Every electrical device with a circuit board or wiring would become nothing but paperweights. We'd be thrown into the stoneage worldwide. The only reason the Carrington event didn't was because we didn't have a world full of tech back then. Storing data offline would be redundant....... you wouldn't have a working PC or laptop to access the data.......also, you stored it on a HDD/FLASH device......so there is circuitry, magnetic discs etc.......you're screwed anyway. Unless you own a very deep cave with its own power source and all your tech was housed in said cave and within a Faraday Cage.......you'd still be pretty screwed.
