Barman vs Databasement

Barman is an open-source Python administration tool for PostgreSQL disaster recovery, designed for organizations managing business-critical databases. It supports remote backups of multiple PostgreSQL servers 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; recovery can run locally or over SSH. Barman integrates with PostgreSQL and standard archiving tools such as tar, and can compress WAL files with bzip2, gzip, or a custom method. GPG encryption for backups and WAL depends on configuration. Immutable storage is supported with a required grace period in the current implementation. Its experimental cloud-streaming method is limited to S3-compatible destinations and does not support encryption or direct restores in Barman. It runs on Linux and UNIX-like systems, uses an INI configuration file, and stores metadata locally. Barman costs nothing and is distributed under GPL-3.
