There are certain environments
here that require only a 2 week retention, no matter what. In this environment
we run full backups everyday and when the data set is in the 80 TB range, well
that just more then I need to deal with. We have been running this way for
years with no major issues. Leave it up to Oracle to take 2 weeks 4 hours to
try and fix RAC.

How about setting a longer retention period and _expiring_
backups if the conditions you’re looking for have happened?
As long as I’m at it, I think a two week retention period is
crazy. You should always have AT LEAST three full cycles. (IOW, if
you’re doing a full backup every week, I think you should have at least a
three week retention period.) My preference would be at least a month for
database backups and 90 days for filesystem backups.
As to what other products do…
NetWorker won’t expire a full backup if there are incremental
backups based on it. In your case, they would/could have expired too and
the oldest full might have expired.
TSM doesn’t expiration like this. It keeps versions,
and does not think the way these products think unless you force it to. I
therefore think that TSM wouldn’t have done what NetWorker did.
Did I mention that a two week retention period is too short? ;)

We had an issue where was server was down for over 2 weeks
and the last full backups expired. The retention for this environment is 2
weeks. After the tapes expired the App team decided they wanted to restore. Now
management wants Veritas to extend the retention period automatically if a full
is not successfully run. I do not know of any company that has this capability
so I am looking for ideas. I do not think it would be possible for a person to
manually track all the servers and their last full and then manually bpexpdate
the images. I have pushed back with the question of why was this server allowed
to be down for 2 weeks but nobody is answering.
