Last week, we examined Postgres XID wraparound complications in greater depth to see exactly how easily they can surprise even prepared enterprises. But we also found the real problem areas and how to mitigate them specifically. In this continuing series to plumb the depths of Postgres constructively, we’re going to focus on some of the […]
How can you achieve an RTO of 5 minutes for the backups of your PostgreSQL databases? And what about RPO=0 for zero data loss backups? To tackle such questions and more, 2ndQuadrant arranged a live webinar “PostgreSQL continuous backup and PITR with Barman”. The session was hosted by Gabriele Bartolini, Head of Support at 2ndQuadrant. […]
PostgreSQL 13 introduces two useful features to enhance automated validation of physical backups: backup manifests and a new tool called pg_verifybackup. In this short article I attempt to provide an overview of them.
Preamble How many current Barman users have thought about saving backups in a remote destination in the cloud? How many have thought about taking that backup directly from the PostgreSQL server itself? Well, since Barman 2.10 this is now possible! How? Let’s discover that together in the following articles.
The latest Barman 2.10 release introduces support for the system identifier of a PostgreSQL instance. In this article, I will answer a few questions explaining what a system identifier is and why it is a good thing that Barman uses it. What is the PostgreSQL system identifier? PostgreSQL gives a unique system identifier to every […]
Being a PostgreSQL database administrator and managing backups on a daily basis, one of the new features of Barman 2.10 that I liked the most is the transparent management of .partial WAL files during recovery. And, most likely, you feel the same if you have been using Barman with WAL streaming and have been asked […]
Barman 2.6 introduces support for geo-redundancy, meaning that Barman can now copy from another Barman instance, not just a PostgreSQL database.
Backups are a critical component to a fully covered Postgres database infrastructure. In some ways, it’s fair to say a database without a backup is no database at all—sometimes literally. 2ndQuadrant’s Barman tool is aptly named as a Backup And Recovery Manager for Postgres, and it exists primarily for encouraging a stable and robust backup […]
Today our Devops team at 2ndQuadrant, led by my dear friend and trusted colleague Marco Nenciarini, released version 2.3 of Barman.
In Part 3 of this series (here are Part 1 and Part 2), I would like to demonstrate how the development of a new feature for Barman would flow through the Kanban board.
