Google takes a variety of steps to protect customer data stored on its data center hard drives, a rack of which are seen here.
Customer data is stored in multiple locations, the files that store the data are given random file names and are not written in clear text, so they are not easily readable by people.
If there is a fire or any other disruption at the data center, customers are able to access their data from another data center location.
