I can see this making a lot more sense for photo/video. The Holocron approach is neat when your truly irreplaceable data fits on a handful of discs, but I would not want to burn and manage dozens of them every year
Yeah I'm tending to shoot around 1TB of data per wedding I cover now that video is in fashion for it. Thankfully it's exactly the sorta thing tape is suitable for - once I'm done I can just archive a couple of weddings off per tape. It's generally very unlikely I get requests for that data later (once they've ordered prints) so doesn't make much sense keeping it on spinning disks in my NAS.
