How European businesses can leverage EU-based, S3-compatible storage to meet GDPR, NIS-2, and Data Act requirements without hidden costs.

In 2025, European IT leaders face a critical mandate: ensure digital sovereignty. With the EU Data Act coming into force and NIS-2 demanding higher security standards, relying on non-EU infrastructure introduces significant compliance risks and unpredictable costs. A majority of EU decision-makers now demand European solutions for their critical data, driven by the need for GDPR alignment and protection from foreign laws like the CLOUD Act. The solution lies in a new generation of compliant object storage, designed from the ground up for the EU market. This guide details how to achieve regulatory readiness, predictable costs, and robust ransomware protection with a sovereign-by-design storage architecture.

Schlüsselpunkte

  • True digital sovereignty requires a strictly EU-based provider to ensure data is governed exclusively by EU law, eliminating risks from foreign regulations like the CLOUD Act.
  • Compliant object storage must offer zero egress or API fees to provide predictable costs, a critical factor for both enterprises and MSPs offering BaaS.
  • S3 Object Lock is the core technology for creating immutable backups, which are essential for a modern ransomware defense and meeting compliance retention rules.

Establish Digital Sovereignty as a Strategic Asset

Digital sovereignty is no longer an IT-specific goal; it is a corporate necessity for over 70% of European businesses. True sovereignty means data is subject only to the laws of the jurisdiction where it is stored, a guarantee that simple data residency in an EU data center cannot provide. Storing data with a strictly European provider eliminates exposure to foreign data access laws. This strategic shift reduces compliance risks associated with GDPR by at least 25%. A truly compliant storage solution operates exclusively in certified European data centers with country-level geofencing. This ensures your most sensitive financial or customer data remains under EU control, transforming regulatory burdens into a competitive advantage. This foundation of control is essential before addressing architectural choices.

Demand S3 Compatibility That Protects Your Investments

Full S3 API compatibility is a baseline requirement for modern, compliant object storage. It ensures that your existing investments in backup tools, applications, and scripts remain functional, with some seeing a 100% reduction in code rewrites during migration. This compatibility must extend beyond basic operations to include advanced features like versioning, lifecycle management, and object tagging. Seamless integration with leading backup tools like NovaBackup is a key indicator of enterprise readiness. By preserving your operational workflows, a fully compatible object storage platform minimizes migration risk and protects technology investments that often exceed thousands of developer hours. The right architecture ensures these tools perform consistently.

Simplify Operations with an 'Always-Hot' Architecture

Complex storage tiering introduces fragility and hidden costs, with unexpected restore fees surprising nearly 40% of IT managers. An 'Always-Hot' object storage model eliminates this complexity by making 100% of data immediately accessible without delays. This design provides strong read/write consistency and predictable latencies, which is critical for mixed workloads. This model avoids the API timeouts and restore failures common with tiered systems. For businesses, this means operational simplicity and the assurance that data is always ready for recovery or analysis. An 'Always-Hot' approach is the bedrock of a resilient data protection strategy.

Build a Ransomware Defense with Immutable Storage

Ransomware attacks target backup data to prevent recovery, a tactic seen in over 50% of major incidents. The most effective defense is a compliant object storage solution featuring Immutable Storage with S3 Object Lock. This technology makes backup data unchangeable and undeletable for a defined period, rendering it immune to malicious encryption or deletion. An effective ransomware defense strategy includes these steps:

  • Implement a 3-2-1 backup rule with at least one immutable copy.
  • Use Object Lock in compliance mode to meet strict retention policies.
  • Regularly test your disaster recovery plan, reducing recovery time by up to 60%.
  • Combine immutability with granular Identity and Access Management (IAM) and Multi-Factor Authentication (MFA).

This creates a verifiable, audit-ready retention system that guarantees you can restore clean data after an attack. Such robust security is now a regulatory expectation.

Prepare for the EU's 2025 Regulatory Framework

Two key regulations redefine compliance for 2025 and beyond. The EU Data Act, applicable from September 2025, mandates data portability and interoperability, requiring cloud providers to offer a clear exit path without lock-in. The NIS-2 Directive, which EU states must adopt by October 2024, requires stronger, continuous security processes and supply-chain assurance for critical sectors. A compliant object storage provider builds these principles into its core operations, not as an afterthought. Choosing a platform designed for these regulations simplifies your compliance journey and demonstrates due diligence to auditors. This regulatory alignment must be matched by economic transparency.

Leverage Predictable Economics to Control Cloud Costs

Unpredictable costs, particularly egress fees, are a primary pain point for 65% of cloud customers. A compliant object storage solution built on a transparent economic model eliminates this risk entirely. By offering zero egress fees, no API call costs, and no minimum storage durations, the total cost of ownership becomes fully predictable. For MSPs, this model allows for stable, defensible margins on Backup-as-a-Service offerings. Enterprises benefit by avoiding surprise bills that can inflate storage costs by over 50% during large data recovery or migration events. This financial predictability is especially valuable for channel partners.

Empower Channel Partners with a Ready-Made Solution

For MSPs and resellers, a partner-ready platform is essential for growth. A compliant object storage solution should provide a multi-tenant console with robust role-based access control (RBAC) and MFA for secure client management. Automation via a full-featured API and CLI enables partners to integrate the storage into their existing service catalogs, reducing onboarding time by up to 75%. Recent distribution agreements with partners like api in Germany and Northamber plc in the UK expand local access for the channel. This ecosystem focus provides the tools needed to deliver sovereign backup and archive services efficiently. Now is the time to take practical steps.

Take Action: Your Next Steps Toward Compliance

Adopting a compliant object storage solution is a straightforward process. It begins with identifying data workloads that fall under strict sovereignty requirements. From there, you can configure storage buckets with country-level geofencing to meet specific regulations. Test the full S3 compatibility by connecting your existing backup software and running a trial migration and restore process. A successful test confirms zero disruption to your operations in under one hour. With a transparent pricing model, you can accurately forecast your budget without fear of hidden fees. Take the first step toward digital sovereignty and predictable costs. Talk to an expert to design your compliant storage strategy.

FAQ

How does your storage align with the EU Data Act?

Our platform is designed for the EU Data Act's principles of interoperability and portability. With full S3 compatibility and a strict no-egress-fee policy, we provide a guaranteed, cost-free exit path, ensuring you are never locked into our service and can move your data freely as the regulation requires.
