Disaster recovery relies on an off-site data center located in a separate geographic location to keep essential systems available when the primary data center experiences a disaster. This separation protects against a single event taking down both sites and provides a place where network servers and services can be brought online to restore operations. Depending on the DR setup, the time to switch over can vary—from facilities that are ready to go immediately to those that require a bit of activation or setup. The purpose is clear: ensure continuity by having a geographically separate facility capable of taking over when the main site is unavailable.
