Which metric must be updated if the maximum allowable data loss is set to 30 minutes during a catastrophic event?

The metric that must be updated when the maximum allowable data loss is established is the Recovery Point Objective (RPO). In this context, RPO specifies the maximum duration of data that can be lost as a result of a catastrophic event. If the RPO is set to 30 minutes, it means that, in the event of a disaster, up to 30 minutes' worth of data can be lost before recovery actions are deemed unacceptable. This metric is crucial for organizations to establish appropriate backup and data replication strategies that align with their data loss tolerance.

Updating the RPO ensures that the organization implements the necessary measures to minimize data loss to the defined threshold, such as more frequent backups or real-time data replication solutions. By continually adhering to this metric, the organization can mitigate potential impacts from data loss and maintain operational integrity.
