When you define the copy storage pool, make sure you define it with the
collocation parameter set to no.  Then the storage pool will use the
fewest tapes possible.

Subject: Tape Copy pools and Colocation

Hello,

I'm starting to implement tape copy pools.  My primary pool has
colocation
enabled, in order to speed up restores.  My primary storage pool
currently
is using 27 tapes at varying degrees of usage.  When I did a test BACKUP
STGPOOL, the output indicated that it wanted to use another 27 tapes,
even
though that would end up leaving unused space on each tape.

I expect that the copy pool will not be used a whole lot;  I intend to
move these tapes out of the library after each backup, and as such,
prefer
density and tape efficiency to speed of recovery from these tapes.

I was wondering if there is a way to have it use the copy pool such that
it uses the fewest tapes possible, filling up each tape fully before
pulling another one from scratch.

Or, does it do this already, and is the test run just being
ultra-conservative?

Thanks,
