How much data are your guys S3's using in a month with the current block settings ?

I have a something on my network thats using 5GB a day now, and its just a PC and two miners, and the PC isnt the culprit i checked already but not sure how much data the miners are using but it shouldnt be that high, it used to be a couple hundred MB.

Not sure if the stats in the antminer log the total data statistics, seems to only show realtime.
