Disaster Recovery (DR) is the process an organization uses to recover access to their software, data, and/or hardware that are needed to resume the performance of normal, critical business functions after the event of either a natural disaster or a disaster caused by humans.
Disaster Recovery Plans are generally part of a larger, more extensive practice known as Business Continuity Planning. DR plans should be well practiced so that the key players are familiar with the specific actions they will need to take should a disaster occur. DR plans must also be adaptable and routinely updated, e.g. if new people, a new branch office, or new hardware or software are added to an organization they should promptly be incorporated into the organization’s disaster recovery plan. Companies must consider all these facets of their organization as well as update and practice their plan if they want to maximize their recovery after a disaster.
