What is the definition of Recovery Point Objective (RPO)?

Recovery Point Objective (RPO) is defined as the maximum allowable period in which data might be lost due to a disruption. It specifies the point in time to which data must be restored after a failure or outage, indicating an organization's tolerance for data loss. In practical terms, establishing an RPO helps businesses determine how frequently they need to back up their data to minimize the risk of potential losses. Hence, option C accurately captures this concept.

Understanding RPO is crucial for business continuity planning and developing effective disaster recovery strategies because it directly influences how data is managed and protected. If an organization sets an RPO of one hour, it means backups must occur at least once an hour to ensure that the most recent data can be restored, thus minimizing potential operational impact.

While the other options relate to aspects of IT management and business continuity, they do not specifically address the concept of data loss regarding its recovery objectives. For instance, maximum acceptable downtime refers to the Recovery Time Objective (RTO), while the durability of hardware touches on resilience rather than recovery points. The time required for system backups relates to operational processes but does not define RPO directly.
