Not really. The way the other programs I mentioned (dirvish and
faubackup) handle it is they maintain a full copy of the data from the
backup host. They then use hard links between files when no change is
made. Changed files are made from scratch and then, if they don't changed,
are linked to, so very little space is lost.

Keeping specific versions then becomes trivial, since every version is a
full.
