Help I am clueless about backing up my PC. I need to sort it and I need a very simple solution, hopefully just something to plug in and automatically back everything up and ideally keep backing it up with minimal intervention. There's not much stuff really just word documents mainly. I have a SanDisk thing currently but I don't really know if I have used it properly and have now forgotten my password and am locked out anyway! Please advise me what I should buy instead and where from! Thank you
