In Huawei's distributed storage, the block service asynchronous remote replication architecture is based on the block service cluster to build an asynchronous replication relationship. Based on differential data, the data of the master and slave volumes are periodically synchronized. After the data synchronization of the last synchronization cycle is completed, the At the beginning of the current synchronization cycle, all data generated on the master volume will be written to the slave volume during this synchronization.
