Explanation

A cold backup site takes the longest recovery time. It is the most inexpensive type of backup site for an organization to operate. It does not include backed up copies of data and information from the original location of the organization, nor does it include hardware already set up. The lack of hardware contributes to the minimal startup costs of the cold site, but requires additional time following the disaster to have the operation running at a capacity close to that prior to the disaster. Answer option B is incorrect. A hot site is a duplicate of the original site of the organization, with full computer systems as well as near-complete backups of user data. Real time synchronization between the two sites may be used to completely mirror the data environment of the original site using wide area network links and specialized software. Ideally, a hot site will be up and running within a matter of hours or even less. Answer option D is incorrect. Although a mobile backup site provides rapid recovery, it does not provide full recovery in time. Hence, a hot site takes the shortest recovery time. Answer option C is incorrect. A warm site is, quite logically, a compromise between hot and cold. These sites will have hardware and connectivity already established, though on a smaller scale than the original production site or even a hot site. Warm sites will have backups on hand, but they may not be complete and may be between several days and a week old. An example would be backup tapes sent to the warm site by courier.
