Back-up for your back-up. Wise as it is to store all of your most important and treasured electronic files on an external hard drive, what happens if something happens to that? Panic not, for the ioSafe Solo G3 Hard Drive is nigh-on indestructible, waterproof and fire resistant, if it is somehow destroyed, chances are you - and the rest of the world - won't have survived either, so don't worry about it.
