The Recovery Appliance backup module is an Oracle-supplied SBT library that functions as a media management library. RMAN uses the Recovery Appliance backup module to transfer backup data over the network to the Recovery Appliance. The backup module is referenced when allocating or configuring an RMAN SBT channel for backup or recovery operations to the Recovery Appliance. All backups to the Recovery Appliance, and all restores of complete backup sets, are performed by means of this backup module.
