When backing up Ubuntu 12.04 is it necessary to backup system files outside of the home folder? I have had a GRUB installation become corrupted by a subsequent update. I need a strategy to recover from errant updates. That is, to roll back my updates.

I won't speak on whether or not you need to backup system files but if you want roll back on your entire system you could do something crazy with bup and dd. We do something similar with our databases to give use almost infinite roll back capabilities. But this is obviously on a smaller scale.
