Replicating an Image Across Regions
Function
This API is an extension one and is used to replicate a private from one region to another region to create ECSs of the same type. This allows you to migrate services between regions.
This API is an asynchronous one. If job_id is returned, the task is successfully delivered. You need to query the status of the asynchronous task. If the status is success, the task is successfully executed. If the status is failed, the task fails.
Huawei Cloud has stopped providing Windows images. This API will no longer be used to replicate Windows images.
Constraints
- The destination region cannot be the same as the source region.
- Encrypted images do not support cross-region replication.
- The size of each image to be replicated across regions cannot be larger than 128 GB.
- A maximum of five private images can be replicated at a time.
- Private images created using ISO files do not support cross-region replication.
