Yeah, that works ... when you only need to control pools based on job level.

My problem is that sometimes I need to control other job attibutes, such
as spooling, by job level.

The mechanism just needs to be generalised a little, so your above
example becomes:


JobDefs {
  Name = Backup
  Type = Backup
  Level = Full
  Full {
    Pool = Full-Tape
  }
  Differential {
    Pool = Diff-Disk
  }
  Incremental {
    Pool = Incr-Disk
  }
  Schedule = "Monthly Rotation"
  [...]
}

... or something like that, so other things may be overridden based on
level.

OK, good to know. I was actually using this mechamism before, but
thought it selected the pool *before* making the promotion decision. In
any case I had to switch to schedule-based overrides due to another
issue with retention periods and manual backups that I'll mention once
I've written it up properly.
