Using MinIO as a Backup Target for Rancher Longhorn

Sat, 26 Oct 2024 11:45:00 -0500

Longhorn, an open-source container-native storage system developed by Rancher, simplifies persistent volume backups by supporting S3 and NFS storage systems as backup targets. In this guide, we’ll walk through how to configure MinIO as an S3-compatible backup target for Longhorn, enabling reliable volume backups.

This post assumes that Longhorn and MinIO are already installed—for installation guides, refer to the official Longhorn documentation and MinIO Quickstart Guide.

Environment Overview

MinIO version: RELEASE.2021-08-17T20-53-08Z (deployed with Podman on SUSE SLES 15 SP2)
Longhorn version: 1.1.1 (installed via Rancher’s Application Catalog on an RKE cluster running Kubernetes 1.20.9-rancher1-1)

Step 1: Configure MinIO for Longhorn Backups

First, we’ll set up MinIO storage by creating a dedicated bucket, folder, user, and policy for Longhorn backups. Use MinIO’s command-line tool, mc, to manage these objects.
