Disaster Recovery involves a set of policies, tools and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster. Disaster recovery focuses on the IT or technology systems supporting critical business functions, [1] as opposed to business continuity , which involves keeping all essential aspects of a business functioning despite significant disruptive events. Disaster recovery can therefore be considered a subset of business continuity. It also incorporates those elements of IT infrastructure and services which relate to communications such as voice telephony and data communications. Planning includes arranging for backup sites, be they hot, warm, cold, or standby sites, with hardware as needed for continuity.
