GRAU DATA: sovereignty score and 8 European alternatives

GRAU DATA develops software for data protection, revision-proof archiving and metadata management. Its products include Blocky for Veeam, which protects backup data, FileLock for revision-proof archiving, MetadataHub for metadata management and XtreemStore, an S3-compatible object store that writes archives to LTO tape. The software is offered as an on-premise installation and, through a partner, as a managed service.

GRAU DATA GmbH is based in Schwäbisch Gmünd, Germany. The website does not state who owns the company. Because the software runs on the customer's own infrastructure, the data stays under the customer's control, which suits European organisations that want archive data kept under their own jurisdiction. Where XtreemStore is taken as a managed service through a partner, storage follows that partner's arrangements. The website does not describe GDPR commitments, so buyers of the partner service should request them directly.

Why digital sovereignty matters with GRAU DATA

GRAU DATA is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

GRAU DATA runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

GRAU DATA is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

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