When the production system data is lost, it can be completely restored through the snapshot, which is an important data disaster recovery method. By making a fully usable copy of the designated cloud hard disk, the backup is made independent of the life cycle of the cloud hard disk. The snapshot includes the data of the hard disk at the point in time when the copy starts, and does not occupy the user's storage space. The user-created snapshot is stored in the object storage in a redundant manner, thereby further ensuring the reliability of the backup. Incremental backup of snapshots means that only the changed data is saved, which will shorten the time required to create a snapshot as much as possible and can save storage costs.
