Why cloud storage and cloud backup are not the same thing — and why it matters
KEY TAKEAWAYS
Google Cloud protects their infrastructure. They do not protect your data.
45% of all data loss incidents now occur in cloud or SaaS environments — human error, ransomware and misconfigurations are the leading causes.
Even if Google offers its own backup service, that backup sits inside the same system — and under the same US legal jurisdiction — as your production data.
Many organisations that have migrated to Google Cloud feel protected. Google manages the infrastructure, offers availability zones, geo-redundancy and its own Backup & DR service. What could still go wrong?
More than most IT managers expect. Because Google Cloud protects the platform — not what you put on it. The responsibility for your data lies with you, not with Google. This is called the Shared Responsibility Model, and it is the most underestimated agreement in cloud computing.
What does Google Cloud actually protect?
Google guarantees that the GCP platform will be available. Its SLA commits to high uptime for most services. That means the infrastructure — the servers, the network, the storage layer — stays up and running.
What Google does not guarantee is that your data will survive what happens on top of that infrastructure. Google's own Shared Responsibility Model states explicitly that security in the cloud — your data, your configurations, your access management — is the customer's responsibility.
The distinction is simple: Google protects the building. What is inside it is your responsibility.
What can go wrong in Google Cloud?
According to research by Datastackhub, 45% of all data loss incidents now occur in cloud or SaaS environments. These are the main causes:
Human error
Files get deleted. Cloud Storage buckets get overwritten. An administrator accidentally removes the wrong project or IAM binding. Human error accounts for 32% of all data loss incidents globally — and once data is deleted past GCP's retention window, it is permanently gone.
Ransomware
Ransomware increasingly targets cloud environments directly. Cloud ransomware incidents rose 28% year-over-year in 2025, with attackers specifically targeting backup repositories to prevent recovery. A GCP environment without an independent, immutable backup copy has no fallback once encryption takes hold.
Misconfiguration
Misconfiguration is responsible for 68% of all cloud data exposures, according to SentinelOne's 2026 cloud security report. A misconfigured IAM policy, an overly permissive service account, an accidentally public Cloud Storage bucket — these are operational risks that no uptime guarantee protects against.
CLOUD Act: The US Government Can Claim Your Data
This is the risk that surprises most organisations: even if your data never leaves Europe, it may not be under European law. Google is a US company. Under the US CLOUD Act, passed in 2018, US authorities can compel Google to hand over data stored anywhere in the world — including servers in europe-west3 (Frankfurt) or europe-west4 (Netherlands) — without notifying the data subjects or European supervisory authorities. Your data is in Google Cloud. Google Cloud is in the EU. But Google is in the US. Under the CLOUD Act, jurisdiction follows the company — not the server.
But Google offers its own backup service — isn't that enough?
Google does offer a backup service: Google Cloud Backup & DR, for Compute Engine, Cloud SQL, GKE and more. For operational scenarios — restoring a snapshot, recovering a database — this works well.
The problem is structural: Google Backup & DR sits inside the same GCP project, under the same IAM credentials, as your production data. Your backup vault, your production environment and your administrators share the same perimeter. A single compromised service account or Org Admin role is enough to reach both.
And critically: Google Backup & DR is still operated by a US company. A backup stored inside GCP is subject to exactly the same CLOUD Act jurisdiction as the data it protects.
An independent sovereign backup — operated by a European entity, outside the GCP perimeter, with its own identity plane — remains accessible and legally protected even when your Google Cloud environment is not.

What is data sovereignty — and why does it matter for Google Cloud?
Data sovereignty, as defined by ENISA, is the ability of an organisation or jurisdiction to control how its data is stored, processed and accessed — including protection from foreign legal frameworks.
It is different from data residency. Data residency tells you where the data is stored. Data sovereignty tells you who controls access to it — and who can legally demand it.
A company whose GCP data sits in the Netherlands but is managed by a US company has data residency in the EU. It does not have data sovereignty. The CLOUD Act can reach across the Atlantic regardless of where the servers are physically located.
For organisations subject to DORA, NIS2 or sector regulators such as AFM or BaFin, data sovereignty is not a preference — it is increasingly an audit requirement.
Mindtime's sovereign backup for Google Cloud is is designed to meet this standard: EU legal entity, EU-operated data centres, customer-held encryption keys and an identity plane fully independent of Google Cloud IAM.
For Whom Is This Most Urgent?
Financial services
under DORA, which requires demonstrable operational resilience and independent recovery capabilities outside a single provider's control plane.
Healthcare organizations
processing patient data under GDPR, where a US government data request — however unlikely — can constitute a reportable breach with significant regulatory consequences.
Public sector and critical infrastructure
subject to NIS2, which requires supply chain risk management. A cloud backup held by a US-parented provider is a supply chain dependency that NIS2 auditors flag.
Any organization whose CISO or DPO has been asked:
"If our GCP environment is compromised, or if a foreign government requests our data, what is our recovery plan?"

Conclusion
Using Google Cloud is a smart decision. Assuming Google Cloud protects your data is not.
Google protects infrastructure. It does not protect you against human error, ransomware, misconfiguration or legal access requests from a foreign government. And when Google offers its own backup service, that backup sits inside the same platform — the same jurisdiction, the same IAM credentials — as the data you are trying to protect.
Sovereign backup is not about distrusting Google. It is about completing your recovery strategy with a copy that is genuinely independent: a different operator, a different legal jurisdiction, a different identity plane.
