EU Cloud Archive BYOK

Key capabilities BYOK storage targets: the customer supplies their own endpoint, bucket and keys. We never store or transmit documents on our infrastructure - we generate the object keys, retention manifest and the export payload; the upload itself runs against the customer's own credentials from their own job/script. Per-country retention rules seeded as data: France: 10 years for accounting books & supporting documents (Code de commerce art. L123-22 / art. L102 B LPF), 6 years for VAT/tax (art. L102 B LPF). Belgium: 10 years for accounting books (Code de droit economique art. III.86), 7 years for VAT (Code TVA art. 60). Netherlands: 7 years general (AWR art. 52), 10 years for real-estate (onroerende zaken) per Belastingdienst guidance. Retention-tagged manifest with SHA-256 fingerprint, legal-hold flag, destruction due-date and an immutable audit trail (chatter log with field tracking) recording every lifecycle transition per archived object. Mirror runs (batches) with draft -> queued -> mirrored -> verified state flow and a re-verification scan that re-hashes the Odoo source attachment against the recorded fingerprint to detect source tampering (the cloud-side copy is checked by your own tooling).
