Each DRaaS offering you look at will define in their Service Level Agreement (SLA) what their promised RPO and RTO are. Recovery Point Objective (RPO) refers to the point in time in the past to which you will recover. Recovery Time Objective (RTO) refers to the point in time in the future at which you will be up and running again. Think of the above diagram as a timeline of events during which a disaster happens. The RPO will be the point to which you will have all data up to that point recovered. The gap between the disaster and the RPO will likely be lost as a result of the disaster. On the timeline, RTO is the point in the future at which you will be back up and running full speed ahead.
