Snapshot: Indicates the consistency data copy of the source data at a certain point in time. After a snapshot is generated, it can be read by the host or used as a data backup at a specific time point. The snapshot has only the source LUN and the snapshot LUN is automatically generated.
Clone: A snapshot technology is a full copy of the source data at a certain time point. It is a backup mode that can be incrementally synchronized. The clone has primary and secondary LUNs, and the clone must be the same on the unified storage.
