failover

Invoking a secondary system to take over when the primary system fails. Up-to-date copies of all required data and applications are maintained on the secondary system in order to respond immediately if the primary system becomes unusable. Also called "fallover." See replication.

(reliability)failover - Automatically switching to a redundant or standby server, system, or network upon the failure or abnormal termination of the currently-active server, system, or network (a "hot standby" or "warm standby"). Failover happens without human intervention. This feature is usually built-in to expensive systems which must be available continuously.
