Detailed Description

Copy all files in one container of one backend to another.

This can also be used to re-shard the files for one backend using the config of second backend. The second backend should have the same config as the first, except for it having a different name and different sharding configuration. The backend should be made read-only while this runs. After this script finishes, the old files in the containers can be deleted.
