Hi all !!

Is it possible that someone make a video to show how to back up and restaure a back up wallet please ?
Cause i try to restaure my back up wallet but it doesn't work..also i think it will help many people like me that doesn't have a lot of competences in pc, and would like to remove their Bay from exchanges and save their wallet in case they lost it.
So if someone can do it it will be very helpfull !!
