Using a Backup to Create an Image

CBR allows you to create images using ECS backups. You can use the images to provision ECSs to rapidly restore service running environments.


  • The following operations have been performed:
  • The backup is in the Available state or in the Creating state which is marked with Image can be created.

    Once a backup creation starts, the backup enters the Creating state. After a period of time, a message stating "Image can be created" is displayed under Creating. In this case, the backup can be used for creating an image, even though it is still being created and cannot be used for restoration.

  • The backup contains the system disk data.
  • Only ECS backups can be used to create images.


  • Images created using a backup are the same, so CBR allows you to use a backup to create only one full-ECS image that contains the whole data of the system disk and data disks of an ECS, in order to save the image quota. After an image is created, you can use the image to provision multiple ECSs in a batch.
  • A backup with an image created cannot be deleted directly. To delete such a backup, delete its image first. If a backup is automatically generated based on a backup policy and the backup has been used to create an image, the backup will not be counted as a retained backup and will not be deleted automatically.
  • A backup is compressed when it is used to create an image, so the size of the generated image may be smaller than the backup size.
