Sad story: the world's largest TV show/movie collection including unreleased films, pilots, etc at ~ 5PB has been lost. People in Hollywood would mail this person stuff to make sure it didn't get lost. Welp, at least that copy is lost now.
a bad storage controller wiped it all out. I don't know the specific controller or configuration, but ZFS was used and I'm supposing the root cause was a ZFS scrub making ZFS think there were errors to correct, so it tried, but it just kept corrupting more and more data because even the corrected writes were wrong once they finally hit the disk
It was being backed up, but the backups got corrupted too because it wasn't noticed in time.
