Cross-region Replication of the Image
Overview
The cross-region replication of images is applicable for the cross-region instance deployment and the cross-region data backup. You can replicate the custom image in a certain region to other Baidu AI Cloud regions, and create the BCC instance in corresponding regions through this image, so that the BCC instances of the same environment is deployed in different regions.
Application Scenarios
The image is a regional resource, and the custom image belongs to the region where it is created. The usage of different scenarios is shown in the table below.
| Scenarios | Operation Steps | Description |
