We&#x27;ve been doing it for a long time. It&#x27;s called some reliable servers in multiple locations with copies of the same data plus some offline backups (esp tape). There&#x27;s many non-technical, Fortune 500 companies whose data has lasted longer than Amazon&#x27;s existence. Cheapest version of this involves two high-capacity boxes at two locations each with maybe a colo agreement. Let&#x27;s you keep replacing stuff as servers and drives fail. I&#x27;ve even done it with embedded boxes (VIA Artigo&#x27;s) in the past where data volume wasn&#x27;t high.
