Explain how to integrate RMAN with third-party Media Managers
Recovery Manager is the single tool for guaranteed, efficient, manageable Oracle
database backup and recovery. RMAN integrates with leading 3rd party backup
vendors for backup to tape, via the System Backup to Tape API. These backup
vendors have implemented interfaces to their products using the API, allowing
RMAN to drive backups to and restores from tape.
To store backups on tape, RMAN requires media manager software, a third party
software program that writes, reads, and manages sequential media such as tapes
to backup and recovery data. The core of the RMAN and media manager software
integration is the media management library, supplied by the backup vendor.
This library contains an implementation of the SBT API functions, and is linked
in with the Oracle server binary. Oracle calls these SBT functions to back up
and restore data files to and from media controlled by the media manager. When
performing backups or restores, the RMAN client connects to the target instance
and directs the instance to talk to the media manager. No direct communication
occurs between the RMAN client and the media manager; all communication occurs
on the target instance.
