Where are backups stored?

In the European Union, on S3 object storage operated by European providers. Object Lock immutability protects every backup: during the retention period, stored data can be neither modified nor deleted.

Because Cybee is a French vendor and the storage chain is European, your backups sit outside the scope of extraterritorial US legislation such as the CLOUD Act and FISA 702.

And since data is encrypted on your machines before transfer, with keys only you hold, even the storage provider never sees readable content.

Data residency, legal jurisdiction and cryptographic confidentiality: the three layers of EU data sovereignty, combined by design.
