In Huawei distributed storage, the block service asynchronous remote architecture builds an asynchronous relationship based on the block service cluster. 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, until the start of the current synchronization cycle, all data generated on the master volume will be written to the slave volume during this synchronization.
