover the missing records.
I did that bu knowing which tapes were used in the period that the
database had been corrupted.
