A warm site is a type of disaster recovery site that provides the necessary infrastructure for a business to continue operations after a disaster. It typically includes basic hardware such as servers, storage, and networking equipment, as well as power, cooling, and connectivity. The warm site is ready to be used in the event of a disaster, but the business must still provide the software and data needed to resume operations.
