I wonder if there is a good way to estimate the effect of changing the setting "Number of days to dedupe against". I'd like to estimate the new usage on disk.
The base is.
Current retention is 35 days 1 cycle with weekly fulls. Dedupe against days is unchanged (365 days).
We looking into do 365 days 1 cycle and change the dedupe against days to 180.
I thought if it coulde be as simple as do the following.
Average of all incrementals times (365-52)*2
Avarage of all Full times 52
Plus baseline * 2
Will that give me an estimate that is kind of accurate.
Anyone done something similar?
