You will have to do a few things to get this done:

1.  Change your backup schedules to start backing up with a 3 month
retention
2.  Change Vault to extend the off-site copy for the 1 year retention you
need
        for those classes
3.  Go through the catalog database and expire all on-site copies of the
data
        that are over 3 months old

#3 is a time consuming job.  But, it can be done (if I can do it, anyone
can).  Of course, if you don't mind allowing the current copies to expire on
their own, you can skip #3 altogether.

Hi,

We want to expire our media in the robots after 3 months. Right now it is
set at
a year. We use BP Vault and offsite for a year all Full data (captured
monthly).

Is there any reason to not set the local expire (for all incr, cincr and
full)
media for 3 months, instead of a year as it is currently set.

Basically, the systems we are backing up are not trivial, so we are finding
Fulls are very big, and take alot of tapes, and we need to be able to
recycle
something in this picture in order to survive.

Any suggestions or thoughts?


Thanks!

Chris
