None of it will matter. That said, short term FUBAR can be mitigated. I have a semi-portable solar setup that currently runs my internet, NAS, Fridge and to some degree, the A/C.
To prep for the serious mess, I have to get Faraday bags for my server, drives, and solar generator and have enough time to bag everything before the EMP hits.
I have survival guides in book form as well as on the NAS, and I work the land enough to bring the soil into balance and build its fertility, plus feed the bees so they’ll be there when I need them.
