How do I initiate internal drive backup?
I have never backed up my computer on its internal hard drive, I know it's horrible (gasp!) but I need to know how to initiate the process. I have a lot of my files backed up onto external hard drives, but just need to back up my computer on its own internal drive. How do I do this? I am not a computer person, so dumbed-down step-by-step processes would be much appreciated. Thank you!
