Hi,
In our organisation, Backups are taken through Rman on tapes. I've 2 questions

1. I need to check whether backups are valid or not, how can I check.

2. Is it possible to restore the backup to different database with same structure and perform recovery?

Thank you,

The best way to test the validity of your backups is to restore to another node (Restore and Recovery of the Database on a New Host).

The first response is a very valid one; but, doesn't address your second question. If you are using 10g R2 you can do what you are requesting - it's called transportable tablespaces from RMAN. Obviously, you do not restore the entire backup to another instances, just user tablespaces.

hi
The main purpose of RMAN validation is to check for corrupt blocks and missing files. You can also use RMAN to determine whether backups can be restored.

RMAN> VALIDATE DATABASE;

RMAN> VALIDATE BACKUPSET 22;
