Google has indexed thousands of backup drives
Each day millions of people across the globe create backups of their files. These backups are supposed to offer a measure of assurance that their files are safe, but that's not entirely true.
In fact, depending on how you've configured the device, your backups are freely available online to anyone who knows what they're looking for.
The following slides contain a few examples of the sensitive information people have stored on a backup drive that was later indexed by Google.
Unfortunately, most don't realize their data is available to the public, potentially offering themselves up as victims of identity theft or similar fraud.
Google isn't to blame either, as all of the backup files archived by the search giant are on networks or devices that were configured to act as public archives of data. But again, most people don't know this is happening.
