Disaster recovery and failover are related, but they have some important differences. Disaster recovery refers to the process of restoring your critical systems and data after a significant disruption has occurred. This may include natural disasters, cyberattacks, hardware failures, power outages, and human errors. Disaster recovery is specifically designed to minimize the impact on your business by quickly restoring critical systems and data to normal operations. Failover, on the other hand, is a specific technique used to minimize the downtime of your systems in the event of failure. Failover typically involves the use of redundant systems that take over the workload of the failed system. For example, in a database environment, failover may involve the use of a secondary database server that takes over the workload of the primary database if a failure occurs.
