The decision about what kind of DR site an organization needs and its location requires careful planning and a balance of costs against any risks. There are two fundamental DR site options: internal and external. An organization sets up and maintains an internal site while an external site is owned and operated by an outside provider. Companies with large information requirements and aggressive recovery time objectives are more likely to use an internal DR site. The internal site is typically a second data center and allows a company to recover and resume operations following a disaster at the primary center.
