DataTrust Backup: sovereignty score and 8 European alternatives

DataTrust Backup is a managed backup and archiving service from DataTrust AG. It protects data from Windows, macOS and Linux computers and Synology NAS devices, plus Microsoft 365 with mailboxes, SharePoint and OneDrive. Data travels encrypted over a secured internet connection to the data centre and is stored immutably. By default the service retains data for ten years, and for twenty years on request, for example for accounting or patient records. The team monitors the backups daily and steps in when a job fails.

DataTrust AG is headquartered in Wil (SG), Switzerland: outside the EU, but Switzerland is an EFTA member with a European adequacy decision. According to the vendor, the data is held in two geographically separate data centres in Switzerland and mirrored every day. For a European organisation this means Swiss law and Swiss storage, with no large US cloud provider named in the chain. Do ask about the data processing agreement and about who manages the encryption keys, as this is not described.

Why digital sovereignty matters with DataTrust Backup

DataTrust Backup 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.

DataTrust Backup 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.

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