31 January 2013: Version 1.2.0 of Barman, Backup and Recovery Manager 
for PostgreSQL, has officially been released and is publicly available 
for download.
This major release introduces automated support for retention policies 
based on redundancy of periodical backups or recovery window.
Retention policies are integrated by a safety mechanism that allows 
administrators to specify a minimum number of periodical backups that 
must exist at any time for a server.
For a complete list of changes, see the “Release Notes” section below.

Backup retention policies:
A backup retention policy is an user-defined policy that determines how 
long backups and related archive logs (Write Ahead Log segments in 
PostgreSQL) need to be retained for recovery procedures. Through the 
‘retention_policy’ configuration option, Barman retains the periodical 
backups required to satisfy the current retention policy, and any 
archived WAL files required for the complete recovery of those backups. 
Barman users can define a retention policy in terms of backup redundancy 
(how many periodical backups, e.g. 5) or a recovery window (how long, 
e.g. 3 months).

Minimum redundancy safety:
Through the ‘minimum_redundancy’ configuration option, Barman controls 
the minimum number of backups available at any time in the catalogue for 
a specific server. This feature will protect users from accidental 
delete operations.

The open-source development of retention policies under GPL has been

the method for enforcing retention policies (currently only “auto”)
* Added the “minimum_redundancy” global/server option which defines the

minimum number of backups to be kept for a server
* Added the “retention_policy” global/server option which defines 
retention policies management based on redunancy (e.g. REDUNDANCY 4) or 
recovery window (e.g. RECOVERY WINDOW OF 3 MONTHS)
* Added retention policy support to the logging infrastructure, the 
“check” and the “status” commands
* The “check” command now integrates minimum redundancy control
* Added retention policy states (valid, obsolete and potentially 
obsolete) to “show-backup” and “list-backup” commands
* The ‘all’ keyword is now forbidden as server name
* Added basic support for Nagios plugin output to the ‘check’ command 
through the –nagios option
* Barman now requires argh => 0.21.2 and argcomplete
