Installing Barman

First, we need to add the PostgreSQL apt repository to the system by running the following command:

Import the PostgreSQL signing key:

Update the system package list:
```
$ sudo apt update
```
Install Barman on your system using the following command:

```
Once the installation is done, configure Barman using the following command:
```
$ sudo vi /etc/barman.conf
```
You can modify the default configuration settings based on your setup. Some important settings to consider are:
- barman_user: Sets the user account under which Barman will operate. Make sure the value of this field is an existing user account on your PostgreSQL server.
- pg_basebackup: This setting controls how Barman connects to your PostgreSQL server to take a backup. Make sure the values of this field match the settings in your pg_hba.conf configuration file.
After saving the configuration file, restart the Barman service using the following command:
