Disaster Recovery

Disaster Recovery is a situation where a set of running systems must be replaced by another set of running systems due to failure, damage, loss of connectivity, or other traumatic event. Disaster Recovery is a large-scale event and is not intended to replace fault tolerance where the failure of individual components can be recovered or otherwise accommodated without stopping a running system.

In a disaster recovery scenario, running systems are not expected to seamlessly or automatically failover to back up or alternative systems. Recovering from a disaster scenario implies a substantial and potentially large-scale system stoppage and a restart of an entirely new instance of the previously running system. It is not intended for short-term outages such as normal maintenance operations.

Note: The replacement systems activated during disaster recovery are designed to remain in operation for days, weeks, or even months depending on the severity of the disaster.
