Barman release notes

3.16.1 (2025-10-14)

Notable changes

• Automatic bucket creation added to barman-cloud-check-wal-archive

  The barman-cloud-check-wal-archive command now verifies whether the target bucket
  exists in the configured cloud storage (e.g., AWS S3) and automatically creates it
  if it does not.

  Previously, automatic bucket creation was handled by barman-cloud-backup. This
  change restores compatibility with CloudNativePG (CNPG) automations that depend on
  this behavior, which were affected after the release of Barman 3.16.0.

  In collaboration with the CloudNativePG team, we have reintroduced this
  functionality specifically in barman-cloud-check-wal-archive to ensure seamless
  operation of CNPG workflows and internal tests — all while preserving the intended
  behavior and simplicity for regular Barman users.
