Copying data between clusters

I can't answer your replication questions -- don't have a lot of experience with it yet -- but I can take a stab at setting the global replication setting.
If I'm understanding correctly I believe you're referring to the N value. N controls how many replicas of an entry Riak stores, in total, around the cluster. Docs on tuning this value can be found here: http://wiki.basho.com/display/RIAK/Replication

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?
