A brief update:

The current amortized cost of making 10 nickel discs (each with 10,000 pages in a 100x100 grid) is around $500 each. They can also make polymer copies for much less that are likely stable for at least a century.
The amortized cost is closer to $600 for nickel disks and $150 for polymer.
Back to the near term : can someone tell me the rough cost per GB and expected lifetime of the backups our colo uses? (I would guess $1 and 20 years.) Are there full offsite backups?
I would feel better if people would help update http://meta.wikimedia.org/wiki/Contingency_planning ...
