Ask Slashdot: Protecting Data From a Carrington Event? 386
kactusotp writes "I run a small indie game company, and since source code is kind of our lifeblood, I'm pretty paranoid about backups. Every system has a local copy, servers run from a RAID 5 NAS, we have complete offsite backups, backup to keyrings/mobile phones, and cloud backups in other countries as well. With all the talk about solar flares and other such near-extinction events lately, I've been wondering: is it actually possible to store or protect data in such a way that if such an event occurred, data survives and is recoverable in a useful form? Optical and magnetic media would probably be rendered useless by a large enough solar flare, and storing source code/graphics in paper format would be impractical to recover, so Slashdot, short of building a Faraday cage 100 km below the surface of the Moon, how could you protect data to survive a modern day Carrington event?"
