It was removed because it was fatally flawed for simultaneous backups. I suppose it could work for restore during a backup. > I can imagine, that the whole catalog must be locked.

Having a separate catalog would work, but you would need to schedule a time to copy from one to the other. > I there a chance, that this problem went away with an update to the > latest 2.2.x version of bacula? > > A little kick in the right direction would be very appreciated! What indexes does your catalog have? Maybe it is missing one that would make the tree building run faster? Have you considered splitting the fileset into several smaller filesets? If you have lots of data that never changes much, then that could be backed up less often. __Martin ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
