Hi everyone!

I was having to many problems working with one pool for each day of the 
week. So, recently, I reconfigure all my bacula director to use ten 
tapes with only one pool. It's working fine now. I don't have a tape 
library, so manual changes are done every day (except weekends). From 
Monday to Saturday, I run differential jobs. On Sunday, only full jobs. 
However, the Monday's tapes are doing the Saturday diff, Sunday full and 
Monday diff jobs. Obviously, I need more space for this. These three day 
tapes (the two Monday one's) aren't capable of doing more than one 
backup. So, every Friday I have the delete one of the Monday's volume 
and rewind the tape manually. I can't use Maximum Volume Jobs option. I 
tough in the Maximum Volume Bytes instead. The other tapes, I can handle 
for up to two or three months

My doubt is if that will work properly or not. For example: Maximum 
Volume Bytes is 150g. In one three day tape jobs, it consumes 140g. Next 
time the tape will be used, it will erase before passing the 150g or it 
will ask for a new tape when the job that overlaps the 150g ends? I need 
bacula to detect this proximity to the volume bytes limit and recycle 
the tape before having and error or asking for another volume.

Maybe I will have problems when a new holiday come-up, however, that 
will be another case to think and fix.

Any suggestions?

Thanks!

João K.
