Barman is a backup and recovery tool for PostgreSQL servers. In this tutorial, we will show you how to install Barman on Debian latest.
Before we begin with the installation, make sure that you have the following:
If you don't have PostgreSQL installed on your system, you can do it by running the following command:
sudo apt-get update
sudo apt-get install postgresql postgresql-client
Barman is available in the official Debian package repository. To install it, run the following command:
sudo apt-get update
sudo apt-get install barman
After the installation, you need to configure Barman by editing the configuration file. The configuration file is located at /etc/barman.conf.
Open the configuration file using your favorite editor and configure the following settings:
[barman]
barman_user = barman
barman_group = barman
backup_directory = /var/lib/barman
log_file = /var/log/barman/barman.log
[postgresql]
conninfo = host=<postgresql server address> user=barman dbname=postgres
backup_method = postgres
streaming_archiver = on
Replace <postgresql server address> with the IP address or hostname of your PostgreSQL server.
Barman needs a PostgreSQL user to connect to the PostgreSQL server. You can create a new user by logging in to the PostgreSQL server using psql and running the following command:
CREATE USER barman WITH SUPERUSER LOGIN PASSWORD 'password';
Replace password with a strong password.
Now that you have installed and configured Barman, you can test it by running a backup.
To take a backup, run the following command:
sudo -u barman barman backup <postgresql server name>
Replace <postgresql server name> with the name of your PostgreSQL server.
After the backup completes, you can check the status of the backup by running the following command:
sudo -u barman barman list-backup <postgresql server name>
In this tutorial, you learned how to install and configure Barman on Debian latest. With Barman, you can easily backup and recover your PostgreSQL databases.
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!
