What I would do is simply this:

Keep the backups and archives separate, and consider this:

Set-up a policy for each server that requires different rules. Keep point in
time backups for as long as is practical on each management class. You can
even separate the management classes into different storage pools to help
keep things straight. A low retention pool could be on disk even.

Then, choose the client nodes that have a requirement for archive. Assess
archives carefully so as to cut costs if possible. Then, you can extract a
'snapshot of data' from existing backup pools using create backup sets, and
catalogue them using a 3rd party product called Code Relief. I use this
method and run the archives on Saturday. It gives me the latest data for
that week, and I end up with a 52 week x 7 year archive. You could easily
make this happen daily, but the advantage is that I don't tax the
SAN/LAN/WAN for archives, the archives can be restored without the server
(LAN-less) and Code Relief is ALOT less than DRM (DRM doesn't catalogue
backup sets, and code relief does), and performs all the same disaster
recovery conventions. The down-side is that code relief only runs on Windows
(ack!) but it can work with an AIX server via ODBC.

Dunno if that helps, but anything is better than losing the incremental
forever paradigm (imho).

Good Luck!

Kevin.
