Recovery Time / Recovery Point Objective
RTO is the maximum acceptable restoration delay; RPO is the maximum acceptable amount of recent data that can be lost.
Field note
RTO is the longest acceptable delay before a service is restored. RPO is the maximum acceptable amount of recent data loss, expressed as time before the disruption.
Recovery Time Objective and Recovery Point Objective grew out of business-continuity and disaster-recovery planning as two separate questions: how quickly must we return, and how far back may our data fall?
The objectives determine backup frequency, replication design, standby capacity and the cost of a recovery architecture.
Saying “we have backups” is incomplete unless the organisation knows whether restoration speed and data loss meet business needs.
In a sentence“Payroll has a four-hour RTO and a fifteen-minute RPO, so a nightly backup is not enough.”
