Thanks, I will look into this.

When backing up Docker volumes, should not the docker container be stopped first.?? I can’t se any support for that in the backup tools mentioned.

You are correct. ( Idiots should not play around with Docker)

Yeah, I followed them and have Openproject more or less up and running. ( cant change port although)

Still, all other of my services are managed by Portainer and I would like to have Openproject into that echo system.
