How Is a Snapshot Created for My Disk?

There are two types of snapshots: manual snapshots you create on-demand and automatic snapshots created by the system.

  • Manual snapshots: You may manually create snapshots to rapidly save the disk data at specific points of time. This feature is now in open beta testing and is free for trial use. For details about how to create snapshots, see Creating a Snapshot (OBT).
  • Automatic snapshots: During the creation of a cloud server backup, or a disk backup with the CBR service, the system automatically creates a snapshot and saves the latest snapshot for each disk. If a disk already has a backup, after another backup, the old snapshot will be deleted and the latest one will be retained. This snapshot is free of charge. You can view the snapshot details only but cannot perform any operations on it.
