Barman v2.10 Now Available

2ndQuadrant today announced the release of Barman version 2.10.

Barman [https://www.2ndquadrant.com/en/resources/barman/] (Backup and
Recovery Manager) is an open source administration tool for managing backup
and disaster recovery of PostgreSQL servers. It allows you to perform
remote backups of multiple servers in business-critical environments and
helps DBAs during the recovery phase.

This release introduces verification of the PostgreSQL instance’s system
identifier in the check command to prevent users from executing commands in
Barman in case there are any inconsistencies between the situation on the
disk and the live information coming from the PostgreSQL connection(s).
Barman will prevent users from taking a backup or archiving a WAL file on
an existing folder that contains data from another instance with a
different identifier.

Barman 2.10 automates recovery of .partial WAL files coming from streaming
replication, making RPO=0 easier to achieve, with barman-wal-restore (in
barman-cli package) and get-wal commands.

A new server/global option called create_slot controls automated creation
of the replication slot, where required (streaming_archiver must be
enabled, and slot_name defined). If set to auto, Barman automatically
creates the slot_name replication slot in PostgreSQL. By default, this
option is set to manual for back-compatibility.

Barman 2.10 brings two new utilities to the barman-cli package:

- barman-cloud-wal-archive: a script to be used as archive_command in
PostgreSQL to directly ship WAL files to AWS S3 for permanent storage in
the cloud.
- barman-cloud-backup: a script to be used to perform full base backups
from the PostgreSQL server in tar format and to ship them directly to AWS
S3 for permanent storage in the cloud.

Both utilities rely on the boto3 Python library. The equivalent restore
commands to these will be added in a future release. Until then,
restoration is manual - for example, you can make use of the AWS client to
retrieve files from S3 buckets.

The barman-cli package, which contains "Barman Client Utilities", is
recommended on those servers where PostgreSQL instances are running.

Minor bugs have also been fixed.

We strongly recommend upgrading to Barman v2.10 at the earliest opportunity
available.
