I don't exactly follow you.   In the case of a specific example for NASA
and its vendors a given mission may involve tens of thousands of tapes.
When a mission concludes, tapes are usually bundled off to a warehouse
and then later junked.   There's no money in the mission budget for
preservation ad perpetuum.
