This sounds as nothing more than a mirror with one disk beeing a remote
file.
And this is not really a new idea - remote mirror has a long standing
tradition.
You can already configure these things with GEOM right now.
But this is in no way a backup, this just saves you from disk failures
which is the purpose of a mirror.
What is missing is history in the remote image so that one can access
older contents.
