The recovery time objective (RTO) in a DR system refers to the time to which...

This statement is false because it confuses RTO (Recovery Time Objective) with RPO (Recovery Point Objective). In Huawei’s Disaster Recovery (DR) documentation, these two metrics are defined as follows:

RPO (Recovery Point Objective):Refers to the maximum amount of data loss an organization can tolerate, measured in time. It indicates the "point in time" to which data must be recovered (e.g., "we can only lose 1 hour of data").

RTO (Recovery Time Objective):Refers to the duration of time within which a business process must be restored after a disaster. It measures how long the system can be down before the business is significantly impacted (e.g., "the system must be back online within 4 hours").

The question describes the "point in time" (RPO) but labels it as RTO. In a high-availability solution likeHyperMetro, the RTO and RPO are both theoretically zero, meaning no data loss and no downtime.
