I need a product that will back up data automatically at night for my 3-4 computers. I need this to be done wirelessly. I have a folder on each PC named Data. I want this folder backed up nightly. I would ideally like to be able to access backups of the folder for the past 5 days, and then also one weekly backup from the past 4 weeks.
I also want to be able to store an image of each PC on the external drive for emergency HDD recovery.
How can I get this device on my WiFi?
I am thinking a 4TB MyCloud will do all of this functionality. All PCs are win 7 or 8.
