Recovery Time Objective (RTO) and Recovery Point Objective (RPO)
The RTO and RPO are important to designing a disaster recovery strategy. Hence, these two are extremely important aspects to understand from the exam perspective.
RTO
The RTO is a measure of the organization’s tolerance to system downtime. In other words, the RTO is the extent of the acceptable system downtime. For example, an RTO of two hours indicates that an organization will not be overly impacted if its system is down for up to two hours.
RPO
The RPO is a measure of the organization’s tolerance to data loss. In other words, the RPO is the extent of acceptable data loss. For example, an RPO of two hours indicates that an organization will not be overly impacted if it loses data for up to two hours.
The following figure further explains each of them:
