My sys admin reports that he can buy a lot of disk for the cost of the agent. We back up to disk and then move it to tape. We normally keep the last couple of level 0 backups on disk.

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
