Scenarios

You can use a Cloud Backup and Recovery (CBR) backup to create a full-ECS image, which can be used to create ECSs.

Background

• The Cloud Backup and Recovery (CBR) service provides backup services for EVS disks, ECSs, and BMSs, and supports restoring data of servers and disks using backups. If you have created a backup for an ECS using CBR, you can use the backup to create a full-ECS image.
• If you use a CBR backup to create a full-ECS image, you will only be charged for the CBR backup. For detailed pricing, see Cloud Backup and Recovery in Product Pricing Details on the HUAWEI CLOUD official website.
• When deleting a full-ECS image, you can choose whether to delete the associated CBR backup. If you choose not to delete the CBR 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 CBR backup, ensure that the source ECS of the CBR 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 CBR backup can be used to create only one full-ECS image.
• A full-ECS image created from a CBR backup can be shared with other tenants. However, if it is a shared CBR backup, the full-ECS image created from it cannot be shared.
• 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 Cloud Server 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 image is created successfully.

Follow-up Operations

After a full-ECS image is created, you can perform the following operations:

• If you want to use the image to create an ECS, click Apply for Server in the Operation column. On the displayed page, select Private image and then select the created full-ECS image. For details, see Purchasing an ECS with Customized Configurations.
  

  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 the image with other tenants, click More in the Operation column and select Share from the drop-down list box. In the displayed dialog box, enter the account names of the image recipients. For details, see Sharing Specified Images.
• If you want to replicate the image to another region, click More in the Operation column and select Replicate from the drop-down list box. In the displayed dialog box, retain Across Regions and set other parameters such as Name and Destination Region. For details, see Replicating Images Across Regions.
