UK organisations using Rubrik face growing pressure from unpredictable cloud costs and complex data sovereignty rules. A misstep in your backup storage strategy can lead to spiralling expenses and significant compliance risks.

Key Takeaways

Achieve UK GDPR compliance and data sovereignty for Rubrik backups by storing data exclusively in geofenced, EU-based data centres.

Eliminate unpredictable cloud costs with a storage model that has zero egress fees, no API call charges, and no minimum storage durations.

Enhance ransomware protection by integrating Rubrik with immutable S3 Object Lock storage, ensuring your backup data cannot be altered or deleted.

For UK IT leaders, selecting the right cloud object storage for Rubrik is a critical decision with long-term consequences. The challenge involves balancing performance and scalability with the stringent demands of UK GDPR and the ever-present threat of ransomware. Many cloud options introduce unpredictable costs through egress fees and API call charges, creating vendor lock-in and budget overruns. This article outlines a strategic approach to Rubrik storage in the UK, focusing on a sovereign-by-design platform that delivers cost predictability, robust security through immutability, and seamless S3 compatibility, ensuring your data remains secure, compliant, and always accessible within European data centres.

Meet UK Data Sovereignty and GDPR Mandates

Organisations in the United Kingdom must ensure their Rubrik backup data adheres to strict UK GDPR and data sovereignty laws. Storing data with non-EU providers can expose it to foreign jurisdictions, such as the US CLOUD Act, creating significant compliance gaps. Our platform guarantees that 100% of your data is stored within certified European data centres.

We provide country-level geofencing to enforce data residency, a key requirement for regulated industries like finance and healthcare. This ensures your Rubrik archives are sovereign by design, aligning with the ICO's requirements for data controllers. Learn more about our approach to data sovereignty in the UK.

This focus on EU legal certainty removes the ambiguity of cross-border data transfers, which is a growing concern for over 60% of businesses. This prepares your infrastructure for evolving regulations.

Eliminate Unpredictable Costs from Your Storage Budget

A major challenge with hyperscale clouds is unpredictable billing, with egress fees and API call charges causing budget variances of up to 30% for many firms. We eliminate these costs entirely for your Rubrik storage. Our transparent pricing model has zero egress fees, no API call costs, and no minimum storage durations.

This predictability empowers Managed Service Providers (MSPs) and enterprises to forecast expenses with 100% accuracy. You only pay for the storage you actually use, simplifying budget management for cloud backup. This model directly addresses the market's demand for cost transparency, a factor driving over 50% of switching decisions.

Here is how this model benefits your Rubrik deployment:

  • Predictable Margins for MSPs: Build BaaS offerings on a fixed-cost foundation.

  • No Bill Shock: Restore data from your Rubrik backups as often as needed without penalty.

  • Simplified TCO: Calculate your total cost of ownership with just one variable.

  • No Data Lock-In: Move your data freely without facing financial barriers.

This economic clarity reduces financial risk and strengthens your negotiating power.

Strengthen Ransomware Defence with Immutable Backups

Ransomware attacks now occur every 11 seconds, making immutable storage a non-negotiable layer of defence. Our platform integrates with Rubrik using S3 Object Lock, making your backup data unchangeable and undeletable for a defined period. This provides a clean, guaranteed-recoverable copy of your data.

This feature is a core component of a modern 3-2-1 backup strategy, where at least one copy is immutable. Immutable backups render ransomware attacks on your archive ineffective, as encrypted production data can be restored from the secure, unaltered copy. This capability is critical for effective disaster recovery planning.

Implementing Object Lock with your Rubrik storage helps meet stringent compliance requirements for data integrity and retention. This proactive security posture is essential for protecting against the average seven-figure cost of a data breach.

Ensure Seamless Integration with Full S3 Compatibility

True S3 compatibility is more than just basic object operations; it is about protecting your existing investments in tools and workflows. Our platform offers a fully S3-API compatible endpoint, ensuring your Rubrik appliances connect and operate without any code rewrites or complex configuration. This protects your investment in tools like Veeam and other solutions.

This seamless integration allows you to leverage Rubrik's powerful data management features while benefiting from a sovereign and cost-predictable storage backend. Your existing scripts, applications, and backup jobs continue to work out-of-the-box, minimising migration risk and operational disruption for your team.

Follow these steps for a smooth transition:

  1. Configure the Endpoint: Point your Rubrik SLA Domain to our S3-compatible service endpoint.

  2. Set Credentials: Create and assign secure IAM credentials for the Rubrik appliance.

  3. Apply Policies: Use Rubrik's policy engine to manage backup, replication, and archival.

  4. Enable Immutability: Activate Object Lock in the storage policy for ransomware protection.

This straightforward process ensures your Rubrik storage is operational within minutes, not weeks.

Leverage an "Always-Hot" Architecture for Instant Recovery

Complex storage tiering introduces delays and hidden costs, especially during an urgent recovery scenario. Our "Always-Hot" object storage model ensures every byte of your Rubrik backup data is immediately accessible, with no restore delays or fees for retrieving data from a cold tier. This simplifies operations and guarantees predictable performance.

An always-hot architecture eliminates the risk of API timeouts and lifecycle policy failures that can compromise restores. This model provides consistent, low-latency access to your entire archive, which is critical when recovery time objectives (RTOs) are measured in minutes. A proper storage vendor evaluation should prioritise this.

This approach avoids the operational complexity of managing different storage classes, reducing the administrative overhead on your IT team by an estimated 15%. Your Rubrik solution benefits from a resilient, high-performance foundation.

Empower UK Channel Partners and MSPs

We are committed to the UK channel, providing MSPs, resellers, and system integrators with a platform designed for profitability and ease of management. Through our UK distributor, Northamber plc, partners gain local access to a predictable and sovereign storage solution. This is similar to how other vendors like Cohesity work with partners.

Our partner-ready console includes multi-tenant management, role-based access control (RBAC), and detailed reporting. The zero-egress-fee model allows partners to build services with defensible, predictable margins, a key differentiator in a competitive market. Automation via a full-featured API and CLI enables fast onboarding and integration into existing service catalogues.

This channel-first approach provides the tools needed to deliver high-value data protection services across the UK.

Future-Proof Your Strategy with Advanced EU Compliance

The regulatory landscape is constantly evolving, and your storage infrastructure must keep pace. Our platform is built to align with upcoming EU regulations like the NIS-2 Directive and the EU Data Act, which will become fully applicable from September 2025. These regulations mandate greater data portability and supply-chain security.

The EU Data Act's focus on removing switching barriers and egress fees is already built into our core business model. Choosing our platform means you are already compliant with the next wave of data regulation, avoiding future lock-in and ensuring long-term freedom of action. This proactive stance on compliance provides a distinct competitive advantage for your business.

This readiness for future rules ensures your Rubrik storage strategy remains resilient for years to come.
