Barman 1.3.0 released

2ndQuadrant is proud to announce the release of version 1.3.0 of Barman, Backup and Recovery Manager for PostgreSQL.

This major release has a new code infrastructure in terms of output, subprocesses, remote commands, file system, events (‘hooks’) and metadata management, making the application more robust.

Barman 1.3.0 introduces a few configuration options for:

  • managing hook scripts before and after archiving a WAL file
  • network compression of remote backup, and
  • recovery operations and immediate checkpoint at backup time

Administrators can now force a rebuild of the xlog.db file (WAL archive) through the 'barman rebuild-xlogdb' command.

This major version now correctly handles those tablespaces that had been created inside the PGDATA directory, removing content duplication.

Remote recovery code has been improved in order to behave exactly like local recovery does, including preparation of the directories layout (PGDATA and tablespaces).

Minor bugs have also been fixed.

Many thanks for funding towards the development of this release go to Ecometer (www.ecometer.it), Agile Business Group (www.agilebg.com) and a French company (that prefers to remain anonymous).

For a complete list of changes, see the “Release Notes” section below.

  • Refactored hook scripts management
