failover

(redirected from Failback)

failover

(reliability)
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.

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.
