A target for the time allowed from the occurrence of a failure or disaster until business operations or the system resume. The shorter the RTO, the more equipment and cost are needed, such as standby systems and backups ready for immediate use.
Japanese name: RTO(目標復旧時間)
RTO (recovery time objective) appears in 3 practice questions across 2 topics, including System Architecture and Reliability, IT Service Management and Systems Audit.
Answer: B. Backups are taken every 3 hours, and recovery takes 1.5 hours when a failure occurs
If a failure occurs just before the next backup, data for the whole backup interval is lost, so meeting the RPO requires a backup interval no longer than the RPO. Also, the recovery time must be no longer than the RTO. With backups every 3 hours and recovery in 1.5 hours, at most 3 hours of data is lost (4 hours or less) and recovery takes 1.5 hours (2 hours or less), so both are met. The 1-hour scheme fails the RTO, and the 6-hour scheme fails the RPO.
Also, the recovery time must be no longer than the RTO.
For a system, the RPO (recovery point objective) is set at …First, the impact on the business is analyzed (business impact analysis) to determine the critical activities and their acceptable downtime, and targets such as the recovery time objective (RTO) and recovery point objective (RPO) are set for the systems that support them.
