Barman 2.11 released

3 minute read

9 July 2020: 2ndQuadrant is proud to announce the release of Barman version 2.11, a Backup and Recovery Manager for PostgreSQL.

This minor release introduces the barman-cli-cloud package, which contains all cloud related utilities previously released with version 2.10, such as barman-cloud-wal-archive and barman-cloud-backup, as well as 3 additional ones:

  • barman-cloud-wal-restore: script to be used as restore_command in PostgreSQL to directly retrieve WAL files from an object store such as AWS S3;
  • barman-cloud-restore: script to be used to retrieve a backup from an object store and prepare the recovery of a PostgreSQL instance;
  • barman-cloud-backup-list: script to be used to list the content of an object store.

If you are upgrading from version 2.10 and are already using barman-cloud-wal-archive or barman-cloud-backup, you must install the barman-cli-cloud package as described in the release notes.

In terms of security, Barman now supports non superuser connections to a PostgreSQL 10 (or higher) database. The user requires pg_read_all_settings and pg_read_all_stats privileges, as well as execution grants on some backup related functions. Please refer to the documentation for more details.

The upcoming PostgreSQL 13 is fully supported.

Minor bugs have also been fixed.

For a complete list of changes, please refer to the release notes for version 2.11.

Release notes

  • Introduction of the barman-cli-cloud package that contains all cloud related utilities.

  • Add barman-cloud-wal-restore to restore a WAL file previously archived with barman-cloud-wal-archive from an object store

  • Add barman-cloud-restore to restore a backup previously taken with barman-cloud-backup from an object store

  • Add barman-cloud-backup-list to list backups taken with barman-cloud-backup in an object store

  • Add support for arbitrary archive size for barman-cloud-backup

  • Add support for --endpoint-url option to cloud utilities

  • Remove strict superuser requirement for PG 10+ (by Kaarel Moppel)

  • Add --log-level runtime option for barman to override default log level for a specific command

  • Support for PostgreSQL 13

  • Bug fixes:

    • Suppress messages and warning with SSH connections in barman-cli (GH-257)
    • Fix a race condition when retrieving uploaded parts in barman-cloud-backup (GH-259)
    • Close the PostgreSQL connection after a backup (GH-258)
    • Check for uninitialized replication slots in receive-wal --reset (GH-260)
    • Ensure that begin_wal is valorised before acting on it (GH-262)
    • Fix bug in XLOG/WAL arithmetic with custom segment size (GH-287)
    • Fix rsync compatibility error with recent rsync
    • Fix PostgreSQLClient version parsing
    • Fix PostgreSQL exception handling with non ASCII messages
    • Ensure each postgres connection has an empty search_path
    • Avoid connecting to PostgreSQL while reading a file

If you are using already barman-cloud-wal-archive or barman-cloud-backup installed via RPM/Apt package and you are upgrading your system, you must install the barman-cli-cloud package. All cloud related tools are now part of the barman-cli-cloud package, including barman-cloud-wal-archive and barman-cloud-backup that were previosly shipped with barman-cli. The reason is complex dependency management of the boto3 library, which is a requirement for the cloud utilities.
