Deja Dup: sovereignty score and 8 European alternatives

Déjà Dup is a simple backup tool for the GNOME desktop, aimed at recovering from accidental loss of personal data. It uses Restic behind the scenes, compresses and encrypts data before it is backed up, and makes incremental backups so that you can restore from any particular backup. Backups can be scheduled and written to local drives, network servers or cloud services. You install it on your own Linux desktop, for example via Flathub.

Déjà Dup is free software released under the GPL-3.0-or-later and developed in the open as a GNOME project. It is not a hosted service: the software runs on your own device, and your data ends up wherever you point the backup, be it a disk you control, a server of your own or a cloud provider. The sovereignty of a backup therefore depends on the storage target you choose; with an EU-based target or your own hardware, no non-European provider is involved.

Why digital sovereignty matters with Deja Dup

Deja Dup 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.

Data is hosted exclusively in the EU, so Deja Dup scores best on data residency.

Deja Dup is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

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