With failover, two TeraStations are connected to the network for redundancy. If a problem occurs in the main TeraStation so that it can no longer be accessed, operation is automatically switched to the backup TeraStation.
Note: Use identical model and capacity TeraStations for the main TeraStation and backup TeraStation. If the capacity of the main TeraStation is larger than that of the backup TeraStation, an I33 replication error will occur.
