Here is my situation. I am about to buy a 3TB internal hard drive to back up my NAS, my HTPC and my Laptop. My NAS is a POGOPLUG running archlinux running a samba server, torrent app, and sickbeard. I use the attached hard drive to store all my movies, tv shows, and music. It has 1 1.5TB hardrive attached to it. My HTPC is running PLEX and has a single 1TB hard drive (BTW It is running 24/7 and has Windows 8.1 Pro installed as the OS). My Laptop has a single 256GB Samsung 840 Pro. I am just wondering if there is a a built in windows service or a third-party program (Would prefer a built in Windows solution), that will do a weekly 1:1 Backup of each of those 3 drivers (NAS, HTPC, and Laptop). Thanks!
