Our backup goes to SAN, then get moved to DAD domain.
DAD domain replicate the backup to the other site DAD domain.
There might be off-site tapes for Month-end or year end.

I guess, in ways, it is backing up to SAN.

I learned how to setup/backup/restore using RMAN to disk locally on the target host. Now am trying to get some insight on RMAN/TDPO/TSM/SAN.

Just wonder if you or anyone there have worked with RMAN/TSM?
Any reporting/backup scripts might be helpful to me too.

Again, sorry for batting around the bush. Thought by now, I should be asking very pointed question.
