I couldn't watch the video because I'm on a train - however, I worked at Pixar from 2002 - 2008, so I'm pretty sure I know exactly what this video is about.
This story was legendary inside the studio - I never thought it would get outside the gates. In some ways, the fact that this had happened in the past, when the assets for a film might actually fit on a single workstation, was great.
Everyone was more careful. The Systems group was great at backups, recovery, and did an amazing job the whole time I was there, and I'm sure this story always sat in the back of their minds as a reminder of why they spent all the extra time and money.
The one time I accidentally locally deleted a day's work, I had a recovery in my home directory in less than an hour.
