Hi all,
we startet using Bacula with a Neo400 ( incl. 2 LTO6 Drives ) for
backup. Although we have quit big amounts of data to backup the job
should be pretty simple since mostly it just needs to copy the files to
tapes for an off-site backup. Since we are using a zfs as file system
bacula has a relaxed time window of one week for the backup.
But we have one important point that is One Job per Volume ( so we can
take the tapes easily off site and back ). After some interesting
experiences with "purge jobs" our full backup as base for the
incremental was finally done:

There are on average ~ 2.8TB on every tape. Also when I query the jobs
for a tape I get two jobid 66 and 65 as result.
But when I get the details for the Volume via e.g. llist volume=RB0101L6
it says there is only one job on the volume and ther should be only one
job on the volume ... as far as I understand:
*llist volume=RB0101L6

Every Pool has the Maximum Volume Jobs = 1 set. I'll admit we are doing
lot of experimenting and purging but this option has always been set.
In total the amount of data wirtten to the Tapes / Job Size is matching
... more or less. But there are just to many Volumes per Job...
I am a little clueless here ... I would appreciate any hints.
With kind regards
