RTO and RPO in plain language
Recovery Time Objective (RTO) answers: how long can this system be down before the business is seriously harmed? Recovery Point Objective (RPO) answers: how much recent work can we afford to lose?
An eight-hour RTO and a 24-hour RPO is a nightly backup restored to spare hardware. A fifteen-minute RTO and a fifteen-minute RPO is a very different architecture with local virtualization and continuous replication. The design follows the number the business chooses — and the cost follows the design.
