Sorry for the delayed response, I was on vacation.
That was just an overview. Each Job is tied to a single client. I
haven't been able to get this working properly yet; the lower priority
jobs always "multiplex" (to use a NetBackup term) concurrently and force
the higher priority job to wait.
I wonder if using Migration would be more appropriate. I can create a
File Storage device and have the higher priority jobs use that for
Migration, then use tape volumes for the Next Pool. Does this sound
reasonable?
Thanks,
