I think for Linus Media Group the main "meta" issue is that they don't have a dedicated member of staff to handle boring day-to-day IT / sysadmin tasks that you don't make videos about. A video about building a crazy storage server is content for a video so gets done, but somebody needs to make sure its still working / updated, and you don't make videos about routine maintenance that so its forgotten. Although everyone else can learn the important lesson that RAID / ZFS isn't magic and you need to have stuff setup correctly and monitored. The fact that RAID isn't a backup as well[1]. [1] Although if the LMG servers affected are just for data hoarding raw footage that is unlikely to be needed again, it's possible the risk / cost balance pushes away from backups and just relying on RAID, but that's a niche case (and they lost the gamble...).
