Rclown 🤡

A friendly web UI for backing up your object storage buckets by Marc Köhlbrugge.

Rclown wraps the battle-tested rclone in a simple interface. Schedule backups, see what's happening, get notified when something breaks. Supports Cloudflare R2, Backblaze B2, Amazon S3, and other S3-compatible providers.

• Multi-provider support: Cloudflare R2, Backblaze B2, Amazon S3
• Bucket discovery: Automatically find and import buckets from your providers
• Scheduled backups: Daily or weekly, with dry-run support
• Flexible paths: Back up entire buckets or specific sub-paths
• Retention policies: Deleted files kept for configurable period before cleanup
• Comparison modes: Size-only, checksum, or default (size + mtime) comparison
• Live logs: Stream backup progress in real-time
• Failure notifications: Email alerts when backups fail
• System health: Monitor CPU, memory, disk usage, and queue status

Rclown is designed for self-hosting. The Docker images include everything you need (Ruby, SQLite, rclone).

The easiest way to self-host Rclown is with our pre-built Docker images. See Docker Deployment for details.
