Barman 3.1.0

on GitHub

Version 3.1.0 - 14 September 2022

Features

• 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.
