Imagine the costs of not having the data for planes still being flown. Missing manuals, tech specs, testing procedures, etc. for some strange part that was manufactured 40 years ago, with completely different people, tooling and processes. I believe the cost of missing data is much larger than keeping an archival storage, we have been doing archiving for a long, long time as a species.
