Fair enough. I go the other way - backing up /usr/bin doesn't matter
much with disk pooling, and my restore method is to boot a live CD,
mount --rbind dev, proc, and sys into /mnt, and then restore over that.
Then chroot into it, install grub again, and reboot.
Installing over a base OS install works too, but it has one weakness:
files that exist as part of the base install, but which don't exist in
the backup, are retained. It also depends on the base OS installer (and
any web dependencies) working, which may not be the case if you are
running a dangerously old distro for some reason.

Another option, or to add to what you've got anyway, is to restrict key
login by IP:

My backuppc keys can login as root, but only from the expected IPs.
Sorry I haven't been able to find your problem. Perhaps use lsof and top
to see what rsync is reading during the backup?
