Backup in Linux doesn't need to be complicated. I'll show you backup strategies and tools to create a reliable backup for your entire Linux server. You can use this perfectly in combination with Docker Volumes and Databases.

We will use the free and open-source software Duplicati.

• Linux Server running Ubuntu 20.04 LTS or newer
• Domain that points to the public IP of your Linux Server

You can still install Docker on a Linux Server that is not running Ubuntu, however, this may require different commands!

sudo apt update

sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

sudo apt update

sudo apt-get install docker-ce docker-ce-cli containerd.io

sudo docker run hello-world

Download the latest version (in this case it is 1.25.5, this may change whenever you read this tutorial!)

sudo curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

sudo docker-compose --version

sudo usermod -aG docker $USER

Create a new docker-compose.yml file in your project folder e.g. /home/<your-username>/nextcloud.

You can also create a new folder in the /opt directory, this may require different permissions.

Navigate to your project folder, and execute the following command.

docker-compose up -d

Open the web interface of Duplicati at https://your-server-address:8200, and log in with the default username, and password ... / ....
