Recovery Point Objective (RPO) and Recovery Time Objective (RTO)

Two critical concepts to measure availability are those of Recovery Point Objective (RPO) and Recovery Time Objective (RTO). Fully understanding these two concepts will allow you to choose the best solution for your particular use case, budget, and business requirements.

The concepts of RPO and RTO, in addition to an analysis of the business impact, will provide the foundation to nail down an optimal recommendation for a business continuity plan. The strategy used should ensure that normal business operations resume within an acceptable time frame that meets or exceeds the RPO and RTO for the agreed-upon Service-Level Agreement (SLA).

It would appear that these two concepts are the same or at least quite similar. In the next section, we will delve into the two concepts to fully understand how they differ.
