An absolutly righteous article ever Google watcher should read:
For example, the GFS ensures that for every file, at least three copies are stored on different computers in a given server cluster. That means if a computer program tries to read a file from one of those computers, and it fails to respond within a few milliseconds, at least two others will be able to fulfill the request. Such redundancy is important because Google's search system regularly experiences "application bugs, operating system bugs, human errors, and the failures of disks, memory, connectors, networking and power supplies," according to the paper.
