Lots of great info here. Unless you have copies of your data off-site, its not backed up. If your home burns down with your expensive NAS with whatever RAID config, your data is gone forever. I RAID & burn to BluRay at home, and I also use BitTorrent Sync to backup my data onto friends/relatives computers in other states. You can create read-only folders so your buddies won't delete your stuff. And if you have pictures of your wife's jigglies, zip them up in a password-protected archive so your buddies won't share them with their buddies. :) TB

Storage - you just need an external HD - a few TB Backup - find a willing friend/relative and use BitTorrent Sync for your photo/video folders.
