Server Backups with Duplicati

Duplicati is an easy way to back up any of your servers and even Desktops.

I’ll be using the linuxserver version of duplicati.

Linuxserver is a cool collection of community maintained images.

Read more on DockerHub, GitHub, Linuxserver.

1. Setting it up

You need Traefik set up!

Create a new subdomain and point it to your server.

Alright, as always we’ll need to create a new directory and cd into it.

mkdir duplicati && cd duplicati

Then create a docker-compose.yml

nano docker-compose.yml

Remember to replace your-domain.com with your domain and replace the Timezone (TZ) as well.

version: "2.1"
services:
  duplicati:
    image: ghcr.io/linuxserver/duplicati
    container_name: duplicati
    environment:
      - PUID=0
      - PGID=0
      - TZ=Europe/Berlin
    volumes:
      - ./config:/config
      - /home/duplicati_backups:/backups
      - ./source:/source
    networks:
      - web
    restart: always
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.duplicati-web.rule=Host(`duplicati.your-domain.com`)"
      - "traefik.http.routers.duplicati-web.entrypoints=web"
      - "traefik.http.routers.duplicati-web.middlewares=bitwarden-https-redirect"
      - "traefik.http.routers.duplicati-web.middlewares=redirect@file"
      - "traefik.http.routers.duplicati-secured.rule=Host(`duplicati.your-domain.com`)"
      - "traefik.http.routers.duplicati-secured.tls=true"
      - "traefik.http.routers.duplicati-secured.tls.certresolver=web"
      - "traefik.http.routers.duplicati-secured.entrypoints=web-secured"
      - "traefik.http.routers.duplicati-secured.tls.certresolver=mytlschallenge"

networks:
  web:
    external: true

2. How to Use

Now visit the domain you provided (duplicati.your-domain.com) or the IP you provided.

Your Home should look something like this.

At first, we’ll set up a password, by going to Settings and confirming our password.

Next, configure a new backup, by going to add Backup.

Now go through the steps.

Name is the name of your Backup. Passphrase is the password it’ll ask for to access the Backup, if you want to restore it.

Choose your Destination folder, to access root folders, you’ll need to give the username root and the password.

The Source Data is the folders you want to save as a Backup.

You can schedule your Backups. When should they run? How often a day/week/month?

In the Options, you can specify some things. For example, how many Backups to keep. I like to keep 10.

Then click Save and we’re done.
