Slow down and and think this thru a little bit.  To make copypool tapes as
efficiently as possible you should be backing up the disk storagepool
frequently.  I do it 4 times a day.  Since backup storagepool is an
incremental process it only takes the new files which are all active
versions.

Regarding enhancing move data, I know IBM already has a user
requirement for it because I submitted one at a GUIDE conference more than 3
years ago.  Unfortunately it was returned as a suggestion. Perhaps someone
at IBM could look up the number so others
can concur on it.  This is still the best procedure isn't it?
