Why is it "illegal" to backup my games?

Okay. So, backing up isn't illegal.

But in order to play backup, I have to illegally mod my system?

Is it legal or not?

Modding your system isn't illegal. You can mod your system any way you damn well please. Lots and lots and lots of people play their Wii games off of external hard drives.
