The right half is labeled "Standby Location," and consists of a remote standby database icon on the left and a Recovery Appliance icon on the right. An arrow labeled "Fast Incremental" points right from the remote standby database to the Recovery Appliance. Below that, an arrow labeled "Redo" also points from the remote standby database to the Recovery Appliance.
