Something we did that helped some -

We backed up the DASD pool first, and then ran only backups of the DASD pool
for a couple of weeks.  Then we started the backup of the tape pool as Ron
suggests.  The DASD pool backups are faster, obviously because there are only
output tape mounts; and by running the two weeks of DASD only backups first,
we eventually cut down on the amount of tape data that needed to be backed
up.

Fred,
You are on the right track.  After the first big copy, the nightly
copies will be easy.  I fire off a backup copypool about 4 am each
morning to get the copy pools up to date from the night's backups.  Bear
in mind that for the first big copy of 300GB you can start and stop the
backup copypool many times, and, if you are limited on tape drives, you
will have to.  You will pay a time penalty, though, each time ADSM has
to figure out where he left off (on the order of about 30 min to an
hour).
Good luck, its fun to watch it grow. Ya I know, I'm sick and twisted.
Not as bad as that Dwight Cook, though...
