Dude v6 - Database disk sizing

Hello
I am testing CHR on a QNAP nas, i wanted to activate thedude so i 'd like to know how much size should i provide for the DB. Is there some formula i should use to size the secondary disk to contain the dude database? Client network is a single /24 and I’d like to keep at least 3 months of data(no more than 12 months). Up to three switches(core+maybe two haps if i can get some decent performance metrics), one router.

Few megabytes. No more than 20MB in case of standard aggregation settings.

Oh ok, I’ve provisioned 60G to be sure so I won’t be hitting the size limit for quite a while. Thank you!

Definitely an overkill…
