In actual service scenarios, the HyperMetro feature of Huawei OceanStor Pacific series supports incremental synchronization.

The HyperMetro feature in Huawei OceanStor Pacific series provides active-active storage with high availability. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* states: “HyperMetro supports incremental synchronization. In the event of a site failure, the site that wins arbitration (via quorum server or static priority) continues services in single-write mode. After the faulty site recovers, HyperMetro resumes dual-write mode and synchronizes incremental data generated during the fault to the recovered site, ensuring data consistency.” This process ensures minimal data loss and seamless recovery, making the statement true. The material emphasizes that incremental synchronization reduces the bandwidth and time required compared to full synchronization.
