well I have encrypted off site copies at my partners house in London and my other partners parents house across the state. just be poly!
as far as the two goes, I have copies on physical spinning platters and copies of critical data on ssds.
as far as the one is concerned, I have separation of copies from the Washington coast to London so it would have to be a world ending disaster to cause me to lose all copies of my data.
that being said it has taken me the better part of a decade to get this far and they are all cold copies so they require maintenance to keep up to date. that being said they can't be infected from the internet very easily that way
Yeah, you are basically just making a DAS there I guess
