Starting point

In preparation for potential legal proceedings, data sets had to be preserved in a way that later proves their exact state at a specific point in time beyond doubt. A manual export is not enough — this requires cryptographically robust timestamps and a complete, reproducible process.

Solution

An automated preservation process that exports the relevant data daily, computes checksums and seals them with qualified RFC 3161 timestamps via an eIDAS-compliant trust service. Every run is logged; storage and certificate chain are organised to audit standards.

Outcome

An unattended system that has produced evidence-grade preservations every day since going live. Content and timing of each preservation can be proven without relying on third parties.
