So much this. In recent years, we had one large library with historic books and one city archive of a 1000 years largely damaged and destroyed by a fire and a building collapse.
These kind of heritage all should be digitized in high-res and put online so that a) all people have access to this heritage and b) the online archives could be easily replicated. If there were just 10 archives for a country like Germany, and all these archives would replicate each other, this would mean a huge level of safety. Add Amazon glacier or something to it, and we have a good chance of preserving this important part of history.
