Hi - I've been evaluating Bacula for a while now, and I'm getting set to transition from Amanda to Bacula. I'm backing up 17 hosts (Linux and Tru64 Unix), currently to a 26 tape TL-891 (DLT-IV) library. I've got my new tape drive in (30 tape MSL6030 with an Ultrium-2), and for the last week or so, I've been running backups of several hosts with Bacula to test everything. I'm running full dumps every night, since I wanted to test spanning tapes and the autochanger.
One thing that I'm concerned with is that it seems that the 'sending spool attrs to the director' step, which I understand is inserting/ updating attributes in the database, takes a VERY long time. I'm using a PostgreSQL database, and the director and storage daemon are on the same host (asclbackup).
Below is a backup report - first of all, am I reading this right? It looks to me like the actual backup is finished by around 22:42 (data actually transferred to asclbackup by 21:15, and then another 1.5 hours or so to dump it to tape), and then the next 8 hours are spent dealing with the attributes. I'd really like to be able to speed that up a bit...
On the up side, the MSL6030 library works perfectly with bacula.
Any ideas are appreciated...if you need config files to look at, the sd and dir conf files are at:

with passwords taken out, of course :-)
