Failback is a term used in computer architecture and refers to the process of switching back to the primary server, storage, or network infrastructure after a failure occurs. It is the opposite of failover, which involves the switchover to backup systems when the primary systems fail. Failback is an essential component of high-availability systems as it ensures that the primary systems can resume their duties after being repaired. It is a critical process in minimizing downtime and ensuring business continuity in the event of system failures.
