Every 2 days, Google generates approximately 5 exabytes of data!!
1 exabyte (EB) = 1 quintillion bytes
(quintillion = 1,000,000,000,000,000,000 = 10006 = 1018)
or, for the non techies, great quote from Eric Schmidt:
"Every two days now we create as much information as we did from the dawn of civilization up until 2003"

How on earth do Google backup and synch all that data across their datacentres! Imagine having to do a restore
