There's a phrase the Army uses: "One is none, two is one, three is better." You've put a lot of work into writing the content for your Ghost blog, but if you only have your content stored on this one server, a simple storage failure could wipe out years of work. Remember: One is none. Protect your time investment by backing up a second copy of your Ghost content to your unRAID server. This same process can also be used to mount any other unRAID share on an Ubuntu server, not just for Ghost content. I even use it to backup my RPi NGINX reverse proxy server.
