Disaster recovery is the process of responding to an interruption in the services your organization uses to operate. Disaster recovery usually is focused on information, network, and telecommunication services, often at an alternative site and using one or more data-recovery methods.

Disaster recovery is part of a larger topic called business recovery, which is restoring the actual capability for employees to perform their jobs. Business recovery includes logistic related items, such as telephones, office space, living arrangements for employees, and other logistical items. Business recovery itself is part of a larger topic called business continuity planning, which includes plans to manage the crisis to your organization, help resume normal business operations, and other inventions.

A resilient organization will use business continuity planning to help ensure that it can survive a disaster and resume operations at an acceptable level.
