My experience has been just the opposite, my backup supposedly ran
successfully to veritas tape this morning, although the restore database
validate command failed, tape went bad from the time it finished backup
and couldnt read info back off for the validate. I've never had a
problem writing to disk w/RMAN.

Helmut, i'm always of the concept, if you have the disk by all means backup to disk first and then always backup those files to tape, sure it means potentially 2 stage process to do recovery if you have to get things back from tape first but since you have the disk and can keep copies on disk, its always faster to restore from 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
