Data sovereignty has become a key buying criterion in Europe and beyond, but some platforms still treat it as a compliance checkbox rather than an architectural position.
That’s a high-risk approach—and misses out on the opportunity for MSPs to use backup as a route to growth.
Part of the problem is that production environments tend to be well secured and well understood. But backups are where sovereignty can quietly break down, because they rarely receive the same scrutiny as live systems.
Here’s a practical guide to help MSPs understand data sovereignty, its backup implications, and how sovereign backup can unlock growth.
Sovereignty Is Now a Buying Criterion, Not a Nice-to-Have
Across the public sector, finance, healthcare, and critical infrastructure, customers are increasingly asking pointed questions before they’ll sign: where exactly does our data live, who controls the encryption keys, and can you prove it on demand?
Changes to the regulatory backdrop are driving new expectations:
- GDPR sets strict rules on how personal data is stored, processed, and transferred—and backup copies are fully in scope, not a gray area.
- NIS2 forces essential and important entities to demonstrate they can withstand and recover from cyber incidents.
- DORA requires financial institutions to maintain operational resilience, including sovereign, tested, and auditable backup and recovery processes.
- The EU Cloud Certification Scheme introduces sovereignty tiers that determine whether a Cloud service qualifies as “EU-sovereign”, directly shaping backup provider selection.
Hosted in the EU Doesn’t Mean Sovereign
Some businesses mistakenly assume “hosted in the EU” necessarily means “sovereign”. That is not the case.
A service can run entirely out of a data center in Frankfurt and still be subject to a foreign jurisdiction, because legal control follows the company, not the data center. If a provider is headquartered outside the EU, its EU-hosted infrastructure can still be reachable through that provider’s home jurisdiction’s legal process.
Schrems II is the reference point here—this EU ruling means backup data stored in or merely accessible from the US could be (or soon become) non-compliant. The fine exposure comes from GDPR enforcement, not from Schrems II itself: GDPR Article 83 sets penalties of up to €20 million or 4% of global annual turnover for violations of this kind.
Encryption key ownership, not physical storage location, is often the real sovereignty line. If a US entity controls the keys, the data is unlikely to be EU sovereign, even if it’s stored in Europe.
Why Backups Are the Blind Spot
Production data usually gets the compliance attention. Backup workflows lag for a few structural reasons:
- They’re automated, so nobody reviews every replication job to see where it lands.
- They’re often inherited—built on tooling and defaults chosen years before sovereignty became a board-level topic.
- They frequently depend on non-EU services for logging, key management, or orchestration, without anyone flagging it.
The most common failure modes are cross-border replication that happens silently, key management that sits outside the EU by default, and metadata storage nobody thought to check. None of these show up as a single dramatic incident—but they could completely derail an audit or client onboarding.
Restore location matters just as much as backup location. Restoring into a non-EU region during an incident can itself constitute a compliance breach, which means disaster recovery paths need to be sovereign by design.
What Sovereign-by-Design Actually Looks Like
Sovereignty works best as a set of concrete architectural commitments rather than a marketing claim:
- EU-only storage and replication — every backup copy stays within EU borders, eliminating cross-border transfer risk.
- Customer-controlled encryption keys — when the customer holds the keys, a foreign jurisdiction can’t compel access, regardless of where the bytes sit.
- Transparent data-location reporting — showing customers exactly where their backup data lives, which also makes audits far less painful.
- Sovereign DR paths — disaster recovery has to restore into EU-only environments, or the DR event itself becomes the violation.
- Local deletion guarantees — GDPR’s right to erasure applies to backups too, so systems need verifiable deletion without weakening resilience.
On the infrastructure side, useful patterns include EU-only object storage tiers, region-locked snapshots that can’t accidentally replicate into non-EU zones, sovereign key vaults operated under EU law, and multi-cloud sovereign designs that spread resilience across EU-sovereign providers without introducing jurisdictional creep.
Sovereignty drift—the slow, unnoticed shift of workflows back into non-EU territory—is a real risk, and a reason to build in regular audits and automated checks rather than treating sovereignty as a one-time migration project.
The Business Case, Not Just the Compliance Case
Sovereignty compliance in backup is a competitive lever. Here’s what that looks like in practice, across a handful of illustrative MSP and CSP scenarios:
- A German MSP won multiple public sector tenders by offering fully EU-sovereign backup tiers with transparent data-location reporting.
- A fintech firm hit its DORA compliance requirements by implementing EU-only disaster recovery paths and customer-controlled encryption keys.
- A healthcare provider avoided GDPR breaches by eliminating non-EU replication from its backup workflows entirely.
- A SaaS vendor increased enterprise adoption by actively marketing its EU-sovereign backup and recovery architecture as a selling point.
The pattern across all four is that sovereignty didn’t just reduce risk; it opened doors. MSPs and CSPs (and their customers) that can guarantee EU-only data handling are standing out in a crowded market and winning public sector and enterprise deals that sovereignty-agnostic competitors simply can’t bid on.
Practical Steps MSPs Can Take Now
Getting to grips with backup data sovereignty can feel overwhelming, but here are actions that can be completed in a few months:
- Map every backup data flow. Know where every copy, snapshot, and metadata record actually lives before making any other decision.
- Identify non-EU dependencies. Many backup systems quietly rely on non-EU services for logging, key management, or orchestration—find them.
- Move to EU-only storage and key management. Migrating to EU-sovereign storage and EU-controlled key vaults closes the biggest gaps in one move.
- Implement sovereignty monitoring. Automated checks stop backup data from drifting into non-EU regions or services over time.
- Offer sovereignty-tiered services. Creating EU-only backup tiers gives customers a real choice and positions the provider as sovereignty-ready.
The underlying message for MSPs is that sovereignty isn’t something to bolt on after the fact. It should be an architectural starting point—and the providers who treat it that way now will be the ones who can say yes to the RFPs that increasingly require it.
Huge thanks to Comet Backup for their expertise and support in creating this article. Here’s some more about what they do:
Comet Backup understands the importance of delivering the data sovereignty that modern MSPs and their customers demand. Its Self-Hosted deployment option gives MSPs full control over exactly where their console and backup data reside, its zero-knowledge encryption model means customers hold their own keys by default, and its support for S3 Object Lock lets MSPs build immutable, EU-resident backup tiers on the storage of their choice.
