Because we are not using RMAN to back up the rac database, the views V$RMAN_* are empty.
Backup Operations
In this section, we??™ll run through some examples to back up the target database in a variety of
ways: We??™ll perform two kinds of full backups, create image copies of selected database files,
investigate how incremental backups work, and delve further into backup compression,
incremental backup optimization, and the flash recovery area.
We??™ll continue to use our data warehouse database, dw, as the target database, with the
database rac as the RMAN repository.

Full Database Backups
In our first example of a full database backup, we??™ll use backupsets to copy all database files,
including the SPFILE, to the flash recovery area:
RMAN> backup as backupset database spfile;
