If you want to create an ECS instance that has the same operating system, software applications, and data as an existing instance, you can create a custom image and use it to create an ECS instance.

Background information

Procedure

  1. Log on to the ECS console.
  2. In the left-side navigation pane, click Instances.
    You can also click Images to find the target image, and then click Create Instance in the Actions column.
  3. In the upper-right corner of the Instances page, click Create Instance.
  4. Follow the instructions in Create an instance by using the wizard. When creating an ECS instance, note the following:
    • Region: Select the region where the image is located.
    • Image: Select Custom Image or Shared Image, and then select an image from the drop-down list.
      Note If the selected custom image contains more than one data disk snapshot, an equal number of cloud disks are automatically created to function as data disks. By default, the size of each data disk is equal to that of the source snapshot. You can only increase the size of a data disk. You cannot decrease it.
  5. Confirm the order.
