Backblaze: sovereignty score and 8 European alternatives

Backblaze provides cloud storage and backup services. B2 Cloud Storage is object storage with an S3-compatible API, intended for businesses that want to store, archive or hand data to other tools. Computer Backup backs up Mac and PC computers for both business and personal use. The company started with computer backup in 2007 and launched B2 in 2015. Both services are delivered as SaaS.

Backblaze, Inc. is headquartered in San Mateo, California, and is listed on the Nasdaq. As a US company it can fall under US legislation such as the CLOUD Act. B2 offers the regions US West, US East, EU Central (Amsterdam, the Netherlands) and CA East (Toronto), so a European organisation can choose to store data in the Netherlands. The software is proprietary and not open source, and the services cannot be self-hosted.

Why digital sovereignty matters with Backblaze

Backblaze is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Backblaze hosts data in US, EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Backblaze is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Backblaze together with your other vendors and gives a total score, a heatmap and the main risk drivers.
