UK businesses using Commvault face growing pressure from unpredictable cloud costs and complex data sovereignty rules. A new approach to backup storage is required, one that delivers financial predictability and guaranteed compliance. This article outlines a strategy to achieve both without sacrificing performance.

Key Takeaways

Achieve digital sovereignty and GDPR compliance for your Commvault backups by using EU-only, geofenced storage, eliminating exposure to the US CLOUD Act.

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

Leverage 100% S3 API compatibility for seamless Commvault integration and protect backups from ransomware with immutable Object Lock.

For UK IT leaders, managing Commvault backups effectively means balancing cost, compliance, and security—a challenge amplified by shifting data regulations. With the EU's Data Act and NIS-2 directive reshaping data governance, relying on non-EU cloud providers introduces significant risk. This guide details how European-based, S3-compatible object storage provides a modern solution for Commvault users, offering a sovereign, high-performance, and cost-predictable platform built for the regulatory landscape of 2025 and beyond. It’s a direct path to strengthening your data sovereignty in the UK.

Navigate UK and EU Data Regulations with Sovereign Storage

UK businesses must now navigate a dual regulatory framework, complying with both domestic laws and EU mandates like GDPR. Post-Brexit, data sovereignty has become a top strategic priority for over 70% of UK organisations. The EU Data Act, fully enforced from September 2025, introduces strict rules on data portability and prevents vendor lock-in.

For Commvault users, this means the physical location of backup data is more critical than ever. Storing data outside the EU can expose firms to the US CLOUD Act, creating compliance conflicts. Using a European provider with country-level geofencing ensures your Commvault backup data remains under EU legal control. This strategy mitigates 100% of data residency risks.

This approach prepares your organisation for upcoming regulations, including the NIS-2 directive, which demands robust supply-chain security.

Eliminate Unpredictable Costs in Your Commvault Backup Strategy

Cloud egress fees are a major pain point, with some firms spending 10-15% of their total cloud bill on data transfer costs alone. These variable charges make budgeting for Commvault backup and recovery operations nearly impossible. A transparent pricing model is essential for financial control and delivering predictable margins for MSPs.

Impossible Cloud removes these financial barriers entirely with a clear economic model. We offer a superior solution for cloud backup with key financial benefits:

  • Zero Egress Fees: Freely access or restore your Commvault data without penalty charges, saving up to 40% on data transfer.

  • No API Call Costs: Automate and manage your backups without incurring hidden fees for API interactions.

  • No Minimum Storage Duration: Pay only for the storage you use for the time you need it, increasing budget flexibility by at least 25%.

This predictable-by-design model ensures total cost of ownership (TCO) is clear from day one. This financial stability is crucial for long-term planning and scaling your disaster recovery capabilities.

Achieve Seamless Integration with S3-Compatible Architecture

Full S3 API compatibility is non-negotiable for modernising your Commvault storage infrastructure without disruption. It ensures that your existing backup scripts, applications, and workflows continue to operate flawlessly. This compatibility protects your past investments and minimises migration risk to zero.

Our platform guarantees 100% S3 API compatibility, going beyond basic operations to support advanced capabilities. This allows for immediate integration with your Commvault environment. Key features include:

  1. Support for versioning and lifecycle management policies.

  2. Seamless use of your existing API, CLI, and SDK tools.

  3. An “Always-Hot” architecture, ensuring all data is instantly accessible.

  4. Elimination of fragile tiering, which avoids restore delays affecting 94% of firms.

This architecture simplifies operations and ensures consistent, predictable performance for both backup and restore jobs.

Strengthen Ransomware Defence with Immutable Commvault Backups

Ransomware attacks increasingly target backup repositories to prevent recovery, with global damages expected to exceed $30 billion. Immutable storage, or Object Lock, is your strongest defence. It makes your Commvault backup data unchangeable and undeletable for a set period.

This Write-Once-Read-Many (WORM) model guarantees a clean recovery point. Even if primary systems are compromised, your backups remain secure and tamper-proof. This capability is essential for meeting compliance mandates under GDPR and NIS-2, which require verifiable data integrity. Our platform integrates Object Lock seamlessly, providing a critical layer of defence for your Veritas and Commvault storage.

Implementing immutability reduces recovery time by up to 50% and ensures business continuity after an attack.

Empower UK Channel Partners and MSPs

For UK Managed Service Providers, predictable margins are the foundation of a profitable BaaS offering. Our partner-centric model is built for the channel. Through our UK distributor, Northamber plc, we provide local access and support for resellers and MSPs.

Our partner program delivers tangible benefits that directly address MSP pain points. We offer a platform that is truly partner-ready:

  • Predictable Margins: The zero-egress-fee model allows MSPs to build defensible pricing for their Commvault backup services.

  • Multi-Tenant Management: A dedicated console with robust RBAC and MFA simplifies managing multiple clients securely.

  • Full Automation: API and CLI tools enable fast onboarding and integration into existing management platforms.

  • UK Distribution: Our partnership with Northamber plc provides a streamlined procurement and support channel for over 5,000 UK resellers.

This approach helps our partners build competitive and compliant Veeam and Commvault cloud storage solutions.

Implement a Modern Commvault Storage Strategy in 3 Steps

Transitioning to a sovereign and predictable storage solution for Commvault is a straightforward process. A successful migration protects data integrity and minimises downtime. A thorough storage vendor evaluation is the first step.

Here is a simple, three-step plan to modernise your backup infrastructure:

  1. Configure the S3 Target: Add Impossible Cloud as a new S3-compatible storage target in your Commvault Command Center, using the provided endpoint and credentials. This takes less than 10 minutes.

  2. Define Policies and Immutability: Create new backup policies directed at the new storage target. Enable Object Lock (immutability) for a defined retention period to secure data against ransomware.

  3. Test and Verify: Run a test backup and, more importantly, a test restore of a critical workload. Verifying the recovery process ensures 100% confidence in your new setup.
