Genius needed - please make system restore function

Hi, as the title says, I(and probably many others) would very much like a system restore function that could be added to GRUB menu, so that in case an update or other things went wrong, then the system could be up and ruing again in no time and ones personal files were safe. All the backup programs that work from inside Ubuntu are no good if you caot get to the desktop or the prompt.

Personally I'm using Peach OSI which is built upon Xubuntu 14.04 LTS and later will be updated to 16.04 LTS - I took the jump and are only using linux now and no more windows, only a few programs I were using before don't have linux alteatives and I use them on my other laptop.

Hope someone can make this happen

With kind regards
