WBFSSync: A Complete Beginner’s Guide
What is WBFSSync?
WBFSSync is a file synchronization tool designed to keep files consistent across devices, locations, or services. It watches file changes and replicates updates (create, modify, delete) so multiple endpoints stay in sync without manual copying.
Key features
- Real‑time sync: Detects and propagates file changes quickly.
- Conflict handling: Uses timestamp and checksum rules to resolve simultaneous edits.
- Selective sync: Include/exclude files or folders by patterns.
- Cross‑platform support: Runs on Windows, macOS, and Linux.
- Transfer optimization: Uses delta transfers and compression to reduce bandwidth.
- Logging & monitoring: Detailed sync logs and optional metrics export.
Typical use cases
- Syncing developer project folders across machines.
- Backing up important directories to remote storage.
- Keeping shared team folders consistent.
- Mirroring content between on‑prem and cloud storage.
How WBFSSync works (high‑level)
- Watch: A file watcher monitors filesystem events or scans at intervals.
- Compare: Changes are compared using metadata (mtime, size) and checksums for safety.
- Queue: Detected operations are queued and optionally throttled.
- Transfer: Files are sent using optimized protocols (delta, compression).
- Apply: Remote endpoint applies changes; conflicts are resolved per policy.
- Verify: Optional post‑transfer verification ensures integrity.
Installation (assumed defaults)
- macOS / Linux: install via package manager or download binary, then place in /usr/local/bin and make executable.
- Windows: download installer or unzip portable release and add to PATH.
After installation, runwbfssync –versionto confirm.
Basic configuration (example)
Create a simple YAML config:
yaml
source: /home/user/projects target: sftp://backup.example.com/backup/projects include: - “/*.py” - “/*.md” exclude: - “/node_modules/” sync_interval: 60 # seconds for periodic scan conflict_policy: last_writewins
Run:
bash
wbfssync –config /path/to/config.yml start
Common commands
wbfssync init— generate a starter config.wbfssync start— begin continuous sync.wbfssync once— run a single synchronization pass.wbfssync status— show current sync state and queue.wbfssync logs –tail— stream recent logs.
Conflict resolution strategies
- Last write wins: Simpler but may overwrite important edits.
- Manual merge: Keep both versions and require user action.
- Versioned backups: Store multiple versions so you can roll back.
Choose based on team workflow and risk tolerance.
Performance tips
- Enable delta transfers for large files that change slightly.
- Exclude large, unchanging folders from frequent scans.
- Tune scan interval and debounce settings to reduce churn.
- Use checksums sparingly if metadata is sufficient to avoid CPU cost.
Security considerations
- Use encrypted transport (SFTP, HTTPS) for remote endpoints.
- Store credentials in OS keychain or environment variables, not plaintext configs.
- Enable server‑side encryption for cloud targets when available.
- Audit logs regularly for unexpected activity.
Troubleshooting checklist
- Check network connectivity and endpoint credentials.
- Inspect logs for specific error codes.
- Verify filesystem permissions for source/target paths.
- Ensure clock skew is small between machines (NTP).
- Run
wbfssync once –verboseto reproduce and diagnose.
Next steps for new users
- Install on a test machine and run a dry‑run (
–dry-run) against a small folder. - Validate conflict policy with simulated edits.
- Gradually increase scope and enable monitoring/alerts.
- Add regular backups/versioning before full rollout.
