How to install Duplicati on Synology / DSM

How-To
76

I now have Duplicati running in Docker on my Synology. I can open the Duplicati GUI.
I’m using this opportunity to learn something more about Docker, and then read this:

Then, open http://localhost:8200 on the host to access the Duplicati web interface and configure backups. Any host directory that you want to back up needs to be mounted into the container using the -v option.

Now I see there is a terminal page in the Duplicati Docker window in DSM, but I am unsure on how to proceed. I know how to mount a drive in a regular Linux install. But I get the feeling this is not quite the same, and am unable to find what I’m looking for when Googling.

Do you have any experience in this you can share?

Thanks.
