What is Disaster Recovery Site?

Disaster Recovery Site is a location used by an organization for restoring its IT infrastructure and business critical operations where a primary production center is affected by a natural or man-made disaster.

Disaster Recovery Site are often built in a remote location to ensure that the disaster which has affected the main site will not affect the secondary site as well.

Types of Disaster Recovery Site

Hot site: A hot site is a mirror copy of the primary production centre. It is equipped with all the necessary hardware, software network connectivity, which allows to perform real-time backup or replication of the critical data.

Cold site: A cold site is a backup facility with little, or no hardware equipment installed. It is essentially an office space with basic utilities such as power, air conditioning, communication, etc. Due to the fact, that the cold site doesn’t have any preinstalled equipment, it takes a lot of time to properly set it up to fully resume business operations.

Warm Site: A warm site is a backup facility that has the network connectivity and the necessary hardware equipment already pre-installed. However, a warm site cannot perform on the same level as the production center because they are not equipped in the same way. Data synchronization between the primary and secondary sites is performed daily or weekly, which can result in data loss. A warm site is perfect for organizations with operate with less critical data and can tolerate a short-term loss of data.
