In general, just the small file. There are a couple of exceptions, so if
you don't see that happening you may not be doing anything wrong. If you
add a new RO site and re-release, all of the data gets pushed to all
sites. There also might be some corner cases w.r.t. how quickly you
create some files relative to when you release, but you shouldn't see
the whole volume need to get shipped over the wire.
