These agencies send all data to central servers that are backup all over the place. There is no excuse. We need to lock down the server rooms.
Mark Levin had some good phone calls about this. People in IT, etc. One guy used to be in gov’t IT. Said that they have numerous servers that are all “mirrored”, not sure exactly what that means, but one server can go down and another one picks up with all the same information and the user won’t even know.
At the end of each day they would download the servers and save to backup. Every week (or maybe month?) they would do a physical download and ship the physical drive to an underground bunker safe from nuclear or EMP blast. He said they have been doing this since the start of the cold war.
You might end up with a day of lost data, maybe even a week if an EMP hit. But with the “cloud” storage, and lack of any recent EMP’s (!) there should be no significant loss of data.
