[infinispan-dev] Protobuf metadata cache and x-site

[Tristan Tarrant]

It is definitely an internal cache. Because of this, automatically 
backing it up to a remote site might not be such a good idea.

Backups are enabled per-cache, and therefore just blindly replicating 
the schema cache to the other site is not a good idea.

I think that we need a cache-manager-level backup setting that does the 
right thing.
