Is RPO expressed in hours?

The statement is: "RPO is expressed in hours."

• RPO (Recovery Point Objective) is a metric used in business continuity and disaster recovery planning. It defines the maximum acceptable amount of data loss measured in time.
• RPO specifies the point in time to which data must be recovered. For example, an RPO of 1 hour means that in the event of a disruption, the system should be recoverable to a state no older than 1 hour before the disruption occurred, meaning a maximum of 1 hour of data loss is acceptable.
• While RPO can be expressed in hours, it is not exclusively expressed in hours. Depending on the criticality of the data and the business requirements, RPO can be expressed in various units of time, such as seconds, minutes, hours, or even days. For highly critical systems, an RPO might be in minutes or even seconds.

Therefore, stating that RPO is expressed in hours (implying it is the only or universal unit) is incorrect.

The correct answer is $\text{False}$.
