Cold/Warm/Hot Disaster Recovery Sitenoun* Hot site. It contains fully redundant hardware and software, with telecommunications, telephone and utility connectivity to continue all primary site operations. Failover occurs within minutes or hours, following a disaster. Daily data synchronization usually occurs between the primary and hot site, resulting in minimum or no data loss. Offsite data backup tapes might be obtained and delivered to the hot site to help restore operations. Backup tapes should be regularly tested to detect data corruption, malicious code and environmental damage. A hot site is the most expensive option. * Warm site. It contains partially redundant hardware and software, with telecommunications, telephone and utility connectivity to continue some, but not all primary site operations. Failover occurs within hours or days, following a disaster. Daily or weekly data synchronization usually occurs between the primary and warm site, resulting in minimum data loss. Offsite data backup tapes must be obtained and delivered to the warm site to restore operations. A warm site is the second most expensive option. * Cold site. Hardware is ordered, shipped and installed, and software is loaded. Basic telecommunications, telephone and utility connectivity might need turning on to continue some, but not all primary site operations. Relocation occurs within weeks or longer, depending on hardware arrival time, following a disaster. No data synchronization occurs between the primary and cold site, and could result in significant data loss. Offsite data backup tapes must be obtained and delivered to the cold site to restore operations. A cold site is the least expensive option.PhysicalRestrictedMay 9, 2026
