Actually, you only do incrementals forever, so your daily and weekend
processing will be identical:

backup stg primary_pool copy_stg_pool

ADSM knows to only move the newly arrived data.

ADSM can reclaim copy storage pool volumes.  By default, the reclamation
threshold on copy stg's is 100, so no reclamation will occur.  I would
suggest setting the threshold down to 1 on the weekends and letting the
system generate new copy stg pool volumes.  You will then take these to the
off-site and return those volumes in the copy stg pool marked off-site,
empty to the on-site.  When you do this, after reusedelay has expired, ADSM
will scratch these volumes returning them to use.

Good analysis.  You are right.  Most of the tapes that go off-site are only
partially full and are probably reclamation candidates immediately.  One
could probably reclaim these tapes more often than weekly and actually get
the data from yesterday on today's tape before today's tape leaves.  You
might experiment with that, if you have enough time in your end-of-day
processing.

I don't think you would have been able to do a full backup weekly, unless
you deleted the copy stg pool volumes from the pool using a discarddata=yes
switch.
