Time Machine : Volume size limit ignored

Hello all,

 

I use Unraid 6.9.1.

On a 4Tb drive, i setup a Time Machine share for my mac :

 

Then, i configured the Share as follow :

 

In Krusader, my TimeMachine folder excess the 2Tb limit :

 

On my mac, i have another values, but still above 2Tb :

Notice also that macOS reported 2.1 To available instead of 400Go as reported by Unraid.

 

Does the TimeMachine limit isn't respected ?

Did i miss something, like between Tb and Tib and maybe To ?

 

I know that for years, when you bought a 4Tb drive, you only usually get 3.6Tb of space.

I understand that recently, macOS shows a 4Tb drive as a "real 4Tb" drive, and consequently, report larger file than in Windows to compensate.

 

Is that the same case here ? Did i miss something ?

 

Thank you !
