Barman is a lightweight and efficient database backup and recovery manager for PostgreSQL databases. It provides various features including the capability to perform remote or local backups, incremental backups, backup catalogues, and recovery throughout time. In this tutorial, we will guide you on how to install Barman on Windows 10.
Before installing Barman, make sure that you have the following prerequisites:
To install Barman, open your command prompt by pressing Windows+R and typing cmd in the Run dialog box. Once the command prompt is open, type the following command:
pip install python-barman
This command will download and install the latest version of Barman and its dependencies.
Once you have installed Barman, you need to configure it to work with your PostgreSQL database. To do this, open your text editor and create a new file called barman.conf in your C:\Program Files\Barman directory.
[C:\\Program Files\\Barman\\barman.conf]
[barman]
barman_home = C:\\Program Files\\Barman
log_file = C:\\Program Files\\Barman\\barman.log
log_level = INFO
barman_user = barman
barman_group = barman
In this configuration file, you need to specify the location of your Barman installation, the location of the log file, and the username and group name for Barman.
After configuring Barman, you need to modify the postgresql.conf file in your PostgreSQL installation directory to allow Barman to connect to your PostgreSQL database. To do this, open the postgresql.conf file in your text editor and add the following lines:
wal_level = archive
archive_mode = on
archive_command = 'barman-wal-archive barman postgres %p'
Now, save the file and restart the PostgreSQL service.
After configuring PostgreSQL, you need to configure your backup. To do this, create a new file called backup.conf in your C:\Program Files\Barman directory.
[C:\\Program Files\\Barman\\backup.conf]
[postgresql]
conninfo = host=<HOSTNAME> dbname=<DBNAME> user=<USER> password=<PASSWORD>
[barman]
backup_method = postgres
In this configuration file, you need to specify the connection information for your PostgreSQL database.
After configuring your backup, run the following command to perform your first backup:
barman backup postgres
This command will create a backup of your PostgreSQL database and store it in the Barman backup system.
With these steps, you have successfully installed and configured Barman on your Windows 10 computer. You can now use Barman to create backups and restore your PostgreSQL databases with ease.
