I once pressed my boss into having off-premises storage of documents so we could still manufacture product in a new facility if the current facility burnt down. Unfortunately, someone started the habit of sending the primary documents to the same facility if the product was deprecated. One day, that off-premises facility burnt down and all the contents was lost. I think it was a regular self-storage space.

That aside, this sounds extremely old-fashioned, but it seems to me that the only media that is acceptable for long-term storage is going to be punched paper tape. How long does paper last? How long do the holes in it remain readable? Can it be spliced and repaired?
