Since it requires twice the disk space than actual data, mirroring is the less cost-efficient data redundancy strategy.<br \/>\nSource: SWANSON, Marianne, &#038; al., National Institute of Standards and Technology (NIST), NIST Special Publication 800-34, Contingency Planning Guide for Information Technology Systems, December 2001 (page 45).<\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following statements pertaining to disk mirroring is incorrect?
