LTA-as-a-Service · archivage à valeur probante
Legally probative archiving.
As a managed service.
LTA-as-a-Service is the managed sovereign archive Rectangle built alongside a leading European digital trust provider — now distributed to regulated European teams.
Execution proof
100+ TB migrated off legacy public clouds — zero cutover data loss.
Rectangle has executed full data-footprint exits at production scale: migrating 100+ TB of probative archives from legacy public clouds straight into SecNumCloud-qualified infrastructure, with bit-for-bit integrity verification, signed chain-of-custody and zero cutover data loss for the operating business.
Sovereign archiving primitives
The substrate behind probative archiving.
Sovereign-hosted PostgreSQL
Managed PostgreSQL on Outscale SecNumCloud infrastructure — encrypted at rest, replicated in sovereign zones, with row-level isolation per tenant perimeter.
Secure object storage primitives
S3-compatible sovereign object storage with per-tenant KMS keys, immutable retention locks and signed per-object manifests for chain-of-custody.
Automated compliance logging
Every access, retention event and export is captured as signed, eIDAS-timestamped evidence — regulator-ready without reconstruction.
What you get
Probative value. Sovereign residency. Regulatory horizon.
- Aligned with NF Z42-013 — French standard for electronic archiving
- eIDAS-grade timestamps and qualified signatures
- Sovereign residency on Outscale SecNumCloud infrastructure
- Retention windows configurable per regulatory horizon (5 / 10 / 30 y)
- Audit export on demand — signed, verifiable, machine-readable
- Built with Europe's leading digital trust provider
Who it's for
Teams that need probative archiving — not a storage bucket.
- PDPs and Peppol operators archiving e-invoicing exchanges
- Health and financial institutions under HDS or DORA
- Public-sector and regulated operators with multi-decade retention
- AI and platform teams archiving prompts, plans and approvals
What it replaces
In-house probative archive projects that never quite ship.
- Object stores stitched together with custom signing pipelines
- Audit trails reconstructed under regulator pressure
- Non-sovereign storage holding regulated French records
- Multi-vendor integrations for timestamping and signatures
E-invoicing evidence
Archive structured Peppol exchanges and PDP/PA evidence per the French mandate.
Health & finance records
Long-term probative storage for regulated documents — HDS-aligned residency.
Ops & AI audit trail
Every signed plan and human approval becomes legally probative evidence.
Retention design review
Design your retention before the regulator asks.
A scoped review with a Rectangle engineer to map your evidence types, retention horizons, residency posture and export formats — before the first record is archived.
E-invoicing exchanges, signed plans, approvals, deploys, drift events, AI prompts.
5, 10 or 30 years — mapped to your regulatory perimeter and contract scope.
Sovereign zones on Outscale SecNumCloud infrastructure, with replica posture confirmed at plan time.
JSON, PDF and CSV regulator-aligned exports — signed and verifiable.
