Develop a Backup Strategy

To have a backup strategy, you should:

Perform a full online backup of your Oracle databases.
Perform a cold database backup on a regular basis by shutting down the database and performing a file system backup of the Oracle environment.
Back up database objects to update the full database backup. Heavily used tablespaces should be backed up frequently to reduce database recovery time.
Back up the database control files each time you make a structural change to the database.
Mirror Oracle online redo logs. The agent does not perform this procedure. For more information about mirroring online redo logs, see the Oracle Documentation.

For more information about Oracle backup and recovery procedures, see the Oracle documentation.
