A command entered in the "master machine" where the animation for Toy Story 2 was stored deleted 90 percent of the work the Pixar team had done on it. As Mental Floss describes, "A plan was quickly hatched to restore the data from a regular backup, which meant that only half a day of work would have been lost. But the backup system had failed. Pixar, incredibly, did not have a copy of the Toy Story 2 files on its servers." Fortunately, the film's technical director had a copy she had been working on from home, and much of it was restored.
