High Scalability - High Scalability - How Google Backs Up the Internet Along With Exabytes of Other Data

Local copies do not protect against site outages.
If you have a flood in your server room RAID doesn’t help. Google File System (GFS), used throughout Google until about a year ago, takes the concept of RAID up a notch. Using coding techniques to write to multiple datacenters in different cities at once, so you only need N-1 fragments to reconstruct the data. So with three datacenters once can die and you still have the data available.- http://highscalability.com/blog/2014/2/3/how-google-backs-up-the-internet-along-with-exabytes-of-othe.html
