Hi Sebastian,
I'm only a newbie to this but looking at your director config settings
it looks like you haven't expressed a maximum volume size. Therefore
Bacula will keep filling up a volume until your disk runs out. To force
Bacula to stop filling a volume and look around for another one you
should use a 'Maximum Volume Bytes = nnn' or 'Maximum Volume Jobs = nnn'
or 'Volume Use Duration = ttt' setting in your pools definition.
Re-read the beginning of Chapter 22 'Automatic Volume Recycling' for
more details.
Hope that helps.
Regards,
David Legg
