Protected database backups can be stored on Recovery Appliance using one of the following techniques:

• Protected databases send backups directly to a Recovery Appliance

  The protected database administrator authenticates and connects to a Recovery Appliance and then backs up the protected database to the Recovery Appliance. The Recovery Appliance backup module is used to send backups over the network to the Recovery Appliance. The incremental-forever backup strategy is used to back up protected databases to the Recovery Appliance. If required, you can configure real-time redo transport to transmit redo data directly to the Recovery Appliance.

  Before you send protected database backups to a Recovery Appliance, you must enroll the protected database with the Recovery Appliance and configure settings.

• Recovery Appliance automatically picks up protected database backups from a shared location

  Instead of directly interacting with a Recovery Appliance, the protected database writes backups to a configured shared storage location. The Recovery Appliance uses backup polling to periodically check the shared storage location and pick up new backups stored in this location.
