Which statement best describes RPO in disaster recovery?

Which statement best describes RPO in disaster recovery?

• A. The maximum downtime allowed before full service restoration
• B. The maximum allowable amount of data loss measured in time, such as minutes
• C. The total size of backups required
• D. The expected uptime percentage

Answer: (B)

RPO is about how much data you can afford to lose, expressed as a time window. It defines the maximum tolerable data loss in case of a disaster. If your RPO is 15 minutes, you must be able to restore data that goes up to 15 minutes before the disruption, which drives how often you back up or synchronize data to a DR site. This is different from RTO, which is about how quickly you must restore service after a disruption. The statement describing data loss in time best fits this concept. The other ideas refer to downtime duration (RTO), backup size, or uptime targets, which aren’t the same as RPO.
