Urm, ok. This is not what I expected to see from the message subject
This really depends on what archiving strategy you would want to employ, i.e. archiving items 1 month old, 3 months old, 6 months old, etc etc.
It is a very hard thing to say "oh you will archive X in Y months" without knowing your average throughput and ultimately what you want to achieve.
You could archive everything that comes in, using a 0 day policy.
I would advise speaking with a re-seller or our Professional Services arm and take it from there. At the end of the day, EV will archive what you configure it to.
