ya many of those things are quite simple & can be easily achieved by having multiple remotes with one sitting in a common NFS mounted drive (I've even done sshfs & it all works fine). far as backup is concerned it just a tarball to nfs. alternatively one might look at something like gitfs. My problem with such 'overly integrated solutions' is that they work until they dont. if git were to do it the okay but what if you are dealing with multiple git repos? what if some of them are gitfusion repos from perforce backend? IMHO simple & deterministic (as in deterministic to human mind) is better.
