Already there with multiple towers and lappies that dual boot with W7 or 8.1 and Linux or BSD. Multiple disk images on HDD's, Flash drives, and M-Disks with incremental back ups for all. Windows does not go online, only Linux/BSD. Back up lappies in EMP proof cabinets with solar panels. Firewalls battened down and all all unnecessary services disabled or uninstalled. Along with all the usual prepper stuff including shortwave. I'm ready for the shit, man.
