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 interrupt read/write operations on your disk. We recommend that you set the creation time of automatic snapshots during off-peak business hours to avoid interruptions to your business services.
  • Automatic snapshot policies cannot be applied to unused basic cloud disks.
  • 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 using either of the following menus:

  • From the Cloud Disks menu. This method is suitable for applying an automatic snapshot policy to a specific disk.
  • From the Snapshots and Images menu. This method is suitable for applying a unified automatic snapshot policy to multiple disks.

From the Cloud Disks menu

To apply an automatic snapshot policy through the Cloud Disks menu, follow these steps:

  1. Log on to the ECS console.
  2. Select the target region.
  3. In the left-side navigation pane, click Disks.
  4. Select the disk for which you want to execute the policy and click Create Automatic Snapshot Policy.
  5. Enable the automatic snapshot function and select the desired snapshot policy.
  6. Click OK.

From the Snapshots and Images menu

To apply or disable an automatic snapshot policy, follow these steps:

  1. Log on to the ECS console.
  2. Select the target region. 
  3. In the left-side navigation pane, select Snapshots and Images > Automatic Snapshot Policies. 
  4. Select the automatic snapshot policy that you want to apply and click Apply Policy.
  5. To enable an automatic snapshot policy, select Disks without Policy Applied to view the disks. Find the disk for which you want to enable the policy, and then click Apply Policy after it. Alternatively, if you select multiple disks, click Apply Policy at the lower-left corner.

  6. To disable the automatic snapshot policy, select the Disks with Policy Applied tab to view the disks, select the disk for which you want to disable the policy, and then click Disable Policy at the right side. Note that if you select multiple disks, you need to click Disable Policy at the lower-left corner to disable the automatic snapshot policy for all selected disks.
