Comparison
Backblaze is excellent at cheap, reliable object storage and dead-simple computer backup. Blind Storage solves a different problem: provable privacy. We encrypt on your device before data reaches any server — Backblaze architecturally can read everything you store with them. Many teams use both: Backblaze B2 for raw storage economics, Blind Storage when the data itself must stay secret.
| Feature | Blind Storage | Backblaze |
|---|---|---|
| Zero-knowledge encryption (provider cannot read files) Backblaze offers optional private encryption key for Computer Backup, but it's bolt-on — not the default architecture. | ||
| Provider-agnostic (BYO S3 backend) | ||
| Open-source client | ||
| Secure file sharing B2 is raw object storage — no consumer sharing layer. | ||
| Zero egress fees (B2) Depends on your chosen backend; B2 itself has zero egress. | ||
| Unlimited computer backup agent | ||
| Lowest cost per terabyte | ||
| Server-side search & thumbnails Incompatible with true zero-knowledge — providers need plaintext. |
We're not here to pretend every product is worse at everything. Here's what Backblaze does better today:
Lower $/TB pricing
Backblaze B2 at ~$6/TB/month undercuts most providers on raw storage cost. Blind Storage charges for encryption, compliance, and portability — not bulk terabytes.
Mature, set-and-forget backup
Backblaze Computer Backup has 17 years of polish: install an agent, forget about it. Blind Storage is pre-launch and targets users who actively choose zero-knowledge — not passive backup.
Published reliability data
Backblaze publishes annual hard-drive failure stats — a rare transparency win. We're building toward independent audits (Cure53 / NCC Group) but don't have a decade of operational history yet.
Blind Storage encrypts on your device and works with any S3-compatible provider — including Backblaze B2 if you want their pricing with our privacy model.
