RE: RMAN Backup to tape or disk (SAN) ???

It really depends on if you have the
(1) funding for disk and
(2) the size of your databases
(3) other types of high-availab. solutions in-place and
(4) SLA - i.e. business requirements all matter.
(5) reliability and speed of the tape subsystem and media management layer
itself    

Always, always, always practice non-destructive recoveries under various circumstances, and consider the least obtrusive restore required for any given scenario.

RMAN backups to disk are always faster than backups directly to tape. Disk has gotten cheaper so I would look at disk first. You can put the backups on tapes using the OS tape facilities after they are done.

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
