The guy that explained it to you is on the right track, but a little bit mistaken. Yes, they do have millions of servers, however, not every single
one of those servers has every piece of data. It takes thousands of servers in a cluster to make up a single data center, and the information that
Google has is spread across all of those servers.
They likely only have a handful of data centers throughout the world, and each one would probably have a copy or two (for redundancy) of pieces of
data.
Also, not everything is indexed, for example, Google only indexes a thumbnail sized version of pictures, with a link to the full size picture on the
server it came from.
Between all of the major search engines, with all of their data centers, you would be looking at a handful of copies.
But... maybe the CIA and NSA have servers that are constantly copying information to servers... but we'll leave that discussion for a different
thread
