A disaster recovery plan (DRP) primarily focuses on the dealing with the effects of a disaster and the prescribing of actions to be taken after the fact. In most cases, this encompasses several measures such as redundancy, evacuation plan, how fast and how long the system can be restored and service can be resumed.
The second key issue that a DRP focuses on is the possible impact and potential threats to the business continuity. Natural disasters such as earthquake, flood and fire or even disasters by human being such as war, terror attack are inevitable. Therefore, to develop a DRP also include a Business Impact Analysis. This analysis identifies key systems that need to be maintained, as well as the potential threats to the business continuity.
