I think our problem is that although I agree that what you say works, we
don't keep an onsite copy of the backup. So while if a restore is
initiated from RMAN, NetBackup will work out where the primary backup
image is, in our case that will just cause an operator request to get the
tape and load it, as it is offsite. Current practice by the DBAs has been
to get the picking list from RMAN, have the tapes recalled and loaded, and
only start the restore when they know the tapes are in the library.
So I guess what they are after is being able to use RMAN to generate the
picking list. It sounds as if running the RMAN 'crosscheck' after the
duplication (or when preparing for a restore) may fixup the RMAN catalog.
However I think I'm going to have the test that.
Of course I'd rather we had an onsite copy, but that is not yet on offer.
