I  believe the key to long term storage is the notion of data refreshment on
the tapes.  With reclamation, we get that.  If archive data is mixed with
backup data we get reclamation due to backup retention policies being much
less (typically) than archive.  Some will argue that moving this data around
isn't efficient, but if ensuring that data can be read is the goal, moving
it around occasionally is important.
