You'd need something like ElephantFS whose presmise was precisely this. Modern file systems still don't protect user's data the way they should. http://shiftleft.com/mirrors/www.hpl.hp.com/personal/Alistair_Veitch/papers/elephant-hotos/ http://shiftleft.com/mirrors/www.hpl.hp.com/personal/Alistai...
