You can apply an automatic snapshot policy to disks according to your business needs.

Automatic snapshots are named in the format of auto_yyyymmdd_1, for example, auto_20140418_1.

Note
  • Creating snapshots may disturb read and write operations on your disk. We recommend that you set the creation time of automatic snapshots to periods when service load is low to reduce effects on your service.
  • Automatic snapshot policies cannot be applied to basic cloud disks when they are not in use.
  • Snapshots that are manually created do not conflict with automatic snapshots. However, if an automatic snapshot is being created on a disk, you must wait for it to finish before manually creating a snapshot.

You can apply an automatic snapshot policy to a disk through either of the following:

  • Cloud Disks menu: For applying an automatic snapshot policy to a specific disk.
  • Snapshots & Images menu: For applying a unified automatic snapshot policy to several or all disks.
