Detailed explanation-1: -Three forms of failover exist: automatic failover (without data loss), planned manual failover (without data loss), and forced manual failover (with possible data loss), typically called forced failover.
Detailed explanation-2: -Failover is switching to a redundant or standby computer server, system, hardware component or network upon the failure or abnormal termination of the previously active application, server, system, hardware component, or network in a computer network.
Detailed explanation-3: -The failover operation is the process of switching production to a backup facility (normally your recovery site). A failback operation is the process of returning production to its original location after a disaster or a scheduled maintenance period.
Detailed explanation-4: -Server failover is the practice of having a backup server (or servers) prepared to automatically take over if the primary server goes offline. Server failover works like a backup generator. When the power goes out in a building or home, a backup generator temporarily restores electricity.
