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, the data of the master and slave volumes are periodically synchronized. From the data synchronization of the last synchronization cycle completes to the current synchronization starts, all data generated on the master volume will be written to the slave volume during this synchronization.

In Huawei distributed storage, SCSI volumes with multiple mount points are called shared volumes, and iSCSI volumes are shared volumes. In order to support the backup capability of shared volumes, the block service also supports snapshots of shared volumes, and the snapshot process of shared volumes is the same as that of ordinary volumes.
