Which of the following disaster recovery metrics is used to describe the amount of data that is lost since the last backup?
Which of the following disaster recovery metrics is used to describe the amount of data that is lost since the last backup?
The Recovery Point Objective (RPO) is the disaster recovery metric used to describe the maximum acceptable amount of data loss measured in time. It defines the point in time to which data must be restored in order to resume business operations after a disaster. Hence, it is directly related to the amount of data that is lost since the last backup.
- MTTR: Average time to fix a system after failure. - RTO: Max time allowed for system recovery after disaster. Selected - RPO: Max acceptable data loss time from last backup. - MTBF: Average time between system failures.
A. MTTR (Mean Time To Repair): This refers to the average time it takes to repair or recover a system or component after a failure. B. RTO (Recovery Time Objective): This is the maximum amount of time allowed to restore a system or service after a disaster or outage. C. RPO (Recovery Point Objective): This is the maximum amount of data that can be lost during a disaster or outage, measured in terms of time. D. MTBF (Mean Time Between Failures): This is the average time between failures of a system or component.
