Guys like you are the literal bane of everyone's existence. Unraid is not for backup??? So I can have a disk that allows redundancy or even 2 and that's not a backup solution??? This is why the common man has most of their data on a portable hard drive with no protection on failure. Because people like you make impossible solutions. So what I am supposed to buy 2 or 3 or 4 NASes for backup across multiple continents? How about we start talking about the practical matters for a second? This unpaid solution IS a backup solution for many - and Unraid as a company should be ashamed of shameful bugs - the stakes are high in this business.
I feel like this is why I never recommend unraid to a friend. The complexity, the issues. I recommend Synology instead.
