Database Backups

You can perform an online database backup using the following method:

To perform a database back up, the Agent for Oracle generates an RMAN script based on the options you select in the agent user interface (that is, the Backup Manager).
The agent then calls RMAN to execute this script.
When RMAN starts, it generates other agent jobs to perform the actual backup.
These agent jobs receive data blocks from the RMAN and then sends them to Arcserve Backup for backup to the media drive.

Note: The agent and Arcserve Backup can back up a complete database or objects within the database.

You can also perform an offline backup with the agent using the following procedure:

To perform offline database backups, the agent puts the database in a quiescent state before beginning the backup process.
This quiescent state allows the database to remain accessible to RMAN throughout the backup process, but does not let anyone access the database or run transactions.
