Enterprises face growing pressure from unpredictable cloud costs and complex data sovereignty laws. A truly European S3 compatible cloud archive solution offers a practical path to control, compliance, and cost efficiency.

Key Takeawys

Choose a sovereign-by-design S3 compatible cloud archive solution that operates exclusively in EU data centers to eliminate CLOUD Act exposure and ensure GDPR compliance.

Prioritize providers with an 'Always-Hot' storage model and no egress or API fees to reduce operational complexity and achieve predictable, transparent costs.

Verify that your provider is ready for the EU Data Act and NIS-2 directive to turn future regulatory requirements into a competitive advantage.

A majority of EU decision-makers now demand European solutions for their critical data infrastructure. The challenge lies in finding S3 compatible cloud archive solutions that deliver performance parity and cost transparency without vendor lock-in. This article outlines a checklist for selecting an enterprise-ready EU alternative. It focuses on achieving digital sovereignty, ransomware protection, and predictable economics, exploring how an 'Always-Hot' architecture simplifies operations and ensures your data remains under EU legal control, permanently.

Secure EU Data Residency and Eliminate CLOUD Act Exposure

Many EU enterprises view dependence on non-EU providers as an excessive risk. The US CLOUD Act creates a direct conflict with GDPR, challenging data sovereignty. An EU-owned provider eliminates this risk entirely.

Our solution is sovereign by design, operating exclusively in certified European data centers. We provide country-level geofencing to guarantee data residency under strict EU rules. This ensures 100% EU legal certainty for all archived data.

For regulated industries like financial services, this alignment is a competitive advantage. It simplifies compliance for every workload. This foundation of sovereignty prepares your architecture for the future.

Leverage Advanced S3 Compatibility for Seamless Migration

True S3 compatibility protects your existing technology investments. Our platform supports advanced capabilities like versioning and lifecycle management across any API, CLI, or SDK. This ensures your applications continue working after a 1-hour migration.

An enterprise-ready solution must minimize migration risk and protect past investments. We offer out-of-the-box integrations with leading backup tools, including a deep collaboration with NovaBackup. Your existing scripts and pipelines run without code rewrites.

This comprehensive compatibility provides a clear exit path from complex providers. It preserves your freedom of action for the long term. This focus on interoperability is the next critical component.

Simplify Operations with an Always-Hot Storage Architecture

Complex tiering models create hidden operational costs and restore delays. An 'Always-Hot' object storage model ensures all data is immediately accessible with zero restore surprises. This approach avoids fragile lifecycle policies that cause API timeouts.
Our architecture is built for consistency and scale, delivering predictable latencies. It handles millions of small files or large archival patterns with strong read/write consistency. This model reduces operational complexity by over 30%.
Here is how an always-hot model benefits your team:

  • Eliminates tier-restore delays for urgent recovery needs.

  • Keeps third-party backup and analytics tools stable and performant.

  • Avoids hidden fees associated with data retrieval from cold tiers.

  • Reduces lifecycle policy drift and simplifies data management.
    This resilient design provides the foundation for robust data protection strategies.

Deploy Immutable Storage for Resilient Ransomware Protection

Ransomware threats require modern, resilient data protection measures. Our Immutable Storage with Object Lock makes data unchangeable for a defined period. This feature is a core defense for audit-ready retention.

We combine immutability with multi-layer encryption for data in transit and at rest. Identity-based IAM with MFA and role-based access control (RBAC) provides granular security. This architecture eliminates single points of failure in your security posture.

These security measures are managed under EU-controlled key management and revocation procedures. This ensures your defenses are as sovereign as your data. Next, we examine how this aligns with new EU regulations.

Gain a Competitive Edge with Proactive Regulatory Readiness

Upcoming EU regulations create new compliance burdens for unprepared businesses. Our platform is designed for future requirements, turning regulatory readiness into your advantage. We align with two key 2025 directives.

The EU Data Act, effective from September 2025, mandates data portability and interoperability. Our design proves a real exit path with no lock-in. The NIS-2 Directive requires continuous security processes and supply-chain assurance. Our operations have baked-in NIS-2 principles from day one.

This proactive stance on compliance simplifies your governance challenges. It ensures your archiving strategy remains secure for years. This readiness also extends to our economic model.

Achieve Predictable Archive Costs with a Transparent Economic Model

Most companies feel locked into providers due to complex pricing. Our economic model is predictable by design, with zero hidden fees. This transparency is a key driver for businesses seeking EU alternatives.
We guarantee a straightforward financial model for all S3 compatible cloud archive solutions. You can expect the following:

  1. Zero egress fees, no matter how much data you retrieve.

  2. Zero API call costs, ensuring predictable application performance.

  3. No minimum storage duration, providing complete flexibility.
    This approach provides guaranteed service levels as reliable inputs for business planning. It allows you to scale your disaster recovery capabilities without financial surprises. This predictability is especially valuable for our partners.

Enable Partner Success with Predictable Margins and Support

For MSPs and resellers, unpredictable costs erode margins. Our partner-ready model ensures you can build profitable Backup-as-a-Service and archiving offerings. The zero-egress model creates stable, defensible margins for every client.

Our partner console offers multi-tenant management with RBAC and MFA. It includes robust reporting and automation via API/CLI for fast onboarding. We expanded local access in 2025 with key distributors.

We are proud to work with the distributor api in Germany. We also welcomed our first UK distributor, Northamber plc. This growing ecosystem makes it easier than ever to deliver sovereign cloud solutions.
