[Bacula-users] It's possible to parallelize backups?

Hi at all,
since some weeks I got a new SCSI controller due to use a second tape
reader into the HP MSL6030 (a Overland NEO 2000 clone) tape library.
After some initially troubles and a some telephonic shout with HP
support, now I'm able to use both internal reader (nst0 and nst1) and to
control the autocharger (sg1).
Actually I've defined two test pools: IncrWeek and WinIncrWeek. My goal
is to get two simultaneous backups from two different client onto two
tapes, one for each pool.

The problem is that, when a job start gets the first drive ([0])
meanwhile the second job wait for first terminating, to use the same drive.

I've attached my sd.conf and my storage section, where's wrong?

Thanks for you time,

Simone
