Installing#

Barman official packages are provided by PGDG. These packages use the default version of Python 3 that comes with the operating system.

There are three packages that make up the suite of Barman features: barman, barman-cli and barman-cli-cloud.

  • barman is the main package and it must be installed.

  • barman-cli is an optional package that holds the barman-wal-restore and barman-wal-archive utilites. This package is mandatory if you plan to use those utilities as the archive_command or restore_command. It must be installed on each Postgres server that is part of the Barman cluster.

  • barman-cli-cloud is an optional package that holds the barman-cloud-* client scripts that you can use to manage backups in a cloud provider. It must be installed on the Postgres servers that you want to back up directly to a cloud provider, bypassing Barman.

Note

Barman packages can be found in several different repositories. We recommend using PGDG repositories because it ensures compatibility, stability and access to the latest updates.

Warning

Do not upgrade Barman using different repositories. By doing so you risk losing your configuration as each source repository provides different packages, which use different configuration layouts.

RHEL-based distributions#

You can install barman, barman-cli and barman-cli-cloud using RPM packages on RHEL systems as well as on similar RHEL-based systems like AlmaLinux, Oracle Linux and Rocky Linux.

To begin with the installation, first install the PGDG RPM repository.

Important

The barman-cli-cloud scripts are part of the barman-cli package for RHEL-based distributions from PGDG. Therefore, you only need to install barman-cli to use the cloud scripts.

Important

The barman-cli-cloud package is included among the recommended packages when you install barman-cli.

Before starting the installation, it’s essential to evaluate your use case. If you don’t plan to use the barman-cloud client scripts, such as barman-cloud-backup, you can skip installing barman-cli-cloud as a recommended package when installing barman-cli. However, if you only intend to use the barman-cloud client scripts, you can install the barman-cli-cloud package on its own.
