I picked up a Zyxel NAS326 2 drive NAS before black friday and I've finally gotten a pair of drives for it. I got a pair of HGST Deskstar NAS 3.5" 4TB 7200 RPM drives on sale from Fry's. This is my first time setting up a NAS like this and the first time I had the money for a raid set up. I set it up as a raid 1. I'm looking for recommendations on backup software. I saw that windows 10 has a built in option and I've used cobian as well. I like free options if they are available, but will consider paid options.
