Depending on your server setup there will be a fight for tapes. Turning
collocation ON for your onsite pools would greatly increase the time to
create backup sets. I have 4 backup sets running every 2nd day at once
(I have 10 drives which leaves 2 drive available to do restores.) I have
also noticed that you are unable to perform storage pool backups during
the creation of backup sets (it keeps canceling the process).

PS - each backup set will use its own tape(s), I have a PRM (and others
do as well) to correct this problem.

Subject: How many concurrent backupsets?


After one weekend of selective full backups increased the size of the
database
by 20% ,
I have managed to talk management round to replacing them with
backupsets.
So all I have to do now is fit them into the available window.
So the question is
Has anyone noticed any constraints on the number of generate backup sets
that
can be run concurrently, before they start impacting on each other?
Is availability of tape drives going to be the only real constraint?
Has anyone wriiten backupsets to file devices to overcome drive
shortages?
Any problems with this?
Thanks
