 The work done on the film to date was nearly lost in 1998 when one of the animators, while routinely clearing some files, accidentally started a deletion of the root folder of the "Toy Story 2" assets on Pixar's internal servers.Associate technical director Oren Jacob was one of the first to notice as character models disappeared from their works in progress.They shut down the file servers but had lost 90% of the last two years of work, and the backups were found to have failed some time previously.
