The only thing I can think of that would cause such behaviour is if for some reason you were actually running a cumulative incremental backup. From the script you've shown, that doesn't appear to be the case, but could you check the incremental_level of the rc_backup_set view in your recovery catalog and verify? ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Terry Sutton I'm having some issues with a client's RMAN backup. They're on Oracle 18.104.22.168, Solaris 8. It's a weekly full backup, and they're backing up ~1.5TB to disk, and the longer the instance is up, the longer the backup takes.
