An industry customer purchases an OceanStor Dorado 8000 storage system for service data deployment. To improve data reliability and security, engineers configure HyperDetect in the storage system for data protection. Which of the following statements is false about this feature?

A government customer purchases multiple Huawei flash storage systems to deploy remote replication services. During asynchronous remote replication of LUNs, engineers need to replicate data at time point X from the primary LUN to the secondary LUN based on data change logs (DCLs). After data synchronization is complete, snapshots of the primary and secondary LUNs are automatically deleted, in this way, storage space occupation is reduced.
