RTO vs RPO: What They Mean and How to Set Them Honestly
Recovery time objective (RTO) is how long a system can be down before the impact becomes unacceptable. Recovery point objective (RPO) is how much data the business can afford to lose, measured as a window of time before the incident. RTO looks forward from the moment things break. RPO looks backward from it. That distinction takes a paragraph to explain and years to get right, because the difficult part was never the definition.
