Failback is the process of returning system operations and information processing to their previous state after a failover. A failover event can happen if a system component, such as a data centre or server, malfunctions or experiences an outage.

Failback procedures help maintain business operations and process continuity, restoring secure system operations and efficiency after failures. The failback types the organisation employs depend on the specific priorities and requirements it has set up in its cybersecurity or disaster recovery measures.
