Which of the following disaster recovery metrics is used to describe the amount of data that is lost since the last backup?
Suggested Answer: C Vote an answer
* Definition of RPO:
* Recovery Point Objective (RPO)is a disaster recovery metric that describes the maximum acceptable amount of data loss measured in time. It indicates the point in time to which data must
* be recovered to resume normal operations after a disaster.
* For example, if the RPO is set to 24 hours, then the business could tolerate losing up to 24 hours' worth of data in the event of a disruption.
* Why RPO is Important:
* RPO is critical for determining backup frequency and helps businesses decide how often they need to back up their data. A lower RPO means more frequent backups and less potential data loss.
* Comparison with Other Metrics:
* MTTR (Mean Time to Repair):Refers to the average time required to repair a system or component and return it to normal operation.
* RTO (Recovery Time Objective):The maximum acceptable length of time that a computer, system, network, or application can be down after a failure or disaster occurs.
* MTBF (Mean Time Between Failures):The predicted elapsed time between inherent failures of a system during operation.
* How RPO is Used in Disaster Recovery:
* Organizations establish RPOs to ensure that they can recover data within a timeframe that is acceptable to business operations. This involves creating a backup plan that meets the RPO requirements.
