Couple of observations. First of all, given the price of storage, for backups, I don’t think anything other than mirroring makes sense. Just get 2 big hard drives for your NAS and set them up for mirroring. In the event of a filmier, you can read directly. Next, you don’t have a full backup without offsite storage. Even if it wasn’t a power surge, there could be flooding or fire at a single location. Always remember the basic 3 2 1 rule!
