Frequently Asked Questions

How long does the initial backup take?

Initial backup duration depends on your file volume and internet speed. Backblaze targets completion within 30 days. Smaller files upload faster than large media files. Keeping your computer on continuously and minimizing internet usage accelerates the process significantly.

Can I back up external drives?

Yes, Backblaze supports unlimited external USB drives, portable hard drives, and SD cards connected to your computer. Connect all drives simultaneously for fastest backup. Backblaze automatically includes them when detected and selected in settings.

What happens if I cancel my subscription?

After cancellation, your backed-up data remains accessible for 30 days. After 30 days, your backup is permanently deleted from Backblaze servers. Reactivating your subscription within 30 days restores access to your backup without re-uploading.

Is my data encrypted and private?

Backblaze encrypts all data during transmission using SSL/TLS. Optional private key encryption (zero-knowledge mode) enables additional client-side encryption where Backblaze cannot access your encryption keys, maximizing privacy.

Can I restore files from the web browser?

Yes, the web restore portal allows browsing and downloading files directly from backblaze.com/user_signin.htm. You can search files, view version history by date, and download individual files without installing software.

Does Backblaze support multiple computers?

No, each subscription covers one computer only. Multiple computers require separate subscriptions at $9/month per computer. However, one subscription can back up unlimited external drives on that single computer.
