Garage
AGPL-3.0Garage is a lightweight, self-hosted S3 object store that replaces Backblaze B2 with resilient geo-distributed replication across your own hardware.
Open-source alternative to — compare it against:
Overview
Garage is an open-source, S3-compatible distributed object storage engine built to run across modest hardware in different physical locations. Unlike complex enterprise storage clusters requiring dedicated datacenters and high-speed networks, it operates over ordinary internet links with minimal memory overhead. This design lets individuals and community operators pool disparate home machines or low-cost virtual servers into a resilient personal storage service.
Why Garage instead of Backblaze B2
Choosing Garage over Backblaze B2 centers on how storage integrates into your workflow. Backblaze B2 is a centralized cloud service that meters storage, API calls, and downloads behind an account dashboard and monthly credit card billing. Garage implements the standard S3 protocol on your own hardware, letting applications store and retrieve files without third-party accounts or bandwidth quotas. For workflows like syncing photos through Nextcloud, running automated backups with Rclone or Restic, or serving audio streams, Garage acts as a drop-in endpoint that keeps data within your private boundary.
The primary trade-off is operational maintenance. Backblaze B2 manages hardware procurement, disk replacements, and availability behind an automated cloud console. With Garage, your household or team assumes responsibility for provisioning nodes, opening network ports, and monitoring disk capacity. However, while Backblaze stores files in commercial facilities, Garage distributes replicas across whatever locations you choose, surviving broadband dropouts and power cuts through peer-to-peer synchronization.
What it does well
- Standard S3 protocol compatibility: connects directly to desktop file tools, backup utilities, and media servers without custom client software.
- Multi-location data replication: distributes copies of documents and media across separate properties, keeping archives safe if a disk or server fails.
- Low hardware requirements: runs on inexpensive single-board computers or older machines without demanding gigabytes of memory.
- Direct static website hosting: serves personal sites, documentation, and image galleries straight from storage buckets without a separate web server.
- Dynamic cluster rebalancing: redistributes stored data in the background when an operator adds extra drives or retires an aging machine.
