At Dalibo we are actively working on a pgBackRest plugin for PostgreSQL clusters deployed with CloudNativePG. Here is the announcement of the 0.0.3 version that has just been released.
Backup tools
The PostgreSQL ecosystem is full of tools in various areas. For physical
backups, two tools are primarily used by administrators in addition to
pg_basebackup tool: Barman and pgBackRest.
CloudNativePG relies, by default, on Barman to create and restore physical backups and also archive WAL files. More specifically, it is based on barman-cloud suite from the Barman project.
The strength of PostgreSQL lies in the plurality and free choice of tools within its wide ecosystem.
We do love pgBackRest for bare metal or virtualized environments and wanted to see this tool also available for CloudNativePG.
People behind CloudNativePG allow new tools to be easily plugged thanks to the CNPG-I project. And here we are with pgBackRest.
Our plugin
For some time now, we have been developing a plugin based on pgBackRest to manage backups of our clusters. The plugin is, of course, open source and can be found on our GitHub page right here https://github.com/dalibo/cnpg-plugin-pgbackrest.
What we are trying to do is offer an alternative based on a well-known and recognized tool.
Version 0.0.3 of the plugin is now available. Here’s what you can do with it:
- WALs archiving (using pgBackRest async feature)
- Taking and restoring backup (on S3 solutions or Azure Blob Storage)
- Point-in-Time Recovery
- Creating secondary based on Log Shipping
As you’ve probably guessed, this is an experimental plugin. We would be very happy to receive feedback from your tests to improve what we already did.
Have a look at the project, the documentation and feel free to test it !
