Year and Month Folder Organization
Keep your photo archive organized by automatically sorting media into YYYY/MM (e.g. 2026/11) or YYYY-MM subfolders on your remote storage.

Preserve Original Quality
Upload original HEIC, ProRAW, DNG, and 4K MOV video files without compression or format conversion.

Smart Incremental Sync
Only new or modified files are uploaded, saving bandwidth and time. Optional SHA-256 checksum verification ensures data integrity.

Safe Dry-Run Preview
Simulate your backup before transferring to preview exactly which files will be uploaded, updated, or skipped.

Intelligent Background Automation
Schedule backups to run automatically when connected to Wi-Fi, while charging, or during designated quiet hours.

Local-First Security and Privacy
Credentials and SSH keys are stored exclusively in the iOS Keychain. Your files never pass through third-party servers; data travels directly from your device to your server.
