"What's happened with the customers data? It shows up as incomprehensible garbage on the screen!" "Well, you see - imagine a collection of buckets with water standing on top of each other." "Uh, yes?" "The water is flowing into the topmost bucket, slowly filling it up, so when it is full the water fills up the next bucket. This how we designed our state-of-the-art RAID, sir.

"Oh my god. Please tell me we have a backup of this." "Okay, so image a bucket pipe going to each.." "Just call the plumber and stop wasting my time!" "At once, sir!"
