RE: compressing rman backups through pipes

Ruth - If you have space for individual RMAN backups, but not enough room for all RMAN backups, consider this. For simplicity, assume that you only have two production databases on your system.

• Backup database A using RMAN.
• Copy the backup to tape.
• Delete the disk copy of the RMAN backup.
• Backup database B using RMAN
• Copy the backup to tape.

This means that if you have to recover database A, then you'll have to delete backup B and read A's backup in from tape. That means the recovery time will be longer. But maybe not that much longer than if you were using a media manager and writing directly to tape.

        Actually, we are considering a schedule like this down the road. Buy a cheap NAS unit just to hold backups until they are copied to tape.

        Incremental backups, staggered days, etc. may make this arrangement more usable.

If I get it to work, which from everything I've heard so far won't happen, I will be happy to let everyone know. As of today, I had to compress some backup sets so I could backup the last production database. What a waste of time!
