How to setup Duplicati (with Docker)

Ready to use

Description

Duplicati is a free, open-source backup client that securely stores encrypted, incremental, and compressed backups on cloud storage services and remote file servers

Folders

Create the folder structure.

cd ~/services
mkdir -p duplicati/{config,data}

Docker

Add the duplicati section to your docker-compose.yml file:

  duplicati:
    image: duplicati/duplicati
    container_name: duplicati
    ports:
      - "8200:8200"  # Web UI
    environment:
      - DUPLICATI__WEBSERVICE_PASSWORD=password # replace this with a strong password (see below)
      - SETTINGS_ENCRYPTION_KEY=password # replace this with a strong password (see below)
    volumes:
      - /home/dan/Downloads/bkp_test/sources:/source # replace this with the path to the sources you want to backup
      - /home/dan/Downloads/bkp_test/dests:/backup #replace this with the path to the location where you want to store your backups
      - ./duplicati/config:/config
      - ./duplicati/data:/data # this is important! without this, your backup jobs will be gone after a docker compose down
    restart: unless-stopped

You can generate strong passwords with:

openssl rand -hex 24

Download and start duplicati:
```
docker compose up -d duplicati
```
Try it out

See if you can access http://your_server_IP:8200.
