Unbiased Architectural Comparison
Why dewDrive is Different
Traditional cloud backup locks your data into proprietary silos with server-side keys. dewDrive gives you 100% cryptographic sovereignty and storage freedom.
| Capability | dewDrive | Traditional Cloud Backup |
|---|---|---|
| Encryption Architecture | Zero-Knowledge AES-256-GCM / ChaCha20 | Server-side key management (vendor holds keys) |
| Storage Freedom (BYO S3) | AWS S3, Wasabi, B2, MinIO, Local Disk, NFS | Locked to proprietary expensive cloud |
| Dual Backup Engine | Restic & Kopia native support | Closed-source blackbox engine |
| Disaster Recovery Cockpit | Time Machine instant point-in-time restore | Slow zip download or physical drive mail-in |
| Hardware & SSD Health Telemetry | Integrated 24/7 SMART & drive health daemon | None (requires separate RMM license) |
| Data Lock-in | Zero (Standard open snapshot repositories) | High (Cannot extract raw snapshots) |
1. True Zero-Knowledge vs “Encrypted at Rest”
Many backup providers advertise “encryption at rest”, meaning they hold the encryption keys and can decrypt your files upon subpoena or internal breach. With dewDrive, keys are generated on your local computer and never transmitted.
2. Zero Storage Markup
Traditional providers charge up to 5x retail prices for cloud storage. dewDrive connects directly to your own AWS S3, Wasabi ($6/TB/mo), or Backblaze B2 ($6/TB/mo) bucket without adding a single cent of markup.
