No, I have never seen anything like this. And this is from a bacula
user for 8+ years who has run tens of thousands of backups for a
department with 50+ machines and 30 to 50TB on tape. I suggest you
examine what bacula has saved in the backup. The simplest way is to
use the bat version browser or the new restore viewer if you have
bacula-5.2.X.
