[Guide] ICH777 OpenVPN client + Synology hyperBackup + rsync daemon

[Croontje]

I have been looking for a way to have a Synology backup to my unraid with hyperbackup over a VPN. And finally I found a good solution.
I want to document it here. I hope this is usefull for someone. If you can spot issues/problems please let me know

 

Why no wireguard? As far as I know, this is not possible on my synology.
 

1. Install VPN package on synology and enable the OpenVPN
   See Step_1.PNG
2. Export the OpenVPN configuration, replace remote YOUR_SERVER_IP with your server IP/DYNDNS in the VPNConfig.ovpn file
3. Configure the ICH777 OpenVPN client following the instructions (do I need to elaborate more on this?)
   The basic steps for a OpenVPN connection that requires a Username and Password are: 1) Rename your *.ovpn to 'vpn.ovpn' and place it in your OpenVPN-Client directory, 2) Create in the same directory a file named 'vpn.auth' and place your Username in the first line and the Password for the connection in the second line and save it 3) Restart the container open the logs and see if the connection to your VPN establishes successfully.
4. Add 2 extra paths to this Unraid docker: See Step_4.PNG
5. Create the install_rsync.sh file and place it in the correct path with following contents: (linux linefeeds!)
   Restart your OpenVPN client container after this. VPN connection should be established and "ps aux" should show rsync daemon installed and running.

   apt-get update
   apt-get -y install rsync
   
   cat <<EOT > /etc/rsyncd.conf
   uid             = root
   gid             = root
   use chroot      = no
   max connections = 4
   pid file        = /var/run/rsyncd.pid
   log file        = /hyperBackup/rsyncd.log
   timeout         = 600
   reverse lookup = no
   
   [hyperSYN]
      path = /hyperBackup
      comment = /hyperBackup
      read only = FALSE
   EOT
   
   rsync --daemon

    

6. Go to Diskstation and create Hyperbackup databackup task: (see Step_6.PNG)

• First screen: destination type: rsync
• Second screen, use options in screenshot:
      IP is the IP your docker gets from the OpenVPN server
      Username and password doesn't matter
      Backup module is the one in square brackets from the install_rsync file
      Directory is the HBK folder that will hold your backup (will be autocreated)
• The options in the following screens you can choose as you wish

 

Normally this should work ...

Don't know if it would be better to create a new docker. Thanx @ich777 for the OpenVPN client docker
