Comet Backup: sovereignty score and 8 European alternatives

Comet Backup is a backup platform for managed service providers and IT teams, protecting workstations, servers, virtual environments, Microsoft 365 and databases. The management console can be hosted in the cloud or self-hosted, and backup storage can be Comet Storage, any S3-compatible cloud or on-premises infrastructure. It is part of the WebPros group.

The operating company is Comet Licensing Ltd., established in New Zealand with a registered address in Christchurch. Its privacy policy applies GDPR principles across the group and describes Comet Licensing as a processor for stored backup content under a data processing agreement. WebPros International GmbH, based in Schaffhausen, Switzerland, is named for data subject requests. The policy does not state where Comet-hosted storage and console data are located, and the object storage is run by an unnamed third-party provider. A European organisation can self-host the console and keep backups on its own or EU-based S3-compatible storage.

Why digital sovereignty matters with Comet Backup

Comet Backup is headquartered in NZ, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Comet Backup 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.

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