Backup ONE: sovereignty score and 8 European alternatives

Backup ONE is a Swiss cloud service for business backup and storage. The offering covers workstation and server backup, backup of Microsoft 365 and Google Workspace, backup of Synology and QNAP NAS systems, backup to S3 storage and managed backup run by its own security operations centre. Everything is controlled from one management console. According to the vendor, you can set your own encryption key per plan (zero-knowledge), and an antivirus and anti-ransomware module is built into the software. Backup schedules, compression and bandwidth limits are configurable.

Backup ONE AG is headquartered in Bern, Switzerland. The vendor states that all data and metadata are stored encrypted in Switzerland, geo-redundantly, and that staff have no access to customer data; lost keys cannot be recovered. No parent company is named. The privacy policy refers to Swiss data protection law. Switzerland is not an EU member but an EFTA country with an EU adequacy decision. For a European organisation, this is a Swiss backup service with data storage in Switzerland.

Why digital sovereignty matters with Backup ONE

Backup ONE is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Backup ONE hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

Backup ONE 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 Backup ONE together with your other vendors and gives a total score, a heatmap and the main risk drivers.
