The contribution of recovery point objective (RPO) to disaster recovery is to define backup strategy because it determines the maximum amount of data loss that is acceptable to an organization after a disruption, and guides the frequency and type of backups needed to restore the data to a usable format1. Minimize outage periods is not a contribution of RPO, but rather a contribution of recovery time objective (RTO), which defines the maximum amount of time that is acceptable to restore normal operations after a disruption2
. Eliminate single points of failure is not a contribution of RPO, but rather a goal of high availability (HA), which ensures that systems or services are continuously operational and resilient3. Reduce mean time between failures (MTBF) is not a contribution of RPO, but rather a measure of reliability, which indicates the average time that a system or component operates without failure4.
