Achieve digital sovereignty and predictable costs with an enterprise-ready, S3-compatible object storage solution designed for Europe.

In 2025, the demand for a high-performance, sovereign, and fast Acronis alternative has intensified among European IT leaders. Escalating cloud costs, dependency on non-EU providers, and complex regulations like GDPR and NIS-2 are creating significant business risks. Many organizations feel trapped by unpredictable pricing models, including high egress fees, which hinder budget planning and operational flexibility. This article outlines a practical, enterprise-ready European alternative that delivers S3-compatible object storage with transparent costs, robust ransomware protection, and guaranteed data residency in certified EU data centers, ensuring you meet today's performance needs and tomorrow's compliance standards.

Schlüsselpunkte

  • A truly sovereign cloud storage solution operates exclusively in EU data centers, ensuring GDPR compliance and freedom from foreign laws like the CLOUD Act.
  • Transparent pricing without egress fees or API call charges is the most effective way to eliminate surprise costs and achieve predictable IT budgets.
  • Immutable backups using S3 Object Lock are a critical defense against ransomware, as they make data unchangeable even by privileged accounts.

Secure Data Sovereignty in Certified EU Data Centers

For European businesses, data sovereignty is a strategic priority, with 84% of decision-makers considering it a critical factor in vendor selection. Storing data with non-EU providers creates exposure to foreign laws like the CLOUD Act, a risk many are no longer willing to take. An EU-native platform eliminates this risk entirely by operating exclusively in European data centers. This ensures your data is governed solely by EU law, providing the legal certainty needed for a robust disaster recovery plan. This approach guarantees 100% GDPR compliance by design. This focus on EU-centric operations directly addresses the growing demand for digital independence.

Eliminate Unpredictable Costs with a Transparent Pricing Model

A recent study found that 95% of IT leaders have been surprised by hidden cloud storage costs, disrupting their budgets. The primary culprits are often egress fees and API call charges, which can make multi-cloud strategies economically unfeasible. A transparent pricing model with zero egress fees, no API call costs, and no minimum storage duration offers a predictable financial framework. This model can reduce total cloud storage costs by a significant margin. With a clear cost structure, you can scale your cloud backup solutions without fearing unexpected bills. This financial predictability is a key differentiator in a market where 67% of businesses expect their cloud costs to continue rising.

Achieve Seamless Integration with an Enterprise-Ready S3 API

Full S3 API compatibility is essential for protecting past investments and minimizing migration risk. It allows existing applications, scripts, and backup tools to work without code rewrites, a process that saves hundreds of development hours. An enterprise-ready solution supports not just basic object operations but also advanced capabilities. Here are some key features:

  • Full support for versioning and lifecycle management policies.
  • Seamless integration with leading backup tools like Veeam and NovaBackup.
  • Consistent performance for both API, CLI, and SDK access.
  • Support for event notifications to trigger automated workflows.
  • An "Always-Hot" architecture ensuring all data is immediately accessible with zero restore delays.

This comprehensive compatibility makes it the fastest S3 object storage for demanding workloads. This ensures that your technical teams can maintain operational continuity without a steep learning curve.

Fortify Ransomware Defenses with Immutable Backups

Cybersecurity studies show that 94% of ransomware attacks now attempt to compromise backups, making immutable storage a critical defense layer. Using S3 Object Lock creates a WORM (Write-Once-Read-Many) model, making backup files unchangeable and undeletable for a defined retention period. Even accounts with administrative credentials cannot alter or encrypt the locked data. This feature, combined with multi-layer encryption and Identity and Access Management (IAM) with MFA, provides a resilient defense. A proper backup strategy built on immutability ensures you can recover clean data after an attack. This proactive security posture is fundamental to modern data protection.

Meet 2025's Regulatory Demands for Data Portability and Security

New EU regulations are reshaping the digital landscape, and compliance is mandatory. The EU Data Act, fully applicable from September 2025, requires cloud providers to facilitate easy data switching and portability. The NIS-2 Directive also mandates stricter cybersecurity measures, including supply chain security and incident reporting within 24 hours. A compliant storage solution must be built to address these rules by design. Key readiness features include:

  1. Open standards and exportable formats for all data and metadata.
  2. No contractual or technical barriers that create vendor lock-in.
  3. Continuous security processes for patch and vulnerability management.
  4. Documented incident reporting timelines that align with NIS-2.

This built-in regulatory readiness provides a significant competitive advantage. It prepares your organization for the next wave of EU digital governance.

Empower Channel Partners with a Predictable and Scalable Model

For Managed Service Providers (MSPs) and resellers, predictable margins are essential for building a profitable business. A storage model with zero egress or API fees allows partners to offer Backup-as-a-Service (BaaS) and archiving solutions with stable, defensible pricing. The multi-tenant partner console simplifies management with RBAC and MFA. With distribution now available through partners like api in Germany and Northamber plc in the UK, local access for resellers is expanding. This partner-ready approach includes automation via API/CLI and streamlined reporting, enabling fast onboarding for solutions like Veeam backup storage. This focus on the channel ecosystem fosters strong, mutually beneficial growth.
