Thanks Greg,
But I would still have the problem that I need a device tied up backing up each
client.
The problem I am facing is that I need to backup lots of slow clients, and I
need to come up with something so I can back them up all at the _same_ time on
one or maybe a few devices, and still have a Pool per client.

Hi Pablo,
If you have enough disk space handy, you could send each Client’s data to its
own disk Pool with its own Next Pool specification. Each Client’s data would be
in its own Pool on disk, then move to its own Pool on tape. This is exactly
what I’ve done at my site, except the disk Pools all point to the same tape
Pool.

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 slow links.
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
