"DFAS also could not make accurate year-end Army financial statements because more than 16,000 financial data files had vanished from its computer system."

I am impressed. I did an internship at a financial company and helped do end of month closing balance adjustments. We had a onsite and remote paper copy storage of each document, an onsite server room that hosted a copy, a off site tape copy and an offsite digital back up. Hard to think of what must have happened to get that level of mishap.
