In Huawei distributed storage, the block service asynchronous remote replication architecture is based on the block service cluster to build an asynchronous replication relationship.

Based on the difference data, periodically synchronize the data of the master and slave volumes. After the data synchronization of the last synchronization cycle is completed, the current synchronization cycle starts.

Initially, all data generated on the primary volume will be written to the secondary volume during this synchronization.
