Valhalla
This wiki page is a collection of ideas for Project Valhalla.
<SketchCow> Basically, we have this situation where we have stuff that is being threatened, and it's huge, and then it's either not so threatened or it's in a weird quantum state. So, this really stretches the bounds of what IA does. It's a huge amount of data, it's not likely to be overly touched if the originals are up, and IA will spend/lose a lot of money pulling it into their infrastructure. So maybe we can discuss actual, not pie-in-the-sky possibilities of what we can do to have some sort of not-IA pile of storage.
Options
- Commercial/archival-grade tapes
- Consumer tape systems (VHS, Betamax, cassette tapes, ...)
- Vinyl
- PaperBack
- Optar
- Blu-ray: lasts a LOT longer than CD/DVD but should not be assumed to last more than a decade
- M-DISC: Unproven technology, but potentially interesting.
- Flash media
- Wears out quickly, not-so-good long term storage
- Soliciting donations for old flash media from people, or sponsorship from flash companies?
- Glass/metal etching
Non-options
- Ink-based Consumer Optical Media (CDs, DVD, etc.)
- Differences between Blu-Ray and DVD? DVDs do not last very long.
- BitTorrent Sync
- Proprietary (currently), so not a good idea to use as an archival format/platform
- Amazon Glacier
- Amazon Glacier seems like a a great idea, until you realize they mean 1 cent per gigabyte per month. This is $120 per terabyte per year. The transfer out of 100TB would also run over $10,000 the month its pulled from the system.
