Barman is a tool used to backup and recover PostgreSQL. It is used to manage backups of PostgreSQL servers, including continuous archiving and point in time recovery.
In this tutorial, you will learn how to install Barman on MXLinux Latest.
Before we can install Barman, we need to install PostgreSQL on our MXLinux machine.
To do this, open a terminal and run the following command:
sudo apt update
sudo apt install postgresql-13 postgresql-contrib-13
The Barman package is not available in the default repositories, so we need to add an external repository that has the package.
To add the repository, run the following command:
sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ bullseye-pgdg main' >> /etc/apt/sources.list.d/pgdg.list"
Next, we need to import the repository signing key:
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
Now that we have added the repository, update the package list:
sudo apt update
Finally, we can install Barman:
sudo apt install barman
After installation, we need to configure Barman by creating a configuration file.
sudo nano /etc/barman.conf
In the configuration file, we need to specify the PostgreSQL server we want to back up.
Add the following to the configuration file:
[pgserver]
description = PostgreSQL Server
conninfo = host=127.0.0.1 user=postgres password=<password> dbname=postgres
backup_method = rsync
streaming_archiver = on
In the conninfo line, replace <password> with the password for the PostgreSQL server.
Save and close the configuration file.
We can now test Barman by running the following command:
barman check pgserver
This command will check that Barman can connect to the PostgreSQL server and that all necessary components are installed correctly.
If the test is successful, we can now run the following command to backup the PostgreSQL server:
barman backup pgserver
Congratulations! You have successfully installed and configured Barman on your MXLinux Latest machine. With Barman, you can now easily backup and recover your PostgreSQL server.
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!
