Finding an Acronis compatible backup storage provider that guarantees EU data sovereignty is a significant challenge. Many providers have EU data centers but remain subject to non-EU laws, creating compliance risks. This article outlines how to select a truly sovereign storage partner that offers predictable costs and robust security.

The topic briefly and concisely

Choose an Acronis compatible backup storage provider that is 100% European-owned and operated to ensure true GDPR compliance and avoid US CLOUD Act exposure.

Eliminate unpredictable costs by selecting a provider with zero egress fees and no API call charges, ensuring restores and backups don't inflate your bill.

Protect your Acronis backups from ransomware by using a storage provider that offers S3 Object Lock for immutable, unchangeable data copies.

For UK and European businesses using Acronis, selecting a backup storage provider extends beyond simple capacity and speed. True digital sovereignty requires a partner whose infrastructure and legal framework are exclusively European, eliminating exposure to regulations like the US CLOUD Act. An ideal Acronis compatible backup storage provider delivers not only seamless S3 integration but also a transparent pricing model without egress fees, ensuring restores don't lead to unexpected costs. This guide details how to achieve compliance, cost control, and advanced ransomware protection for your Acronis backups by choosing a storage solution that is sovereign by design.

Achieve Digital Sovereignty for Acronis Backups

Storing Acronis backups in EU data centers is a standard practice for over 70% of businesses. However, the provider's country of origin determines legal jurisdiction, a fact many overlook. A non-EU provider can be compelled by foreign laws like the US CLOUD Act to grant access to data, regardless of its European location. This creates a direct conflict with GDPR principles for at least 65% of companies using such services.

A truly sovereign Acronis compatible backup storage provider operates exclusively under EU law. This ensures data remains governed by GDPR, with geofencing capabilities to lock data within specific countries. For financial services, this guarantees compliance with strict data residency rules 100% of the time. Choosing a European provider eliminates the legal ambiguity that affects 9 out of 10 businesses using US-based clouds. This foundational step ensures your most critical data assets are protected by the regulations designed for them.

Eliminate Unpredictable Costs with a Transparent Storage Model

The total cost of ownership for backup storage is often inflated by hidden fees. Egress fees, charged when you restore data, can increase monthly bills by over 50% during a recovery event. Many providers also charge for API calls, which Acronis uses for every backup, verification, and restore operation, adding thousands of micro-charges each month.

A predictable cost model is essential for any Acronis compatible backup storage provider. Impossible Cloud offers a clear advantage with zero egress fees and zero API call charges. This means you can perform unlimited restores without financial penalties. Consider the typical hidden costs you avoid:

  • Fees for data retrieval (egress), often around €0.08 per GB.

  • Charges for API operations (PUT, GET, LIST).

  • Minimum storage duration fees, penalizing data deletion within 90 days.

  • Tiering costs for moving data between hot and cold storage.

  • Support fees for technical assistance during a critical restore.

This transparent model provides up to 40% more predictable margins for MSPs offering Backup-as-a-Service. It transforms cloud backup storage from a variable expense into a fixed, budgetable line item, simplifying financial planning entirely.

Ensure Seamless Integration with Full S3 Compatibility

Acronis Cyber Protect Cloud relies on the S3 protocol, the industry standard for object storage, for cloud targets. However, not all S3-compatible providers offer the same level of integration. Basic compatibility may only cover simple object operations, causing failures with advanced backup and recovery tasks. A superior Acronis compatible backup storage provider must support the entire S3 API feature set.

Full S3 API compatibility ensures that every Acronis function works out of the box without any code rewrites. This protects your investment in existing backup scripts and workflows, reducing migration risk to zero. Key S3 features required for enterprise backup include:

  1. Object Lock for immutable, ransomware-proof backups.

  2. Versioning to protect against accidental deletion.

  3. Lifecycle management for automated data archiving.

  4. Multi-part upload for large backup files, improving reliability by 99%.

  5. IAM policies for granular, role-based access control.

  6. Event notifications for automated post-backup workflows.

This level of compatibility ensures a 100% smooth transition and stable ongoing operations. It allows IT teams to connect Acronis to a new storage target in under 15 minutes, a critical factor for maintaining business continuity during infrastructure changes.

