Hi,
I have a scenario where I want to back up the same database to two different media. In particular I want to back up to tape with a retention period of, say 30 days, but on occasion I'd like the same backup to go to disk. However disk is smaller so I'd like the retention period to be just a couple of days.
I have read through RMAN Recipes for Oracle Database but couldn't see how this can be done. So is it possible?
Also there are times when the tape media won't be available and so I'd like to take the backup on disk and copy it to tape. I know you can do a backup ... backupset but I don't know where this implies the disk backup set needs to hang around? TIA.
Wombat.

>> what is stopping rman from deleting a later backup from veritas
In this case RMAN does not talk to tape library directly, even cannot "see" the tapes.
RMAN will always write to disk. No MML involved and RMAN cannot see the tape. RMAN retention policies will now apply only for Disk.
Veritas will always pick the backupsets created by RMAN and write to tape. Retention policies are set in Veritas for tapes.
Alternatively,
Look into option.
