Can you give us your actual torrc lines?

Also, how about the log lines, particularly the ones that talk about
when it woke up, when it went into hibernation, when it plans to wake
up again, etc?

Maybe some of these transmitted bytes went to other Hetzner servers,
which they don't count as "really" sending bytes to the Internet.

> Because if Hetzner???s stats are correct i would have send 3 TB???s of Traffic to other Tor servers and clients internally. Because internal traffic is not counted.

Ah, yes, this is what you suggested. Maybe? That's a lot (a large
fraction) given that Hetzner doesn't have that large a fraction of the
Tor network these days.

Tor said you sent 38TB, so that's 38TB of outgoing traffic.

Maybe your 27 days contained two hibernation periods? That would be
one possible explanation for 19+19=38.
