Barman is an open-source tool for managing PostgreSQL backups, which can be used to simplify backup and recovery processes. Here's how to install Barman on the latest version of Elementary OS:
Before you begin installing Barman, you need to ensure that your system meets the following prerequisites:
First, you need to install the necessary packages and dependencies. Open the terminal and run the following command:
sudo apt-get install -y python-pip python-dev libpq-dev sshpass
This will install the required packages for Python, Postgres, and SSH support.
Once you have installed the dependencies, you can install Barman using the following command:
sudo pip install pgbarman
This command will download and install Barman on your system.
After the installation is complete, you can verify the installation by running the following command:
barman --version
This command will display the version of Barman that you have installed.
Before you can start using Barman, you need to configure it. You can do this by creating a barman.conf file in the /etc/barman.d/ directory. You can use the following command to create the file and edit it:
sudo nano /etc/barman.d/barman.conf
In this file, you need to add the following details:
[barman]
barman_user = <barman_username>
barman_password = <barman_password>
backup_directory = /var/lib/barman/%(server_name)s
Replace <barman_username> and <barman_password> with the username and password you want to use for Barman. Also, ensure that the backup_directory is set to the proper path.
Save the file and exit the editor.
To enable Barman to connect to the PostgreSQL server, you need to configure SSH. You can do this by adding the following details to the /etc/barman.d/pg.conf file:
[streaming]
enabled = 1
method = ssh
ssh_command = ssh postgres@<postgres_server_ip> -p 22
rsync_options = -p --chmod=go-w
streaming_conninfo = host=<postgres_server_ip> user=barman dbname=postgres
Replace <postgres_server_ip> with the IP address of your PostgreSQL server.
Save the file and exit the editor.
To start using Barman, you can run the following command:
sudo systemctl start barman
This will start the Barman service.
That's it! You have now installed and configured Barman on your Elementary OS system. You can now use Barman to manage your PostgreSQL backups.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
