I've been asked to provide a DR/BAckup solution that seems to
contradict TSM methodology, but I've decided I'll throw this in here
anyway.

Given the following retention policy:
RETE=180
RETO=180
VERE=NOL
VERD=NOL
(180 days, no version limit)

I've been asked to find a way to keep offsite only 7 days worth of
data (on deduped disk or somthng like that), both active and inactive.
So that it would allow us to restore complete system image from any
day within last week.

Doable (without resorting to double backups under different MCs)?
