Interesting article, being involved in IT as a DBA I see all kinds of redundant storage schemes. Currently we are using Solid State Arrays which have excellent access speeds. The cost is something that might make a major US studio hesitate, never mind the Anime studios.
Last week I had an experience with Blu-Ray that I'd never had before. A new copy of Yurikuma Arashi had the first Blu-Ray disk be unplayable in two of the 3 Blu-Ray players we have, the third would only pull up the menu and would not go further. So, it is possible for there to be issues even with something that is nominally robust like Blu-Ray. Mark Gosdin |

"Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway." —Tanenbaum, Andrew S. (1989) I assume these must be huge files, so there's gotta be a cutoff point where the digital transfer just can't compete on either time or price. Are overseas transfers physical? |

Sounds more like an issue with mastering, rather than the reliability of the disc. What's on the disc is there for good, but dud data was written to it to begin with.
I assume that would be a complex equation with filesize, urgency, cost and how well the internet connection's behaving itself at the time being the variables. |

Is the DRM/encryption on Blu-Ray discs going to make that problematic for future archivists? Even assuming the DMCA doesn't make ripping Blu-Rays illegal well into the 21st century… |

Archival material shouldn't need high access speeds... At least it used to be that the further you got from current needs, the slower and cheaper the storage media became. |

I don't know how other companies do it, but I had once worked with shooting a movie, and the producer found that it was most convenient to have the lead editor right there near where they were shooting so they could give the footage to him and work on it. They were saved via a large amount of external hard drives, which were carried around manually, but because the editor was there on-site, they were only carried mostly to remove them from the shooting site and stored at the headquarters. The cameras they used created video whose file sizes were sometimes in the gigabytes per second. They would go through about 5 terabytes of footage shot per day, which amounted to about 90 minutes. |

I'd be more worried about storage of the archives, anime has one of the worst histories when it comes to storing archived masters, all manner of accidents, misplacing of masters, writing over masters (I don't think this happens anymore), and the like. US TV was the absolute worst at this for the most part until the 80's and 90's when they wisened up.

Now that we're living in the digital age I thought that it was easy to archive Anime series but I guess that I was wrong.

I wouldn't count on BluRays as some kind of last resort when the master tapes get lost or something. Like with any other disc (CD or DVD) their material decays and is most likely to get unreadable after some decades. That's also the reason for developing things like M-Discs (https://en.wikipedia.org/wiki/M-DISC).
Currently there just isn't any storage format or media where digital preservation for more than 30 years or so can be guaranteed. Digital data is the nightmare of archivists. It's way more complicated AND expensive to preserve than things like written documents, 35mm film etc. |

Rather than storing them in a Film Canister or HDD and let them to rot, they should do periodical "spring cleaning" to transfer the files to another storage device so the media remains in as pristine condition as possible and so on and so on.
That would require hiring a couple of people to do the labor, but it sure is better than ending up with decayed quality video should the need to remaster happens. |

Do they backup the actual production files (like NLE projects, After Effects files, whatever they use to draw, vocal performances, music, sound effects, Pro Tools session data, etc) or just the final video and audio mix?

I read that some Hollywood studios are still storing their movies on archived 35mm film prints, even for films shot/animated digitally. It's just that reliable.

Japanese anime is compressed on blu-rays?
Even though they only put 2-3 episodes on a disk? |

Even if only done occasionally, that's still pretty costly each time they do it. It's definitely the one way to guarantee nothing will ever be lost, but I'd bet it's also the most expensive, if only due to the large amount of materials consumed over time. |
