That's bad luck, and precisely the reason why I suggest you have a more
robust backup strategy. I don't see how having /root on a partition
helps at, especially given the fact that no vital user data is stored on it.

Well that's fine, if you feel more comfortable, then keep / serparte,
you will sacrifice the ability to resize it though.

Rsync only copies changed files, I use:
rsync -av --delete --delete-excluded --exclude=vmware /home
