For Managed Service Providers in 2025, choosing the right S3-compatible object storage for client backups is a critical business decision. Unpredictable costs from hyperscalers can destroy margins overnight, while growing demands for data sovereignty require a new approach to compliance. The best S3 storage for MSP backups must deliver more than just capacity; it needs to provide a predictable economic model, verifiable EU data residency, and robust ransomware protection. This guide outlines a strategy for selecting a storage partner that helps you build a profitable, compliant, and resilient backup service.
Key Takeaways
- The best S3 storage for MSP backups combines EU data sovereignty with a predictable cost model that has zero egress or API fees.
- Immutable backups with S3 Object Lock and an 'Always-Hot' architecture are essential for ransomware protection and fast recovery.
- A partner-ready platform with multi-tenant management, full S3 API compatibility, and proactive regulatory alignment simplifies operations and drives growth.
Prioritize Digital Sovereignty and Predictable Costs
A majority of EU decision-makers now demand European solutions for critical infrastructure, making EU data residency a key criterion. The best S3 storage for MSP backups must be sovereign by design, operating exclusively in certified European data centers. This approach ensures full GDPR compliance and avoids CLOUD Act exposure for your clients. It also builds a foundation of trust for businesses in regulated industries. This commitment to EU-centric governance is a powerful differentiator.
Equally important is a predictable cost model that protects your margins. Our platform eliminates egress fees, API call costs, and minimum storage durations entirely. This transparent economic structure allows you to price your backup-as-a-service offerings with confidence, knowing your costs will not fluctuate unexpectedly. You can find more details in our guide to no-egress-fee storage. This financial predictability is the bedrock of a scalable MSP business.
Deliver Enterprise-Grade Ransomware Protection
Ransomware remains a primary threat, making immutable backups a non-negotiable feature for any MSP offering. Our platform provides S3 Object Lock, a powerful tool for creating write-once-read-many (WORM) storage. This ensures that once backup data is written, it cannot be altered or deleted for a defined retention period. This capability is your clients' last line of defense in a recovery scenario.
Our architecture enhances this protection with an "Always-Hot" object storage model. Unlike complex tiering systems that can cause restore delays and API timeouts, all data is immediately accessible. This approach offers several key benefits for MSPs:
- Guarantees fast, predictable restores during a crisis.
- Reduces operational complexity by eliminating brittle lifecycle policies.
- Ensures third-party backup tools remain stable and performant.
- Strengthens your ability to meet stringent recovery time objectives (RTOs).
This resilient foundation is essential for building ransomware-proof services that clients can depend on.
Streamline Operations with Full S3 Compatibility
The best S3 storage for MSP backups must integrate seamlessly with your existing tools and workflows. Our platform offers full S3 API compatibility, protecting your past investments in scripts, applications, and backup software. This goes beyond basic object operations to include advanced capabilities like versioning, lifecycle management, and event notifications. This ensures your pipelines run without any code rewrites.
This compatibility simplifies migrations and day-to-day management, allowing your team to focus on service delivery instead of troubleshooting. Whether you use Veeam, Acronis, or MSP360, our storage works out-of-the-box. This operational continuity is a core component of an efficient, scalable backup service.

Scale Your Business with a Partner-Ready Platform
A successful backup service requires more than just storage; it needs robust management tools designed for the channel. Our partner console is built for multi-tenant management, featuring granular, role-driven policies (RBAC) and mandatory MFA for enhanced security. You can automate everything from bucket creation to reporting using our comprehensive API and CLI. This reduces manual overhead by over 50%.
We are committed to expanding access for our partners across Europe. Our distribution momentum is growing with key partnerships, including:
- api in Germany, expanding our reach in the DACH region.
- Northamber plc, our first distributor in the United Kingdom.
These partnerships make it easier for resellers and MSPs to onboard quickly and start building profitable services. This partner-centric approach is why we are a leading choice for reseller cloud storage.
Future-Proof Your Services with Proactive Regulatory Alignment
The European regulatory landscape is evolving, creating new obligations for MSPs. Our platform is designed to help you stay ahead of two key regulations. The EU Data Act, applying from September 2025, mandates data portability and interoperability to prevent vendor lock-in. Our use of open standards and a zero-egress fee model aligns perfectly with these requirements, ensuring a real exit path for you and your clients.
Simultaneously, the NIS-2 Directive requires stricter cybersecurity measures and supply-chain assurance from a wider range of entities, including MSPs. Our platform's security features, including multi-layer encryption and immutable storage, are baked into our operations. This proactive compliance simplifies your regulatory burden. By choosing a partner that is already aligned with these future mandates, you turn regulatory readiness into a competitive advantage for your secure MSP backup offerings.
Implement a Resilient Backup Strategy Without Lock-In
A modern backup strategy, like the 3-2-1 rule, requires offsite, immutable copies of data. Our platform provides the ideal offsite target for this framework, ensuring data is secure, sovereign, and always recoverable. An effective exit strategy is a critical, yet often overlooked, component of service design. Our commitment to open standards and data portability preserves your freedom of action and negotiation power for the long term.
When migrating to a new storage provider, a clear plan ensures a smooth transition. Follow these key steps:
- Verify S3 API compatibility with your existing backup software.
- Map current IAM policies to the new provider's RBAC structure.
- Configure bucket policies, including versioning and Object Lock.
- Run a pilot migration with a non-critical dataset.
- Perform a full test restore to validate data integrity and recovery speed.
This structured approach minimizes risk and ensures your clients' data remains protected throughout the migration process.
