Solar Storm in a Year or Two

It's coming and it might be disastrous for electronics...or not. (HT: Instapundit.)

Will there be any warning, or do solar storms travel basically at the speed of light? Are inexpensive Faraday-cage-like mitigation measures available? If nothing else, maybe I should bargain hunt for DVDs and back up my archives to them. 200 DVDs will almost hold a TB: backing up would be onerous, but not prohibitively so. (Since DVDs are not magnetic storage, they presumably would not be affected by EMPlike events, but this bears explicitly checking in the spirit of due diligence.)
