RMAN backup Optimization

Oracle Database Tips by Burleson Consulting

May 10, 2015

Question:  What is the RMAN backup optimization feature and how does it work?

Answer:  The RMAN backup optimization feature is controlled by these commands:

RMAN> configure backup optimization on;
RMAN> configure backup optimization off;


When you turn on backup optimization, all backup commands will skip backups of any file if it has not changed and if it has already been backed up to the allocated device type.  A file can be any dbf file, an archived redo log or an RMAN "backup set".  Here are some of the main features of the RMAN configure backup optimization on command:

  • In order to back up the flash recovery area itself using RMAN, you must set configure backup optimization to ON.
  • Setting backup optimization on stops the backups of Read Only Tablespaces (ROT), whenever a valid backup of the tablespace already exists in the RMAN catalog database.
  • If backup optimization is enabled, then RMAN skips backups of archived logs that have already been backed up to the allocated device.
