Hello fellow calculators

I am doing a sizing for a customer who wants to keep 12 monthlies and 5 yearlies in VDC with immutability for as long as technically reasonnable. 
I have in mind that, as long as we are not in a SOBR, in v13 I can select “ For the entire duration of their retention policy” but I am not sure of the impact on the storage consumption.
In the calculator it doesn’t seem possible to go beyond 90 days immutability (or I may have missed it).
How can I estimate the immutability impact on storage ?
Thx

    hi ​@PYB 
    Under the Veeam Vault Calculator enable the advance slider (highlighted0 Calculator - VDC Vault 

    this will give you the GFS setting your looking for. 

    I’ve mocked up what it work look like inside a Calculator based on my understand of your post. 
    There a few extra parameters when you enable to advanced mode.

      Hello Jason, thanks for taking the time.

      This is what I did already, I guess my question boils down to “how much additionnal space do I consume if I set my immutability to cover the full retention period” (in my context 5 years)

      As far as I’ve seen, 90 days seems to be the maximum amout you can input in the calculator.
      But this is an unusual calculation since it would be for externalizing monthlies/yearlies (no dailies) with a backup copy job from  StoreOnce repo, so quite a specific use case
