This story serves as a reminder that you should regularly back up your data. It is hard to believe that the U.S. Air Force Inspector General and Lockheed Martin didn't use common sense when it came to extremely important data like this. Defense One and others are reporting that the USAF lost its records of 100,000 investigations in their Automated Case Tracking System due to some kind of file corruption that neither Lockheed Martin or the Air Force have been able to figure out. Apparently Lockheed Martin spent two weeks trying to fix the problem before informing the Air Force, but had to own up to their failure when the issue proved insurmountable. The Air Force was said to have been informed on June 6th, and has since requested the help of the Pentagon’s cybersecurity operators as well as private contractors.
