Back up both sotrage and boot drive? - M.2 and Optical Drive

[bhollehday]

I have two drives on my computer. One is an M.2 that OSX boots on, and the other is an optical 3TB. When Im doing updates, I only need to superduper my m.2 drive correct? I wont screw something up on my storage drive just the boot drive?

Correct. As you shouldn't have any necessary system files on your 3TB drive...
