IIRC rsync will make a FULL copy, meaning that files that don't change

For default and reasonable options, rsync makes full copies of only
those files that don't already exist. Files that already exist and
are identical are not copied. If you keep copies you get new
complete copies for any files that changed, I'm not sure if rsync
transfers the deltas to reduce bandwidth but definitely not final
disk space.
The advantage of subversion is that it only saves the deltas.
That is worth the savings, through I have never tried subversion to
backup whole disks. It is possible without individually "checking
in" all the files one at a time. If I could script subversion to
back up disks and file structures that would be interesting.
