Managing Private Images
Private Image Lifecycle
After you create a private image, you can use it to create cloud servers or EVS disks. You can also share the image with other accounts or replicate it to other regions. Figure 1 shows the lifecycle of a private image.
Creating an ECS from a Private Image
After a system disk image or full-ECS image is created, in the image list, you can locate the image and click Apply for Server to create new ECSs.

Exporting an Image
You can export private images to your OBS bucket and download them to your local PC for backup.
Related operations:
Encrypting an Image
You can create encrypted images to improve data security. KMS envelope encryption is used. Encrypted images can be created from external image files or encrypted cloud servers.

Replicating Images Within a Region
You can replicate an image within a region to make encrypted or unencrypted copies or enable some advanced features (such as fast server creation).
Related operations:
Replicating Images Across Regions
You can replicate private images created in one region to another region. Cross-region replication can be used together with image sharing for cross-region, cross-account image replication.
Related operations:
Tagging Images
You can tag your private images for easier management and search.
Related operations:
Exporting an Image List
You can export the public or private image list in a given region as a CSV file for local maintenance and query.
