This is a fine idea, but I don't think support for this should be added to rsync. Instead, I suggest that you use rdiff-backup ( http://www.nongnu.org/rdiff-backup/ ), a backup tool that stores an ordinary latest snapshot of the source along with reverse deltas for previous snapshots and redundant attribute information both in its own format.
