Copying data between clusters

   - Is it possible to use the built-in backup/restore functions of
   riak-admin to copy data between clusters?  The scenario is that we have
   separate test and production environments, each with separate riak clusters
   of different sizes and configurations.  Every so often we'd like to copy the
   data from production into test.  Can I run 'backup all' in prod, then run
   restore on the resultant file in test, and have everything work?  Or does
   restore only work on the same cluster configuration that the backup was
   performed on?  What's the easiest way of doing this?


   - I've noticed that backup takes a very long time, and results in a file
   that is much larger than the actual cluster data directories of the cluster.
    Is this normal?


   - Not related to backups, but how do I configure the global replication
   count of the cluster?
