Kubernetes Database Backup

A simple reliable database backup solution for Kubernetes and OpenShift.

Introduction

This Helm chart deploys a Kubernetes-native solution for backing up databases such as PostgreSQL, MySQL, and MongoDB to S3-compatible storage. It leverages Kubernetes CronJobs to schedule regular backups and stores them in a specified S3 bucket.

Architecture

Prerequisites

• Kubernetes 1.23+
• Helm 3.8+
• PV provisioner support in the underlying infrastructure
• S3-compatible storage account (AWS S3, Cloudflare R2, MinIO, etc.)

Features

• Supports PostgreSQL, MySQL, and MongoDB databases.
• Configurable backup schedules using Cron expressions.
• Stores backups in S3-compatible storage.
• Easy to configure and deploy using Helm.
• Supports multiple database instances and databases per instance.
• Retention policy for old backups.
