Remote Backup

I supposed your way to be a second NAS (though this would be an USB disk in a bank safe for you I guess). I meant this solution to be a place where you have full control about physical and logical environment.

I also dislike the word cloud. I just feel like it means nothing. My definition being anything that can be accessed at more than 2 locations (that you don't need to know to access the resource) via internet... This would mean that any website out there is part of a cloud... I may have a wrong definition though.

I actually know what information security is, how to manage and improve it. So I can assure you that you are not old fashioned (and if you are everyone should be). There are many enterprises out there that store archive tapes in bank safes. If you want to work on something very critical, the computer shouldn't be physically connected to the network if you ask me. You seem to know a bit about security, so this quote won't surprise you (if you don't already know it) :

The only system which is truly secure is one which is switched off and unplugged locked in a titanium lined safe, buried in a concrete bunker, and is surrounded by nerve gas and very highly paid armed guards. Even then, I wouldn't stake my life on it. -- Gene Spafford, Director, Computer Operations, Audit, and Security Technology (COAST) Project, Purdue University

For day to day backup you need something more flexible I think. Driving 200km a day is not very practical for daily backups (100km being the minimum distance recommended for remote backup, because of natural disasters). That's why enterprises tend to invest in specific network configurations (MPLS, dedicated fiber...). My question was more aimed to consumers and small business owners though, as big enterprises have budget and skill to go with complicated and costly setups.
