Backup optimization applies only to the following commands: BACKUP DATABASE BACKUP ARCHIVELOG with ALL or LIKE options BACKUP BACKUPSET ALL By default, backup optimization is configured to OFF. To enable backup optimization, run the following command: ONFIGURE BACKUP OPTIMIZATION ON; To disable backup optimization, run the following command: ONFIGURE BACKUP OPTIMIZATION OFF; To clear the current backup optimization setting, that is, return backup optimization to its default etting, i.e .
