Because I wanted to let Duplicati run on an ARM computer (in my case odroid XU4), and all my services are already Docker containers, I built a Docker Image for Duplicati that works on the arm32v7 plattform.
It can be just pulled from dockerhub, or built from git source. I also added examples for docker-compose:
https://hub.docker.com/r/psywolf/docker-duplicati-arm32v7/
I hope its useful for some of you that appreciate not to start from zero.
Contributions to the Git Repo or Forks are more than welcome.

Welcome to the forum @psywolf85, and thanks for the awesome contribution!
Hi,
I’m using your docker image on a cubietruck. I was hoping to be able to backup all the files of the cubietrack via Duplicati to a local NAS.
Duplicati seems to work. But when selecting source files it seems to miss some sub directories. Ie. /opt is shown but not its subdirectories.
Any ideas what could cause this?
Kind regards and thank you for you work.
Hi,
A Docker container is isolated from the rest of the system. You have to make a folder available to it.
How to you start your docker image?
With this command the folder /data of the host system is mounted in to the container at /data
docker run -it -d -v /data:/data -v /data/duplicati:/root/.config/Duplicati -p 8200:8200
And the folder /root/.config that includes the config of Duplicati inside the container is made available to my Host system to make it persistent. Also that folder can be backuped 
If you have any question, let me know

Thank you for the hint. Indeed I just stupidly copy&pasted your example parameters when starting the docker container.
Now I switched to
docker run -it -d -v /:/data -v /data/duplicati:/root/.config/Duplicati -p 8200:8200 psywolf/docker-duplicati-arm32v7
Now dupliciati tells me it’s going to backup 100GB from a 10GB filled disk. But that’s another story
Thank you very much for your quick support and merry christmas to you and your family!
