Our "indefinite" backups have a Networker retention time of a decade
(10 years.)  As it was mentioned, the retention policy just defines when
Networker can mark the tape as recyclable.  Since the media is out of
the jukebox, and write-protected, I don't worry about those tapes
getting invalidated as far as Networker is concerned.  I will be a
little concerned if I am actively using LTO-3 media in 10 years.
