There are companies (Iron Mountain comes to mind) that have *large*,
secure, temperature-controlled warehouses (an old mine, in Iron
Mountain's case) and couriers that will bring your tapes (and
other documents, for that matter) to their facilities.

You put the "stuff" to be brought off-site in a special box, with
the "recycle date" on it.  Each day/week/month, they will bring
back the "old" box(es) and take away the "new" box(es).

For a fee, or as part of the service contract, some will even
bring out boxes at odd hours of the night/weekend.
