Data Sovereignty and Compliant Backup
Where your backup data lives — and whose laws reach it — is now a compliance question. Storware runs an EU-based control plane outside US jurisdiction, and turns backup into a compliance artifact: immutable, auditable, and retained on your terms.
Key Highlights
EU control plane, outside US reach
Storware is headquartered in Warsaw, with EU-based engineering, support, and control-plane operations — beyond the extraterritorial reach of the US CLOUD Act.
Backup as a compliance artifact
Immutability, audit logging, and configurable retention turn backup copies into tamper-evident, auditable evidence — not just recovery points.
Built for NIS2, DORA, and GDPR obligations
Supports the supply-chain, ICT third-party, and data-control expectations these frameworks place on your backup layer
You choose where data resides
Keep backup data in the jurisdiction you require — EU data centers, on-prem, or your own object storage — on destinations you control.
Sovereign, auditable data protection
EU-based control plane and support
Control-layer sovereignty by design: the platform operating your backups sits under EU jurisdiction, not a US-parent hyperscaler.
Immutable, tamper-evident copies
Object Lock and Retention Lock protect backup data from modification or deletion during a defined retention period — the integrity auditors look for.
Audit logging and configurable retention
Auditable records of backup and recovery operations, with retention policies you can align to legal and sector-specific requirements.
Data residency control
Direct control over destinations — EU data centers, on-prem storage, or your own S3-compatible object storage — so data stays in-jurisdiction.
Recovery testing as evidence
Recovery Plans and scheduled testing produce documented proof that recovery works — the demonstrable operational assurance DORA expects.
Supply-chain transparency
A named EU vendor with documented architecture and support, so you can evidence your backup provider in a NIS2 supply-chain assessment
ISO-aligned security controls
Encryption in transit and at rest, RBAC, and MFA, under recognized information-security standards.
One platform across your regulated estate
The same sovereign, auditable protection across VMs, cloud, containers, storage, and databases — under one universal license.

Why an EU control plane matters for NIS2, DORA, and GDPR
A short explainer on the difference between data residency and data sovereignty — and why the control layer, not the contract, decides which law reaches your backups.
Sovereignty can't be achieved by contract
For a US-headquartered provider, the CLOUD Act and GDPR create a tension no contract has resolved. Control-layer sovereignty is architectural — it comes from who operates the platform, and under which jurisdiction.
The data layer
Where backups physically reside. Necessary, but not sufficient — residency alone doesn't govern who can legally compel access.
The control layer
Who operates the platform managing your backups. If that operator is US-headquartered, US law reaches the control plane wherever the data sits. Storware's control plane is EU-based.
The legal layer
Which jurisdiction can compel disclosure. The EU-US Data Privacy Framework covers commercial transfer, not government access — an EU control plane keeps this layer in the EU.
What does data sovereignty mean for backup?
It’s not only where your backup data physically resides, but whose legal jurisdiction can compel access to it. Full sovereignty needs all three layers in the right place: the data, the control plane operating it, and the law that governs disclosure.
Is Storware subject to the US CLOUD Act?
No. Storware is headquartered in Warsaw, Poland, with EU-based engineering, support, and control-plane operations — outside the extraterritorial jurisdiction the CLOUD Act creates for US-headquartered providers.
How does Storware support NIS2 compliance?
As a named EU-based backup provider with documented architecture, immutability, and audit logging, Storware helps you evidence your data protection layer in a NIS2 supply-chain assessment. NIS2 is a directive, so obligations depend on your member state’s transposition — check your national authority.
How does Storware support DORA?
DORA has been uniformly enforceable across the EU since January 2025. Storware supports its ICT third-party and operational-assurance expectations through immutable backups, tested recovery, and auditable records. Your specific obligations should be confirmed with your compliance team.
Does hosting in an EU data center make my US-based backup vendor compliant?
Not on its own. Residency governs where data sits; it doesn’t change whose law can reach the control plane. If the platform operator is US-headquartered, US jurisdiction can still apply. Sovereignty is decided at the control and legal layers, not by a residency clause.
Can I control where my backup data is stored?
Yes. You choose the destinations — EU data centers, on-prem storage, or your own S3-compatible object storage — so data stays in the jurisdiction you require.
How does backup become a "compliance artifact"?
Through immutability, audit logging, and configurable retention: tamper-evident, auditable records of what was protected, when, and for how long — evidence you can present, not just data you can restore.
Does Storware guarantee regulatory compliance?
No platform can make an organization compliant on its own. Storware provides sovereign, auditable, immutable data protection that supports your obligations under NIS2, DORA, and GDPR — your DPO and legal team determine how it maps to your specific requirements.
