Barman

What Barman is

Barman is a free, self-hosted tool for managing disaster recovery across PostgreSQL servers. It supports remote backups and local or remote recovery, including point-in-time recovery. Backup management includes catalogs, incremental and parallel operations, retention policies, and WAL archiving or streaming. Synchronous WAL streaming supports zero data loss (RPO=0). Remote transfers can use rsync over SSH or pg_basebackup, and recovery can run locally or over SSH. Barman integrates with PostgreSQL and archiving tools such as tar. It can compress WAL files with bzip2, gzip, or a custom method. Backup and WAL encryption with GPG depends on configuration; immutable storage is also available, with a required grace period in the current implementation. Barman runs on Linux or UNIX-like systems, uses an INI configuration file, and stores metadata locally. Its experimental cloud-streaming method is limited to S3-compatible destinations and does not support encryption or direct restores in Barman. The code is distributed under GPL-3.
