If the PC was powerful enough and there was enough storage space, is it possible to download an entire website in one go and store if offline?

Its probably silly but I'm thinking that, in the catastrophic event Jovitalk went down/offline for whatever reason, theres way too many useful threads on here for them to be lost forever. This community built up a hell a lot of information and discussion over the last decade (Setlists, info about rare releases, Sebs hoaxes ) and I'm wondering if there was a way to safeguard it all?
