How European enterprises can achieve digital sovereignty, compliance, and cost predictability with the right cloud architecture.

Defining a data backup strategy for your business is more than a technical task; it is a core pillar of digital sovereignty. Many EU companies feel locked into cloud providers due to complex pricing and exposure to non-EU laws like the CLOUD Act. A modern strategy for 2025 must prioritize EU data residency, transparent costs, and robust ransomware protection. This guide details how to build a resilient, compliant, and enterprise-ready backup framework using EU-based object storage, ensuring your data remains secure and under your control.

Schlüsselpunkte

  • A modern data backup strategy for business must prioritize digital sovereignty by using EU-only data centers to ensure GDPR compliance and avoid CLOUD Act exposure.
  • Eliminating egress fees and API call costs is critical for creating predictable margins, especially for MSPs offering Backup-as-a-Service.
  • Enterprise-ready storage should feature an "Always-Hot" model and immutable object locking to ensure instant data access and robust ransomware protection.

Prioritize Digital Sovereignty in Your Backup Plan

A strong majority of EU leaders want European solutions for critical infrastructure. Your data backup strategy must address the CLOUD Act exposure risk by design. Storing data exclusively in certified European data centers provides essential EU legal certainty. This approach is a key criterion for over 50% of organizations selecting a provider. True sovereignty is achieved when performance parity and cost transparency are guaranteed. Many decision-makers, nearly 84%, consider digital sovereignty business-critical. This shift prepares your infrastructure for future regulatory demands.

Demand Enterprise-Ready S3 Compatibility and Performance

Your backup tools require more than basic S3 API compatibility to function correctly. An enterprise-ready data backup strategy for business ensures support for advanced features like versioning and lifecycle management. This protects your investment in existing applications, requiring zero code rewrites for migration. We utilize an "Always-Hot" object storage model, making 100% of data immediately accessible. This avoids the restore delays and hidden fees common with complex tiering. Learn more about our cloud backup solutions. This architecture provides the strong read/write consistency needed for resilient recovery.

Implement Granular Access and Immutable Security

A modern data backup strategy for business hinges on robust identity and access management (IAM). Role-driven policies and multi-factor authentication (MFA) are the baseline for security. For ransomware defense, immutable storage with S3 Object Lock is a non-negotiable feature. It creates a WORM (Write-Once-Read-Many) state for your backup files. This makes data unchangeable for a set period, neutralizing many ransomware threats. Our platform also supports external identity providers via SAML/OIDC for seamless integration. Explore our approach to immutable backups. Key security features include:

  • Multi-layer encryption for data in transit and at rest.
  • Country-level geofencing to meet strict EU data residency rules.
  • Fine-grained permissions control through a first-class console UX.
  • Time-bounded access controls and presigned URLs for secure, temporary sharing.
  • EU-controlled key management, including all revocation procedures.

These integrated security layers form a critical defense against unauthorized access and data breaches.

Ensure Compliance with NIS-2 and the EU Data Act

Upcoming regulations redefine the requirements for your data backup strategy. The EU Data Act, applicable from September 2025, mandates data portability by design to prevent vendor lock-in. It requires that you can export all data, including metadata and versions. The NIS-2 directive demands a continuous security process, including supply-chain assurance and strict incident reporting timelines. Your cloud storage must be a partner in compliance, not a barrier. Our platform is built on these principles of data protection and backup. We operate exclusively in certified EU data centers to align with GDPR and other regional regulations. This focus on regulatory readiness gives your business a competitive advantage.

Leverage a Partner-Ready Platform for Predictable Margins

For MSPs and resellers, a successful data backup strategy for business depends on predictable economics. Our channel-focused model eliminates egress fees and API call costs entirely. This allows you to build BaaS and archiving services with stable, defensible margins. Our multi-tenant partner console simplifies management for hundreds of clients. We provide the tools for automation and reporting that MSPs need to scale efficiently. Recent distribution agreements with api in Germany and Northamber plc in the UK expand local access for our partners. Key benefits for partners include:

  1. Zero egress fees or API call costs for predictable margins.
  2. A multi-tenant console with RBAC and MFA for secure client management.
  3. Full automation capabilities via a 100% S3-compatible API and CLI.
  4. Fast onboarding processes to accelerate your time-to-market.
  5. Simplified compliance for GDPR-regulated workloads.

This partner-centric approach provides the foundation for mutual growth.

Build a Strategy with a Clear Exit Path

Vendor lock-in is a primary concern for over 70% of IT leaders. An effective data backup strategy for business must include a clear exit plan from day one. Our platform is built on open standards to ensure you always retain control. The complete absence of egress fees or minimum storage durations removes financial barriers to moving data. This preserves your negotiation power and long-term freedom of action. We provide guaranteed service levels and low latency via regional proximity. This focus on portability is central to a modern disaster recovery plan. Your data should be yours to move, manage, and control at all times.

FAQ

What is a sovereign data backup strategy?

A sovereign data backup strategy ensures that your data is stored and managed exclusively within a specific legal jurisdiction, such as the EU. It uses geofenced, EU-only data centers to comply with regulations like GDPR and protect data from foreign government access requests.


How does your storage solution help with ransomware protection?

Our solution provides ransomware protection through Immutable Storage using S3 Object Lock. This feature allows you to make your backup data unchangeable for a defined retention period, effectively shielding it from being encrypted or deleted by a ransomware attack.


Are there any hidden costs like egress or API fees?

No. Our pricing model is transparent and predictable. We have zero egress fees, zero API call costs, and no minimum storage durations, which eliminates the hidden fees common with other cloud storage providers.


Is your platform suitable for Managed Service Providers (MSPs)?

Yes, our platform is designed for MSPs. It includes a multi-tenant console, automation via API/CLI, detailed reporting, and a predictable pricing model without egress fees, which helps MSPs build profitable and scalable Backup-as-a-Service (BaaS) offerings.


How do you ensure compliance with regulations like NIS-2 and the EU Data Act?

We ensure compliance by operating exclusively in certified EU data centers, offering country-level geofencing, and providing features that support data portability and continuous security processes, which are core requirements of the EU Data Act and NIS-2 directive.


What does 'Always-Hot' object storage mean?

'Always-Hot' object storage means all your data is immediately accessible without any delays or restore fees associated with tiered storage (e.g., cool or archive tiers). This simplifies operations, ensures predictable performance for your applications, and speeds up recovery times.
