“Every waterfall begins with a single drop of water.” This bold yet simple statement reflects how VMware people come together as a community. Just as the greatest waterfall originates from a single drop of water, true change begins with a person choosing to take action. At VMware, we believe that our individual actions matter. They […]

In VMware Integrated OpenStack, we enable SSL encryption, by default, for users to access the various endpoints securely. In addition, we make it easy to generate your certificate signing request (CSR) and to apply the certificate after […]

2ndQuadrant is proud to announce the release of version 1.5.0 of Barman, Backup and Recovery Manager for PostgreSQL.

This major release features the get-wal command, which turns Barman into a WAL mine from which you can extract any transaction log file you need. Barman can now be easily integrated with any PostgreSQL standby server as a fallback method for WAL synchronisation.

Another important new feature is retry hook scripts that can be executed before or after a backup command or the archive of a WAL file. Differently from a standard hook script, already available in Barman, a retry hook script is executed indefinitely until it succeeds.

With version 1.5.0, Barman enhances its robustness, by adding checks on "wal_level" settings, by forbidding the deletion of a running backup, by requesting a successful "check" before initiating a backup, etc.

Barman now checks for conflicting paths, making sure that the same directory cannot be shared by more than a target (i.e. base backups, WAL archive, incoming directory, etc.), even across different servers within the same installation.

In terms of user experience, the "active" option grants users to temporarily disable a server in Barman, for operational purposes, while still accessing its catalogue.

Minor bugs have also been fixed.

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

Features in detail

Barman get-wal : No more standby servers that fall out of synchronisation with the master server, thanks to Barman's "get-wal" command. Design complex HA and DR architectures of PostgreSQL databases, knowing that you can now rely on an 'infinite' source of WAL files for any of your servers. Look at the "barman-wal-restore" script for an idea on how you can integrate "get-wal" with your PostgreSQL standby servers.

Retry hook scripts : You can now extend Barman by plugging your custom scripts before and after taking a backup operation or archiving a WAL file, knowing that Barman will repeat them until they succeed. You can now build your own pipeline around Barman, for example by storing a WAL in the cloud once it reaches Barman.
