@stefano Absolutely. Not as life critical as your experience but I was the IT manager of a broking house in the City of London. Absolutely everything was backed up, both on site behind fire walls, literal & programmed. We also had off-site secure back ups. We were bombed out by the IRA twice in the eighties, up and running in two hours. Just goes to show & privately, I wouldn't put a damn thing up to the cloud. An 'accident' waiting to happen IMO
