What metric specifies how much data can be lost during a database failure or catastrophic event?

1. RSO

2. RPO

3. RTO

4. DBO

The correct answer is: RPO

The metric that specifies how much data can be lost during a database failure or catastrophic event is referred to as Recovery Point Objective (RPO). RPO indicates the maximum period in which data could be lost due to a failure. It essentially helps organizations define how much data loss is acceptable in terms of time. For instance, if the RPO is set to one hour, it implies that, in the event of a disaster, the organization can afford to lose data that was created within the last hour leading up to the incident. This concept is crucial for designing disaster recovery and backup strategies, ensuring that businesses can resume operations with minimal loss of data. The other options reflect different recovery metrics. Recovery Time Objective (RTO) pertains to the amount of time that can elapse before the operations are restored post-disruption. DBO generally refers to Database Owner, which is not relevant in this context. RSO is not a standard metric used in the context of data loss or recovery objectives, further differentiating it from RPO. Understanding these differences is key to establishing effective data protection strategies in cloud environments and other IT infrastructures.
