Well, ordinarily, my selection criteria looks like:
-q "client=%machine%,volume=%tapevol%,copies>2,savetime<1 day 17:00"
Which *should* give me any savesets that have been cloned to tape (3
copies = 1 on RW disk, 1 on RO disk, 1 on tape), and that were created
before 5PM yesterday (in our case, that effectively means 2 days ago). We
then delete those returned savesets.
This particluar script is for a machine that doesn't have enough diskspace
to keep 1 day's backup on disk, so this script clears out everything on
the disk space.

Hrm ... so I should be adding "clflags <> a"?
