There could be some serious issues with this.  If you have an onsite
volume that has 170 day old data, with 5 day old data and 80 day old
data (due to reclamation), and the volume goes bad, all you'll be able
to restore is the 5 day old data.

However, this is a real challenge.  I'd like to see the solution.

It appears on the surface that this is a result of is the "we want to
keep it forever but can't afford the cost" mentality.  Champagne taste
on Beer budget.
