Barman 1.2.1 released

Posted on June 17, 2013

2ndQuadrant is proud to announce the release of version 1.2.1 of Barman, Backup and Recovery Manager for PostgreSQL.

This minor release introduces support for bandwidth limitation through the "bandwidth_limit" option. This option allows administrators to set the maximum number of kilobytes per second for backup and recovery operations. Different bandwidth caps can be set for different servers.

More control on bandwidth limitations can be achieved through the "tablespace_bandwidth_limit" option that allows to cap the bandwidth usage for one or more specific PostgreSQL tablespaces.

By default, no bandwidth limitation is enforced, making Barman 1.2.1 fully compatible with configuration files from previous versions. This set of features gives administrators finer control on regular backup activities, reducing the impact of these operations on live systems.

Minor bugs have also been fixed.

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