I did not get any new information when looking in /var/log/syslog. There are no
errors. But I solved the problem by using rsync instead of rsyncd as XferMethod
with the following rsync arguments: --timeout=604800 --contimeout=604800
--no-compress
I only had to exchange some public keys within the same machine.

I use the "--no-compress" parameter because of this bug:
https://bugzilla.samba.org/show_bug.cgi?id=7757
I do not really know if that bug stll exists in rsync version 3.1.1 but I wanted
to be sure.

The internal backup path now looks a bit different:
/var/lib/backuppc/pc/<computer>/<mount>
Before <mount> was the name of the rsync share. Now it is the absolute path
which has to be backed up. The backup runs smoothly now and I can see the actual
command line with 'ps aux', 'htop' and similar tools. All parameters listed in
RsyncArgs and RsyncArgsExtra were used.
