Re: [ADSM-L] Percent Total Space Saved calculation

Hello Robert,
We are on 7.1.4, so can't be 100% sure, but for what I see from your mail:
Total Space Saved is Deduplication Savings (163G) plus Compression Savings
(339G) = 502G
Space used is 10240G * 3.5% = 358.4G
So a sum of occupancy should be 502+358 = 860G
58.26% of 860G = 501G..... close enough ;-)
Regards,
Maurice van 't Loo
