+# Backup in Linux Servers - Docker Volumes, and Databases
+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.

+## Prerequisites
+
+- 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!
+
+## 1. Install Docker, and Docker-Compose
+
+You can still install Docker on a Linux Server that is not running Ubuntu, however, this may require different commands!
+
+### 1.1. Install Docker
+```bash
+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 $(lsb_release -cs) stable"
+
+sudo apt update
+
+sudo apt-get install docker-ce docker-ce-cli containerd.io
+```
+
+### 1.2. Check if Docker is installed correctly
+```bash
+sudo docker run hello-world
+```
+
+### 1.3. Install Docker-Compose
+
+Download the latest version (in this case it is 1.25.5, this may change whenever you read this tutorial!)
+
+```bash
+sudo curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
+
+sudo chmod +x /usr/local/bin/docker-compose
+```
+
+### 1.4. Check if Docker-Compose is installed correctly
+```bash
+sudo docker-compose --version
+```
+
+### 1.5. (optional) Add your linux user to the `docker` group
+```bash
+sudo usermod -aG docker $USER
+```
+
+## 2. Set up Duplicati
+
+### 2.1. Create a Docker-Compose file
+
+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.*
+
+### 2.2. Start Duplicati
+
+Navigate to your project folder, and execute the following command.
+
+```bash
+docker-compose up -d
+```
+
+### 2.3. Configure Duplicati
+
+Open the web interface of **Duplicati** at `http://your-server-address:8200`, and log in with the default username, and password `...` / `...`.
