pgBackRest Monitoring

What Is pgBackRest?

pgBackRest is a reliable, efficient, and secure backup solution for PostgreSQL databases. It offers advanced functionality for backup and restore, including full, differential, and incremental backups, along with support for parallelism, compression, and encryption. This ensures that your databases are efficiently managed and protected against data loss.

Monitoring pgBackRest With Netdata

Monitoring pgBackRest can be seamlessly integrated into your infrastructure using Netdata. Netdata uses an openmetrics (Prometheus) exporter for pgBackRest, allowing you to efficiently track metrics. Netdata’s pgBackRest monitoring tool can ingest data from any Prometheus exporter, automatically generating insightful dashboards and setting up alerts — all without needing a separate Prometheus server or Grafana setup. This integration simplifies the monitoring process and provides real-time visualization of pgBackRest’s performance metrics.

PostgreSQL backup strategy: pg_dump, pg_basebackup, and pgBackRest compared

Mon, 01 Jan 0001 00:00:00 +0000

Your backup tool determines your RPO, RTO, and whether you can restore to a point in time or only to the backup moment. This guide compares logical dumps via pg_dump, built-in physical copies via pg_basebackup, and the third-party tool pgBackRest. PostgreSQL 17 introduced native incremental physical backups. Operators must decide whether built-in capabilities are sufficient or whether to adopt alternatives such as Barman or WAL-G.

pg_dump and pg_dumpall: logical portability

pg_dump and pg_dumpall use an MVCC snapshot to produce a logically consistent SQL archive without blocking reads. Use --table or --schema for selective extraction. Parallel dumps use --jobs with directory format (-Fd) or custom format (-Fc):
