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.
