Copying Images includes two features: Custom Image - Cross-region Replication and Shared Image - Intra-region Replication.
Image Copying Function
Advantages
Note
Custom Image - Cross-region Replication
Helps users quickly deploy identical CVM instances across regions.
You can replicate custom images across regions, and then create cloud servers using the copied images in the new region.
Shared Image - Intra-region Replication
Assists users in copying shared images to custom images for more flexible usage.
The replicated custom image has no special restrictions and possesses the same features as other custom images.
Notes
Custom images can be replicated across regions, and shared images support intra-region replication.
Region Restrictions:
Currently, image replication supports copying from domestic regions to domestic regions, and from overseas regions to overseas regions. If you need to copy an image from a domestic region to an overseas region, or from an overseas region to a domestic region, please apply through Online Support.
Due to data security restrictions in Finance Zones, image copying is supported within Finance Zones but not between Finance Zones and non-Finance Zones.
Image replication is free of charge. But you need to pay for snapshot service for store the copied custom images.
Cross-region replication takes 10 to 30 minutes.
Cross-region replication is not available for full images.
