Thanks Randy,
Unfortunately Maximum Concurrent Jobs won't cut it because I need a different tape per client. Still I set it to 1000.
When spooling is enabled, bacula still wants a tape from the client pool on the drive before the spooling starts.
I could create a virtual library with MHVTL and use several drives or use a disk-changer emulator. But I am not sure how scalable these solutions are.

I have a setup to backup lots of clients over

I want to have each client (or group of clients) backed up to
dedicated client pools, so client1 will go to pool client1, and
so on.
That way I have better control of the space used, if a client
goes away I can simply delete the tapes (or files) an get the
space back immediately.
Also it gives me better control on the retention on a per client
basis.
The problem is that when I try to backup multiple clients at the
same time, the storage process has to wait for each job to
finish before it can move to the next because it needs to change
the tape (different client --> different pool). Some clients
may take many hours to finish, forcing everybody else to wait.
I enabled spooling, but it seems like Bacula requires to mount a
tape from the client pool on a drive before the client spooling
can begin.
Can this be avoided?
A possible solution would be to do all backups on a special pool
and after they are done migrate later each client job to each
client pool.
But I cannot find a way to modify the "Next Pool" dynamically.
It is a fixed setting on the Pool definition.
Does anybody have suggestions on how to accomplish this?
Look into Maximum Concurrent Jobs in your Storage definition.
Regards,
Randy
