I setup deduplication between hosts with rsnapshot as you do. But it was
a small gain in my case as the larger part was users data, logs and the
like. So always different between hosts. I gain only on system
files. Mainly /etc as I don't backup binaries and libs.
I almost never move large directories. But if needed it's easy to move it
also in rsnapshot directories.
