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

Helmut,

What amount of $$ is 'horribly expensive"?

The Oracle Agent for Veritas is about $2500 per server if I recall correctly. They don't give it away, but it isn't *that* much.

Someone else said that there SA could buy a lot of disk for the price of the agent. In a SAN, $2500 will generally buy you about 2.5 disks.

Personally, I dislike backing up to disk. That creates a logical disconnect between RMAN and the Veritas backup catalog.

ie. You can't then just tell RMAN to restore your database to anytime other than what is on the backup disks. If the backup files are lost/damaged, you must be certain to restore all of the files needed Oracle files from tape to disk, then do your recovery.
