UrBackup Docker Client

Source files for the Docker image hejare/urbackup-client at https://hub.docker.com/r/hejare/urbackup-client/.

Introduction

The UrBackup solution has a comprehensive list of featuers and supported systems. The official website states that

UrBackup is an easy to setup Open Source client/server backup system, that through a combination of image and file backups accomplishes both data safety and a fast restoration time.

This Docker image runs a UrBackup client. Note that it does not run the UrBackup server. Please see https://www.urbackup.org for more information on the complete UrBackup solution.

Starting the Docker container

You may start the container by running

docker run \
  -p 35621:35621 -p 35622:35622 -p 35623:35623 \
  -v /path/on/host:/backup/name:ro \
  hejare/urbackup-client

This will start the UrBackup client and automatically connect to any UrBackup servers on the local network. The necessary ports are forwarded from the Docker container. By default, the container will backup files found in /backup and all its sub directories. Mounting a host directory to that path enables the client to backup the files. Note the :ro parameter making the mount read-only for the container.

In order to connect the client to a server outside of the local network, a number of additional parameters as environment variables are needed:

docker run \
  -p 35621:35621 -p 35622:35622 -p 35623:35623 \
  -v /path/on/host:/backup/name:ro \
  -e COMPUTERNAME=<your-client-computer-name> \
  -e INTERNET_MODE_ENABLED=true \
  -e INTERNET_SERVER=<your-server-name-or-ip> \
  -e INTERNET_AUTHKEY=<your-client-authkey> \
  hejare/urbackup-client

There is also an optional parameter INTERNET_SERVER_PORT that defaults to 55415.
