You can create instance snapshots to save the system state from a certain point in time for data backup or to create images.

Note
  • Creation of the first snapshot will take relatively longer than subsequent snapshots due to the first snapshot being a full snapshot. However, depending on the amount of changed data since previous snapshots, the length of time for each snapshot creation may vary.
  • Creating snapshots of a disk may reduce disk performance.
  • We recommended that you not create snapshots during peak traffic hours.
  • Manually created snapshots, unlike automatic snapshots, are retained until they are manually deleted.

Procedure

  1. Log on to the ECS console.
  2. Select a region. In the left-side navigation pane, click Instances, and click Manage.

  3. In the left-side navigation pane, click Instance Disks, and click Create Snapshot for the target disk. You can select only one disk at a time, either system disk or data disk.

  4. Enter the name for the snapshot, and click OK.

  5. To view the snapshots, click Instance Snapshots from the left-side navigation pane. You can see the progress and status of the snapshot.
