This is how I got a backup from a QNAP nas to Zentyal working (I understand that most people probably want to do this the other way around…)

QNAP TS-231 running 4.1.3 Build 20150408
Zentyal 3.5

1. Setting up rsync on Zentyal: http://howden.net.au/thowden/2012/11/rsync-on-debian/
2. Testing rsync on QNAP:
   1. Open up ‘Backup Station’ App
   2. Go to ‘Rsync’ under ‘Remote Replication
   3. Create a new replication job, use the following settings:
   • Remote Replication Job Name:
   • Remote site:
     Name or IP: [IP address of Zentyal box].
     Username: [Zentyal Admin User]
     Password: [Zentyal Admin Pass]

     Port Number: 873

   Hopefully the test should run successfully, if you cat /var/log/rsyncd you should see the connection, but it probably fails on finding /var/www/pub folder

   4. If everything works, go ahead and update the configuration files, and set locations to their final paths

   I can’t work out how to get this working over SSH just yet.
