Copies a DataCache from one region to another region.
Operation description
You cannot directly use a DataCache across regions. You can call this operation to copy a DataCache from one region to another region. This operation is suitable for the following scenarios:
- If you want to use a DataCache across regions and the DataCache exists in Region A, you can call this operation to quickly copy the DataCache to Region B.
- If you directly pull data from a region outside China to a region inside the Chinese mainland when you create a DataCache, the data may be pulled at a slow speed due to network limits. In this case, you can create a DataCache in a region outside the Chinese mainland but inside China, such as the China (Hong Kong) region, and call this operation to copy the data to the region inside the Chinese mainland.
Note
The process of copying a DataCache is equivalent to copying a snapshot. You are charged for the traffic generated during the copy process and the storage of the generated DataCache.
