Re: Backups are performed but are empty

I can now rule out that we were hacked or caught a virus.
As is so often the case, the problem was sitting right in front of the 
monitor and keyboard: me. :-(
I was able to trace it using the backups from the backuppc server. By 
default, /etc is backed up.
We use a Univention Corporate Server as a domain controller with a Samba 
server for the AD domain.
When the change to config.pl took place, I tried to configure backuppc 
to back up /etc of the domain controller.
It is not possible to change the ssh port on the domain controller, as 
otherwise the Linux domain would not function properly.
Since it was not possible to back up the domain controller using either 
tar or rsync, I had the "brilliant" idea of trying rsyncd.
In doing so, I accidentally saved the change in config.pl instead of 
saving it in the domain controller's config files.
Before the change, config.pl contained $Conf{XferMethod}=rsync and 
$Conf{RsyncClientPath}= "c:\\Program Files\\OpenSSH\\vss.exe".
Afterwards, $Conf{XferMethod}=rsyncd and 
$Conf{RsyncClientPath}=/usr/bin/rsync. Of course, /usr/bin/rsync does 
not exist on Windows clients.
Small change, big impact.
Thanks again for your help. Without you, I would probably still be 
searching.

Greetings

Jörg
