pgbackup-sidecar

pgbackup-sidecar is a lightweight Docker sidecar container designed to automate regular backups of a PostgreSQL database. It runs a cron job that periodically dumps the database, stores backups locally, and optionally sends logs to a webhook, simplifying backup management for PostgreSQL deployments.

Key Features

• Automated Backups — Uses pg_dump to create PostgreSQL database backups on a configurable schedule.
• Configurable Scheduling — Allows setting backup frequency via a crontab expression.
• Backup Rotation — Automatically removes old backups based on a configurable time interval.
• Webhook Integration — Optionally sends backup logs to a webhook for monitoring and notifications.

Philosophy

pgbackup-sidecar follows a minimal, single-purpose design, focusing on reliable and automated PostgreSQL backups with easy integration into Docker-based environments.
