1. Configure RMAN access to the Oracle Secure Backup SBT interface. If you are using Enterprise Manager Database Control, then this step involves registering the administrative server with Enterprise Manager.
This step is explained in “Configuring RMAN Access to the Oracle Secure Backup SBT Library”.
2. Create a preauthorized Oracle Secure Backup account for use by RMAN.
This step is explained in “Creating a Preauthorized Oracle Secure Backup Account”.
3. Optionally, create media families for datafiles and archived redo logs. By default RMAN uses the RMAN-DEFAULT media family.
This step is explained in “Creating Media Families for RMAN Backups”.
4. Optionally, configure database backup storage selectors or RMAN media management parameters. These settings give you more fine-grained control over backup behavior.
