Disaster recovery process

;
Disaster recovery is the process, policies and procedures related to preparing for recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced disaster.

Disaster recovery planning is a subset of a larger process known as business continuity planning and should include planning for resumption of applications, data, hardware, communications (such as networking) and other IT infrastructure. A business continuity plan (BCP) includes planning for non-IT related aspects such as key personnel, facilities, crisis communication and reputation protection, and should refer to the disaster recovery plan (DRP) for IT related infrastructure recovery / continuity. This article focuses on disaster recovery planning as related to IT infrastructure.
The terrorist attacks of September 11, 2001 have taught many businesses one thing: prepare for the unexpected. Companies must take steps to make their businesses less dependent on a single office or data infrastructure. Consider implementing technologies that can quickly duplicate company data at a remote location. Gartner Research predicts that two out of five enterprises that experience a disaster the magnitude of the World Trade Center attack will go out of business within five years. Therefore, it is more important than ever to either build a redundant IT facility, or select an IT outsourcing service provider for disaster recovery.
