The need for High Availability (HA) and Disaster Recovery (DR) To guarantee business continuity, it is necessary to use both high availability AND disaster recovery technologies. High availability, as defined, protects us from day-to-day events that can affect device availability, such as hardware failure, network failure, load-induced failure, or other failures of the application. 2013-06-28 · High availability covers hardware or system-related failures, whereas disaster recovery can be used in the event of a catastrophic failure due to environmental factors. Although some of the high-availability options may help us when designing our DR strategy, they are not the be-all and end-all solution. High Availability vs Disaster Recovery.
