Overriding an RMAN backup set/piece
I do take cold backups of my database (96G) using RMAN (to disk). My configuration parameter for disk storage is as follows:
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT $ORACLE_BASE/backup/db_name/%U';
This configuration creates a backup set with 3 pieces. Now, i need to set the configuration such that every time a backup is taken, it should override the present set/pieces & replace them with a new set/pieces, such that the old set/pieces would be automatically deleted.
Is there the possibility of doing this?
