The recovery point objective (RPO) deals with the backup frequency and the recovery time objective (RTO) with the recovery timeline. During a system outage, RPO and RTO can determine the impact of the downtime on business operations.
RPO is a measure of how frequently you take backups and indicates the amount of data that will be lost or needed to be reentered after an outage. RTO, on the other hand, is the amount of downtime a business can afford. It determines how long it might take for a system to recover after a business disruption.
