About Woodstock Backup
Woodstock Backup is a centralized backup solution designed to efficiently back up multiple hosts to a central server. With advanced deduplication, storage space is optimized.
Architecture and Technologies
Woodstock Backup combines several modern technologies to offer a robust backup solution:
- Client-server architecture: The server contacts clients to initiate backups, simplifying configuration and enhancing security
- Technologies: Entirely developed in Rust for the backend (4 microservices + the agent), with Vue 3 for the web interface
- Optimized storage: Uses a sophisticated chunk-based deduplication system with Blake3 hashing, organizing data in a hierarchical pool structure
- Security: Mutual TLS (mTLS) authentication and JWT tokens to secure communications
- Job queue: Asynchronous job processing via Valkey/Redis (Apalis framework) for reliable scheduling and execution
Woodstock Backup is open-source software distributed under the MIT license.
Key Features
- Modern interface with accessible API to launch, manage and monitor backups
- Native Windows compatibility without requiring rsync or SSH, works natively with all operating systems
- Block-based deduplication: Files are divided into 16 MB blocks (chunks) to optimize storage
- Cryptographic hashing system: Using Blake3 to identify and verify the integrity of data blocks
- FUSE filesystem access allowing you to mount any backup point as a normal directory
- Support for extended attributes and ACLs to preserve all file metadata
- Backup of computers with dynamic IP or intermittently connected to the network
Technical Architecture
Storage Pool Structure
The storage uses a "pool" system organized based on data block hashes:
- Chunks (blocks) are identified by their Blake3 hash
- Three-level hierarchical organization to optimize access
- Reference counting system to track block usage
- Optimized binary format (Protocol Buffers) for backup manifests
Authentication and Security
Security is based on multiple layers:
- mTLS certificates generated for each client device
- JWT tokens for application-level authentication
- Integrity verification based on cryptographic hashes
Why Woodstock Backup?
Woodstock Backup was developed to solve two major limitations of traditional backup solutions:
- Simplified Windows backups without dependency on rsync or SSH
- Easy access to backup data through FUSE filesystem mounting
