This could be very bad if for example like me you don't allow games to use cloud saves and stuff. An example would be for me Rocket League for one. The whole games items and levels would be lost totally if i lost my docs folder. I do keep a back up of my Game saves on a 3rd HDD just in case of HDD failure and i keep updating it manually every time i get new stuff. For some reason i just hate Cloud Saving stuff but i'm starting to realize that i might have to bite a bullet and start using that method of saving.
