Scenarios

You can use a CSBS backup to create a full-ECS image, which can be used to create ECSs.

Background

• If you use a CSBS backup to create a full-ECS image, you will only be charged for the CSBS backup. For detailed service pricing, see Cloud Server Backup Service in Product Pricing Details on the HUAWEI CLOUD official website.
• When deleting a full-ECS image, you can choose whether to delete the associated CSBS backup. If you choose not to delete the CSBS backup, you will continue to be charged for the backup.
• To restore or migrate data disk data by using a full-ECS image, create a new ECS to do it instead of changing the OS of an existing ECS.

Constraints

• When creating a full-ECS image from a CSBS backup, ensure that the source ECS of the CSBS backup has been properly configured. Otherwise, creating ECSs using the full-ECS image may fail.

  For details, see What Initial Configuration Needs to Be Performed on the ECS, BMS, or Image File Before It Is Used to Create an Image?

• A CSBS backup used to create a full-ECS image cannot have shared disks.
• Only an available CSBS backup can be used to create a full-ECS image. A CSBS backup can be used to create only one full-ECS image.
• A full-ECS image cannot be exported, published in Marketplace, or replicated within a region.

Procedure

1. Log in to the management console.
2. Under Computing, click Image Management Service.

   The IMS console is displayed.

3. Click Create Image in the upper right corner.
4. In the Image Type and Source area, select Full-ECS image for Type.
5. Select CSBS Backup for Source and then select a backup from the list.

6. In the Image Information area, configure basic image information, such as the image name and description.
7. Click Next.
8. Confirm the parameters. Read and select the agreement, and click Submit.
9. Switch back to the Image Management Service page to view the image status.

   When the image status changes to Normal, the creation is successful.

Follow-up Operations

• If you want to use the full-ECS image to create ECSs, click Apply for Server in the Operation column. On the displayed page, create ECSs by following the instructions in Elastic Cloud Server User Guide.
  

  If a full-ECS image contains one or more data disks, the system automatically configures data disk parameters when you use the image to create ECSs.

• If you want to share a full-ECS image with other tenants, you must migrate resources to the CBR service because only full-ECS images created from cloud server backups can be shared. For details, see How Do I Share a Full-ECS Image Created from a CSBS Backup with Other Tenants?
