DRIVUNO vs Backblaze
Backblaze is excellent unlimited backup. DRIVUNO adds a zero-knowledge architecture and a full workspace on top of continuous mirroring.
Backblaze Personal Backup offers continuous, unlimited backup of a computer at a very low price, with an optional private encryption key — but that key is transmitted to Backblaze's servers during a restore, so plaintext recovery passes through the provider. DRIVUNO's Live Clone provides the same continuous mirroring with a strict zero-knowledge model: keys never leave your device, not even on restore, and your files also live in a real workspace with sharing, teams and an encrypted mailbox.

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.
