How to Install UrBackup Server and Client on Ubuntu 20.04

Regularly backup the live server is a very important task of any system administrator. It will help you to recover your data in the event of data loss or system failure. There are a lot of free and commercial backup tools available in the market.

UrBackup is an open-source and client/server backup system for Linux operating systems. It supports both file and image backups in a live system without interrupting current processes. It provides a web-based interface to manage all backups. It is cross-platform and can be installed on Windows, FreeBSD, Linux, and many Linux-based NAS operating systems.


UrBackup offers a rich set of features, some of them are listed below:

  • Free and open-source
  • Multi-platform
  • Space efficient
  • Easy to setup
  • Consistent backups while in use
  • Backup via Internet


  • Two servers running Ubuntu 20.04.
  • A root password is configured on both servers.

In this tutorial, I will show you how to install the UrBackup server and Client on Ubuntu 20.04.

Update the System

Before starting, it is recommended to update all system packages on both server and client machines.

Run the following command to perform the update:

apt-get update -y

Once all the packages are updated, install other required dependencies using the following command:

apt-get install curl gnupg2 software-properties-common -y

After installing all the dependencies, you can proceed to the next step.

Install UrBackup Server

By default, UrBackup is not available in the Ubuntu default repository. So you will need to add UrBackup repository to your system.

You can add the UrBackup repository with the following command:

add-apt-repository ppa:uroni/urbackup

Once the repository is updated, install the UrBackup server with the following command:

apt-get install urbackup-server -y

During the installation, you will be asked to provide the backup location as shown below:

Configuring urBackup server

Provide your backup location and click on the Ok button to finish the installation.

Next, start the UrBackup service and enable it to start at system reboot:

systemctl start urbackupsrv
systemctl enable urbackupsrv

Next, verify the status of the UrBackup service with the following command:

systemctl status urbackupsrv

You should see the following output:

? urbackupsrv.service - LSB: Server for doing backups
     Loaded: loaded (/etc/init.d/urbackupsrv; generated)

By default, UrBackup listens on ports 55413 and 55414. You can check them with the following command:

ss -antpl | grep urbackupsrv

You should see the following output:

LISTEN    0         4096       *        users:(("urbackupsrv",pid=7081,fd=27))                                         
LISTEN    0         4096       *        users:(("urbackupsrv",pid=7081,fd=6))

LISTEN    0         4096                  [::]:55414               [::]:*        users:(("urbackupsrv",pid=7081,fd=7)) 

Next, set proper ownership to the /mnt directory with the following command:

chown -R urbackupsrv:urbackupsrv /mnt
