Just delete the backups using the OS delete. The backup will stay in the catalog (or controlfile) until the window is passed. Do not delete it from the catalog or using rman. HTH, Ruth p.s, We used to do just exactly this. Now we just do a level 0 every nite. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of JayMiller@xxxxxxxxxxxxxxxx Sent: Tuesday, March 29, 2005 11:44 AM To: oracle-l@xxxxxxxxxxxxx Subject: Simple RMAN question Okay, I know there must be a way to do this but none of us here are very experienced at RMAN and I haven't found it in my documentation searches. We want to do a level 0 backup once a week and incremental backups daily on one of our databases. We backup to disk and then copy the backups to tape. In order to conserve space we'd like to delete the level 0 backup but when we do that the validation of the incremental backup fails. Is there any way around this?
