My needs/approach is similar to yours. What I am now doing is I have a MondoRescue DVD containing / (with the exception of /home as that changes too often) to allow for a bare-metal restore; then I have an rsync of everything except /proc/ /tmp/ /mnt/ /sys/ and /dev/ (which is handled by udev anyway). (Mondo takes about five hours to backup/verify about 6GB of data using normal compression, rsync took about five hours to do inital sync on 93GB.) Now in theory, (I have done the bare-metal restore using mondorescue before... so I /know/ that works) the procedure would be restore the system to a working state via mondo, log in as root, rsync everything back from rsync mirror. Now if I understand everything correctly that would put me current as of the rsync time.
