2Down on Googles Server Farm
Google each year custom-crafts thousands of servers running a barebones version of the Linux operating system. Some have said Google owns and operates more than 1 million servers, powering search, Google Maps, Google apps and Google Checkout, among other Web services. Google said this customized approach provides a computing environment that is far less prone to security vulnerabilities.
Google data centers, such as the one in Moncks Corner, are secured with guards, gates and checkpoints. If you’re thinking it’s the sort of security you’d envision for a government building, you’d be correct, only Google’s facilities lie in remote parts of the world. Security guards watch the grounds 24/7.

As for the data security itself, Google Apps customer data is stored in multiple locations. File names are random and are not readable by humans to protect data privacy. Failing hard drives are brought here for reformatting. Data on a failed hard drive is overwritten and checked to ensure the data has been destroyed.
