Barman 3.1.0 released

1 minute read

14 September 2022: EnterpriseDB is proud to announce the release of Barman version 3.1.0, a Backup and Recovery Manager for PostgreSQL.

Release Notes

  • Backups taken with backup_method = postgres can now be compressed using lz4 and zstd compression by setting backup_compression = lz4 or backup_compression = zstd respectively. These options are only supported with PostgreSQL 15 (beta) or later.

  • A new option backup_compression_workers is available which sets the number of threads used for parallel compression. This is currently only available with backup_method = postgres and backup_compression = zstd.

  • A new option primary_conninfo can be set to avoid the need for backups of standbys to wait for a WAL switch to occur on the primary when finalizing the backup. Barman will use the connection string in primary_conninfo to perform WAL switches on the primary when stopping the backup.

  • Support for certain Rsync versions patched for CVE-2022-29154 which require a trailing newline in the --files-from argument.

  • Allow barman receive-wal maintenance options (--stop, --reset, --drop-slot and --create-slot) to run against inactive servers.

  • Add --port option to barman-wal-archive and barman-wal-restore commands so that a custom SSH port can be used without requiring any SSH configuration.

  • Various documentation improvements.

  • Python 3.5 is no longer supported.

  • Bug fixes:

    • Ensure PostgreSQL connections are closed cleanly during the execution of barman cron.

    • barman generate-manifest now treats pre-existing backup_manifest files as an error condition.

    • backup_manifest files are renamed by appending the backup ID during recovery operations to prevent future backups including an old backup_manifest file.

    • Fix epoch timestamps in json output which were not timezone-aware.

    • The output of pg_basebackup is now written to the Barman log file while the backup is in progress.

  • We thank the following who contributed to this release:

    • barthisrael
    • elhananjair
    • kraynopp
    • lucianobotti
    • mxey
