Before upgrading OS should I backup EVERYTHING?

I back up just my personal files monthly. I'm going to upgrade from OS 10.6.8 to 10.12 and I see that "it is recommended that you back up your Mac before upgrading". Does that mean that I should I backup EVERYTHING on the Mac HD? This would include Applications, Library, System, etc. folders as well as my personal files.

Thanks, Richard
