Barman is a backup and recovery manager for PostgreSQL databases. It is designed to manage PostgreSQL backup and recovery tasks for multiple servers, and can perform incremental backups to help reduce storage requirements.
In this tutorial, we will walk you step-by-step through the installation process of Barman on OpenSUSE Latest.
Before you start, ensure that you have:
Firstly, you need to add the Barman repository to your OpenSUSE Latest system. To do that, use the following commands:
sudo zypper ar https://download.opensuse.org/repositories/server:/database:/postgresql/openSUSE_Latest/server:database:postgresql.repo
sudo zypper ref
Once you have added the repository, you can install Barman by using the following command:
sudo zypper in barman
After installation, you need to configure Barman with PostgreSQL settings. To do that, start by creating the Barman configuration file:
sudo mkdir /etc/barman.d/
sudo touch /etc/barman.d/pg_server.conf
sudo chown -R barman:barman /etc/barman.d/
Then, in the newly created configuration file /etc/barman.d/pg_server.conf, paste the following contents:
[pg_server]
description = PostgreSQL Server
conninfo = host=<postgreSQL_IP> port=<postgreSQL_port> user=<backup_user> dbname=postgres
backup_method = postgres
streaming_archiver = off
streaming_backup_name = barman_backup_streaming
streaming_conninfo = host=<postgreSQL_IP> port=<postgreSQL_port> user=<barman_user>
In the above configuration:
<postgreSQL_IP> and <postgreSQL_port> with the IP address and port number of your PostgreSQL server.<backup_user> with the name of your PostgreSQL backup user.<barman_user> with the name of the Barman user.To integrate Barman with PostgreSQL, you need to create a backup user and grant it the necessary permissions. To do that, open the PostgreSQL shell:
sudo su postgres
psql
Then, create the backup user:
CREATE USER <backup_user> WITH PASSWORD '<backup_password>';
Next, create the streaming replication user:
CREATE USER <barman_user>;
Finally, grant the necessary permissions to the backup and replication users:
ALTER USER <backup_user> WITH SUPERUSER;
GRANT REPLICATION TO <barman_user>;
Exit the PostgreSQL shell by typing \q.
After configuration, you can start Barman by using the following command:
sudo systemctl start barman
That’s it! You have successfully installed Barman on OpenSUSE Latest and configured it to work with your PostgreSQL database. Now, you can use it to manage your PostgreSQL backup and recovery tasks effortlessly.
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!
