robopet3The most basic form of Disaster Recovery is called Cold, because there are no active (“hot”) services running at a different location (Disaster Recovery site) and all services are provided from a single location or data center.
In the other extreme, there is Hot Disaster Recovery, which provides no down-time (zero RTO) and updated data everywhere (zero RPO).
In between Cold and Hot Disaster Recovery there is a continuum of intermediate RTO/RPO requirements called Warm Disaster Recovery. These setups can be closer to either extreme, Cold or Hot, according to Business requirements and available budget.
