DRIVUNO vs SpiderOak
SpiderOak pioneered 'no knowledge' backup. DRIVUNO brings that principle to a modern, fast product surface.
SpiderOak One popularised no-knowledge backup and remains a serious option for archival. DRIVUNO applies the same principle with modern cryptography (Argon2id, X25519, XChaCha20-Poly1305), streaming encryption for very large media files, browser-based access with no desktop agent required, and Live Clone for continuous 24/7 folder mirroring.
| Feature | DRIVUNO | SpiderOak |
|---|---|---|
| Zero-knowledge | Yes | Yes ('No Knowledge') |
| Access without installing an agent | Full web app | Desktop client centric |
| Large media handling | Streaming chunked encryption, multi-GB files | Backup oriented |
| Continuous folder mirroring (Live Clone) | Yes — live 24/7, encrypted on device, version history | Continuous backup, older sync engine |
| Team drives & encrypted mailbox | Built-in | Groups / separate products |
| Modern auth (passkeys, MFA, step-up) | Yes | Password-centric |

Frequently asked questions
Is this comparison fair?
+
We compare architectural and feature characteristics that are publicly documented by each vendor at the time of writing. We never describe a competitor as 'insecure' — only as 'not zero-knowledge by default' where that is the case.
What does zero-knowledge change in practice?
+
Your files are encrypted on your device with keys derived from your passphrase (Argon2id) before upload. DRIVUNO stores ciphertext and wrapped keys only, so there is no admin override, no content scanning, and nothing readable to disclose under legal pressure.
Can I mirror my computer folders continuously?
+
Yes. Live Clone watches one folder, several folders or a whole external disk on PC or Mac and clones every change to your vault in real time, encrypted on your device, with version history retained.
Can I migrate my existing files?
+
Yes. Upload folders through the web app — everything is encrypted client-side as it lands — or point Live Clone at the local copy of your current cloud folder and let it mirror itself.
How do I start?
+
Create a free account with 1 GB, encrypt your first upload in under a minute, and upgrade only when you need the space.
Your sensitive files deserve more than a traditional cloud.
Start free with 1 GB. Zero-knowledge encryption from the first upload — no admin override, no AI scanning, no plaintext on the server.
