We are about to start backing up our enterprise databases.
They are comprised of about 15 Oracle instances ranging from 7GB to 25GB.
About a third are being backed up nightly and the others are either 1 or 2 times
weekly.

On the server side, we will set up a seperate stgpool hierarchy as they there
will be expectations for QOS etc. (I will seperate them out onto a 2nd server
later this year)

There are no TDPs available (Dynix) so we have to use the command line client
to backup. The DBAs run the database in backup mode and cpio the files to
a staging area, then the TSM client will scoop them up.

They want a 30day retention period with one backup a month kept for a year 
(acheived
by a management class flag on dsmc)

Question:
Should we run incrementals or archive the files considering we have a date, as
opposed to frequency, retention requirement?
