I can't tell from my experience, but have heard from some quite knowledgeable guys at IOUG, that backing up files to type through RMAN could have some issues (e.g. if the tape drive has a problem in a middle of the process). If you have enough space on disk, I would suggest to go to disk first and than from the disk to backup to tape for longer data keeping if necessary.

Hi!

We are about to redesign our backup environment. All Oracle Backups (8i, 9i) are done with RMAN. Now we are unsure whether to have RMAN backup to tape or to a specific area on our SAN.

Backing up to the SAN (i.e. disk) is an option, since you don't need Veritas NetBackup Oracle Agents (which are horribly expensive). We would have RMAN write the backups to disk and then move those backups to tape. The disk will be about the size to hold two weeks worth of RMAN backups.

Would this make sense? Or is it preferable to backup to tape, no matter what?

This is 8i & 9i on Sun Solaris.

Thanks,
Helmut
