We use Barman inside Kubernetes via CloudNativePG's plugin, as it is the default backup plugin.
Barman has always been solid for backup and restore, however configuring backup in CNPG is a little more interesting - WAL limits need to be set carefully or you just end up filling WAL volumes and the database becoming unavailable.
Last time I checked, Barman didn't support backups to S3. That's why (for us) pgBackRest was such a big deal: it could offload full and incremental backups to a basically limitless and reliable medium.
I think (and I'm probably wrong now) that Barman only could push backups to another Linux machine (e.g., EC2 box), so you had to worry about your backup system _on top_ of the main DB.
So I'm really hoping someone will pickup maintaining pgBackRest.
A shout out to Databasus (https://databasus.com). It’s a remarkably simply utility and web interface to schedule PostgreSQL backups. I use it in my homelab and works great.
This is a fantastic project that a lot of self-hosters using PostgreSQL use. Specially with pgBackRest archived by the owner on Apr 27, 2026, this is likely the leading option that has been around the block for a while.
Anyone here had considered Barman in the past, used it for a while and went to pgBackRest? Are you revisiting that decision now?
We (ParadeDB) use Barman via CloudNativePG for almost all our deployments. It's been solid, although I've had a few complaints about 1) inability to set S3 storage classes, 2) slow upload for very large databases.
Nonetheless, very happy to see this project on the front page of HN!
