28 September 2015: 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.
