Could you tell us what video you are referring to? "excellent Backup video tutorial" is very vague and there are a lot of videos out there that are not made by iXsystems. In fact, I'm not sure I've ever seen one made by them. I know many of the Youtube videos do things that are very risky and not recommended, but people do them anyway. And since its on a youtube video it clearly must be "ok" when it shouldn't be, so users that follow those videos aren't making the smartest of decisions.
