2-4tb of your Wife's pics? Sure 
. Just get a 4tb drive and keep it with a friend or family member, but maybe you don't want them seeing your massively impressive porn collection? 
4tb drives cost a little over £100 in the UK and you can get 'em cheaper in the US and I would rather keep them myself than trust a cloud site with them. You could also get a blu-ray burner and burn them to them instead. Think they hold about 25gb per disc.

I work at a AD Agency so theres a lot of my work as well as commercial videos in raw format. My wife's a photographer as well as both our computers need backup regularly. But you're right I could buy another NAS and have it mirrored at some of my folks.
Thanks for the tip please.
