Hi,

If i use one volume for all job, how can i delete or remove data of one job. 
All data is stored in one file.

Well, I'd also want to look at the elevator scheduler and the actual
hardware too...

The problem as I see it, is bacula sucks at "disks as tapes". It doesn't
work without vchanger, and it can't auto-label volumes in the vchanger.
(Inability to write two copies at once to guard against disk failure is
icing on the cake.)

If you back up to a single filesystem, you can spool jobs in parallel to
fast drive and have them despooling to volumes sequentially to spinning
rust with very little practical speed penalty. Provided your disk
subsystem is faster than the network, of course. Adding one volume per
job/client constraint and $(JobId) to volume label shouldn't be too hard.

If you want to use removable drives as "magazines" with one drive per
client... I'd be tempted to take a close look at BackupPC or some such
before I'd commit to bacula.
