Barman 2.2 Backup and DR Manager for PostgreSQL Databases From 2ndQuadrant

Implementation of parallel copy for backup/recovery through parallel_jobs option, performing copies at an accelerated rate, speeding up backup and recovery process for rsync copy method

2ndQuadrant Limited announced Barman 2.2.

It is a backup and DR manager for PostgreSQL databases.

This release boasts an awaited feature: the implementation of parallel copy for backup/recovery through the parallel_jobs option. This anticipated feature allows Barman to perform copies at an accelerated rate, speeding up the backup and recovery process for the rsync copy method.

Subito.it, long time partners of the company and sponsor of the Barman project, participated in early testing of the parallel copy feature.

This feature has been a goal of the development team for some time.

Parallel copy fills an important gap for Barman in very large database (VLDB) scenarios, by giving users flexibility and freedom in architecture design to help them reduce both backup and recovery times sensibly,” said Gabriele Bartolini, one of lead developers, Barman. “This feature takes advantage of the code refactoring activity that has been previously performed with 2.0 and 2.1 releases, including the thousands of automated tests that help us make Barman more robust.

Other features in this release include:

  • Support custom WAL size (PostgreSQL 8.4 and up)

  • Improve check command

  • Add external_configuration to backup_options

  • Add -get-wal and -no-get-wal options to barman recover

  • Add max_incoming_wals_queue global/server option for the check command

  • Documentation improvements

Additionally, several minor bug fixes have also been implement——–ed.

Navionics SPA, a manufacturer of electronic navigational charts and founding sponsor of the Barman project, migrated its systems to PostgreSQL in 2012. With several servers under Barman backup, the Navionics team stated that they are proud to have contributed again in the developing of a new Barman release that includes parallel jobs.

We have been a sponsor of Barman since the first release because we need a reliable system and DR [capability] for our production servers,” stated DBA team, Navionics.”We are sure that [parallel copy within Barman] will allow us to have faster backup and restore for our huge databases.
