Creating a Full-ECS Image from a CSBS Backup
Scenarios
Create a full-ECS image from a CSBS backup. This image can then 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.
- 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 it.
- If you use a full-ECS image to change an ECS OS, only the system disk data can be written into the ECS. Therefore, if you want to restore or migrate the data disk data of an ECS by using a full-ECS image, you can only use the image to create a new ECS rather than use it to change the ECS OS.
Constraints
- When creating a full-ECS image from a CSBS backup, ensure that the source ECS of the CSBS backup has been properly configured, or the image creation may fail.
- If an ECS is in Stopped state, do not start it when you are using it to create a full-ECS 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.
- A full-ECS image cannot be replicated within a region.
- Cross-region replication of full-ECS images is only available for certain regions.
If a full-ECS image cannot be replicated to a different region, you can use it to create an ECS, use the ECS to create a system disk image and a data disk image, and replicate the images to the destination region.
A full-ECS image created using an ECS backup can be replicated from the region where they reside to another region, but the replicated full-ECS image cannot be replicated across regions again.
Procedure
- Access the IMS console.
- Log in to the management console.
- Under Compute, click Image Management Service.
The IMS console is displayed.
- Create a full-ECS image.
- Click Create Image in the upper right corner.
- In the Image Type and Source area, select Full-ECS image for Type.
- Select CSBS Backup for Source and then select a backup from the list.
Figure 1 Creating a full-ECS image using a CSBS backup
- In the Image Information area, configure basic image details, such as the image name and description.
- Click Next.
- Confirm the settings. Read the image disclaimer and select I have read and agree to the Image Disclaimer, and click Submit.
- Switch back to the Image Management Service page to monitor the image status.
When the image status changes to Normal, the image creation is complete.
Follow-up Procedure
- 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.
NOTE:
When you use a full-ECS image to create an ECS:
- The system and data disk information defaulted by the image will be automatically displayed.
- If the full-ECS image contains multiple data disks, it takes some time to load and display the disk information.
- If you use a full-ECS image to change an ECS OS, only the system disk data can be written into the ECS. Therefore, if you want to restore or migrate the data disk data of an ECS by using a full-ECS image, you can only use the image to create a new ECS rather than use it to change the ECS OS.
- If you want to share a full-ECS image with other tenants, you must migrate the associated backup to CBR first because only full-ECS images created from CBR backups can be shared.
