What is the process called that switches to a standby component when the primary fails to maintain service?

Explanation:
Failover is the process of switching to a standby component when the primary fails to maintain service. In high-availability setups, systems run with redundancy and health monitoring so that if the primary component becomes unavailable, traffic and services are automatically redirected to a standby component, keeping the system online with minimal disruption. Failover can be automatic or manual, depending on the design. Once the primary is healthy again, you may return operations to it through a failback, but that is the reverse action, not the switch itself. Backups provide data copies for restoration, not live service switching, and redundancy describes having spare components—the infrastructure that makes failover possible.
