  • Google staff have to go through a series of identity checks to gain access to the data center building and different parts of the facility.

    Staff at the datacenters carry identity badges that are made using lenticular printing, which makes them difficult to forge.

    In some of Google's datacenters, staff identity is checked by scanning their irises, as seen here.

  • 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.

  • Google tracks the location and status of each hard drive in its data centers.

    If there is a problem with a hard drive, it's reformatted and retested. If the drive does not pass these tests it's then removed, and the data on the drive is overwritten and verified to make sure it contains no customer data.

    pretty basic stuff.

      You'd be surprised. I've been to datacenters where security wasn't nearly on par with what google is doing. I'm certain that places like Google and Microsoft have good reason to have such security, but you'd think certain public sector datacenters would care just as much about their data.
    • I agree. I'm guessing most of those high security

      @dbeecher@... <br>procedures are for Google's own data (software, search algorythims, corporate data, ect) while the customer data is pretty much industry standard levels.<br>
