How to Install Elkarbackup on Fedora CoreOS

In this tutorial, we will guide you through the installation process of Elkarbackup on the latest version of Fedora CoreOS. Elkarbackup is an open-source, cloud-based backup solution designed to manage backups over a network of clients.

Before beginning the installation process, ensure that you have:

• A server or a virtual machine running Fedora CoreOS latest version
• Superuser access to your system

Step 1 - Install necessary prerequisites

To install Elkarbackup on your Fedora CoreOS system, you will need to install the necessary packages:

sudo dnf install docker git

Once the installation completes, you can start the Docker service:

sudo systemctl start docker
sudo systemctl enable docker

Step 2 - Clone the Elkarbackup repository

Clone the Elkarbackup Git repository into a directory on your system. In this example, we will clone it inside the /opt directory:

sudo git clone https://github.com/elkarbackup/elkarbackup.git /opt/elkarbackup

Step 3 - Configure the Elkarbackup engine

The Elkarbackup engine is the core part of the backup software. It is responsible for managing backups, including schedules, retention policies, and more. To configure the engine, you need to create an elkarbackup.yml file in the /opt/elkarbackup directory:

sudo vim /opt/elkarbackup/elkarbackup.yml

Add or edit the following options:

path: "/root/backups"
storage:
  type: local
volumes: 
  - /var/lib/docker

• path: The directory where backups will be stored
• storage: The type of storage backend to use (e.g., local, NFS, SSH)
• volumes: The directories or files to back up

In this example, we are backing up the Docker data directory.

Step 4 - Build and start the Elkarbackup Docker images

The next step is to build and run the Docker images:

cd /opt/elkarbackup
sudo docker-compose up -d

This command will build and start the Elkarbackup Docker images in the background.

Step 5 - Access the Elkarbackup Web UI

Once the Docker images are up and running, you can access the Elkarbackup Web UI.

Open a web browser and navigate to http://:8080. The Elkarbackup login page should appear.

Log in with the default credentials:

• Username: admin
• Password: elkarbackup

You will be redirected to the Elkarbackup dashboard, where you can manage and configure your backups.

Conclusion

Congratulations! You have successfully installed Elkarbackup on your Fedora CoreOS system. You can now start creating backups on your networked clients and accessing them via the Elkarbackup Web UI.
