sadly the error appeared this night and the logfiles don't give any more information I think. In one session I get a part that is succeeded and the next part failed:
Got fatal error during xfer (Unable to read 4 bytes)
Backup aborted (Unable to read 4 bytes)
And it did try it all night:

Hopefully someone has an idea how to debug this further.

It's weird there is nothing added in the log, usually rsync -vv tells you everything you might wanna know... maybe backup pc filters the output.
did you check the normal xfer log (not xfer errors)? it's more talkative.
