in general, I want all expired media to return to scratch for ease of
administration, etc.
=20
I have one application group that, due to some security requirements,
cannot have any tape returned to scratch once it's been assigned.
=20
basically, the data in this environment is protected, so once it is
written to tape, those tapes are considered "protected".
=20
Right now, according to policy, once a disk is "protected", that's the
end of the line......it's tagged protect for ever, even if it's
overwritten with unprotected data.
=20
So, I need to create a volume pool for this application group, and I
would prefer for this volume group to be able to pull tapes from
scratch, IF necessary, but never return them to scratch.
=20
If I understand correctly, netbackup will only release tapes back to
scratch, if they were pulled from scratch to begin with, so if I ensure
that this pool is provisioned manually, it will never pull from scratch,
and therefore never return tapes to scratch......this could be a
possible solution, but I'm worried about the occasion where the pool was
underprovisioned and pulled a tape from scratch....once expired, it
would go back to scratch.
