I know this is a bit different from most of the other stories I cover but I saw it and thought it was such an amazing story. Basically this is a video from a couple of people that work at Pixar. While working on the Toy Story 2 movie, someone in the studio accidentally wiped the entire server where the film was stored.
After discovering the backups of the movie were also damaged, there was a moment where the entire movie could have been lost forever. That would be years of animators time down the drain. Until this happened…
