How to use this image

$ docker run -p 8200:8200 -v /some/path:/some/path duplicati/duplicati

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.

Preserving configuration

All configuration is stored in /data inside the container, so you can mount a volume at that path to preserve the configuration:

$ docker run --name=duplicati -v duplicati-data:/data duplicati/duplicati

This allows you to delete and recreate the container without losing your configuration:

$ docker rm duplicati
$ docker run --name=duplicati -v duplicati-data:/data duplicati/duplicati

Using Duplicati CLI

Run the duplicati-cli command to use the Duplicati command-line interface:

$ docker run --rm duplicati/duplicati duplicati-cli help
See duplicati.commandline.exe help <topic> for more information.