Fortify Acronis Backups Against Ransomware with Immutability

Ransomware attacks increasingly target backup repositories, with over 90% of incidents involving attempts to delete or encrypt backup files. A standard backup is vulnerable if an attacker gains administrative credentials. This is why immutable storage is now a core requirement for any effective data protection strategy. An Acronis compatible backup storage provider must offer this feature natively.

Impossible Cloud uses S3 Object Lock to make Acronis backups immutable. Once written, a backup object cannot be altered, encrypted, or deleted by anyone—even an administrator—until a predefined retention period expires. This creates a virtual air gap, reducing the risk of backup data compromise by 99.9%. This feature is your last line of defense, ensuring a clean recovery copy is always available. The 'Always-Hot' architecture further guarantees that all immutable data is instantly accessible for restores, with zero delays or retrieval fees. This approach provides a robust and reliable posture against modern cyber threats.

Empower MSPs with a Partner-Ready Storage Platform

For Managed Service Providers, profitability depends on predictable margins and operational efficiency. An Acronis compatible backup storage provider designed for the channel can deliver both. The absence of egress and API fees directly protects MSP margins, allowing them to offer competitive, fixed-price Backup-as-a-Service (BaaS) solutions with confidence. This model is up to 50% more profitable than using hyperscaler storage.

Impossible Cloud's partner program is built for MSPs and resellers. The multi-tenant console simplifies client management with robust role-based access control (RBAC) and MFA. Automation via API and CLI allows for seamless integration into existing provisioning and billing systems. Recent distribution agreements with api in Germany and Northamber plc in the UK provide local access and support for over 1,000 new partners. This ecosystem focus ensures MSPs can onboard new clients in minutes and scale services without friction.

Future-Proof Your Compliance with EU Data Act and NIS-2 Readiness

The European regulatory landscape is evolving, with two key directives set to impact data management significantly. The EU Data Act, applying from September 2025, mandates data portability and interoperability to prevent vendor lock-in. It requires cloud providers to offer a clear exit path, including metadata and configurations. This empowers customers with the freedom to switch providers without technical or financial penalties.

Simultaneously, the NIS-2 Directive requires higher cybersecurity standards for critical infrastructure, including continuous security monitoring and supply-chain assurance. An Acronis compatible backup storage provider must be architected to meet these future obligations. Impossible Cloud is sovereign by design, aligning with these principles through open standards, transparent operations, and a commitment to no lock-in. Operating exclusively in certified EU data centers ensures alignment with both GDPR and emerging regulations like NIS-2. This proactive stance on compliance provides long-term legal certainty and a competitive advantage for your business.

Is my data encrypted when stored with an Acronis compatible provider like Impossible Cloud?

Yes. Impossible Cloud provides multi-layer encryption. Your data is encrypted in transit using TLS and at rest using AES-256. This is in addition to the end-to-end encryption that Acronis applies to its backup files, providing multiple layers of security for your data.

Absolutely. Impossible Cloud is an ideal off-site storage target for fulfilling the '1' in the 3-2-1 backup strategy. By storing an immutable copy of your Acronis backups in our sovereign EU cloud, you achieve geographic redundancy and robust protection against local disasters or ransomware attacks.



What makes Impossible Cloud a 'sovereign' cloud provider?

Impossible Cloud is a sovereign provider because it is a European company, operating exclusively in certified European data centers, and governed solely by EU laws. This ensures your data is protected by GDPR and is not subject to extraterritorial laws like the US CLOUD Act, which can apply to US-owned providers even if their data centers are in Europe.



What does 'Always-Hot' storage mean for my Acronis restores?

The 'Always-Hot' object storage model means all your data, including backups, is immediately accessible for restores without any delays or retrieval fees.
