Are you running "expiration" on a daily basis?

TSM 4.1.3 on NT 4, 2 LTO drives in IBM 18 tape library.  Single SCSI chain.

We run reclamation what seems like all day every day, but tapes don't
seem to free up in a timely manner.  And our offsite tapes are 'growing'.
We have been using TSM for about a year with 60 day retention, and have
only added two (small) clients in the last 2 months.

The pool for onsite TAPEPOOL (that stays in the library) and COPYPOOL
that goes off site.  The number of tapes in the COPYPOOL (offsite) seem to
be
growing greater than what would seem reasonable given the size of the
TAPEPOOL.

Lately I have stopped reclamation and done a 'move data' of some of the
lowest use volumes that are offsite, and now they are marked 'pending'.

Our current schedule is:
  Weekdays 1300 till 2000 - update stgpool COPYPOOL rec=20
  Weekdays 0900 till 1300 - update stgpool TAPEPOOL rec=10
  Saturday 0800 till 2000 - update stgpool TAPEPOOL rec=10
  Sunday 0800 till 2200 - update stgpool COPYPOOL rec=20

Would it be a good idea to up the recovery percent?

Should I possibly do copypool on MWF from 0900-2000 then
tapedata on TTh instead of some on each day?

Suggestions?

TIA .. JC
