Multicloud improves flexibility, but it does not protect your data or guarantee recovery after loss.
Many organisations are moving towards multicloud setups with confidence. The reasoning seems sound: if one cloud provider fails, another keeps services running. This creates a perception of resilience that feels like protection.
But recent large-scale outages have exposed a different reality. When major cloud platforms experience disruptions, shared components — identity services, APIs, and network dependencies — can fail across multiple environments simultaneously. Multicloud does not eliminate this risk.
The core misconception is straightforward: multicloud improves availability in some scenarios, but it does not protect your data. It does not prevent deletion, corruption or ransomware. And it does not replace a structured backup strategy.
Key Takeaways
• Multicloud distributes workloads but does not create isolated, recoverable copies of data
• Outages, ransomware, and accidental deletion can affect all connected cloud environments at once
• Backup and recovery remain essential for business continuity and regulatory compliance
What Does Multicloud Actually Solve
Multicloud is primarily a strategy for flexibility and vendor independence. Organisations use multiple providers to avoid lock-in, distribute workloads, and maintain negotiating leverage.
In practice, it can help with workload distribution across regions, improved uptime for certain applications, and reduced dependency on a single vendor.
Where multicloud helps
If one provider experiences a regional outage, workloads can sometimes shift to another environment. For availability, this is genuinely useful.
Where multicloud does not help
Multicloud does not automatically replicate or version your data. If data is deleted, corrupted, or encrypted by ransomware, that problem does not stay in one environment — it spreads. Without isolated backups, there is nothing to restore.
Why Multicloud Does Not Protect Your Data
Data protection requires three things that multicloud setups do not provide by default: versioning, isolation, and controlled recovery.
Common risks in multicloud environments include:
• Synchronised data corruption across connected platforms
• Accidental deletion replicated instantly across systems
• Ransomware encryption spreading through integrated environments
• No point-in-time recovery without a dedicated backup layer
When your systems sync data between clouds, errors replicate at the same speed as your data. A dedicated solution such as backup as a Service ensures data is stored in a separate, isolated environment and can be restored independently of the production infrastructure.
What Happens During a Large Cloud Outage?
Large outages consistently show that dependencies are underestimated — even in multicloud setups. Shared components are the most common failure point.
These include identity and access management services, APIs connecting cloud platforms, third-party integrations, and shared network infrastructure. When one of these fails, it can take down services across multiple providers at once.
Real impact on organisations
When access is lost, teams cannot retrieve data or continue operations. Finance, support, and core business processes stop. Even organisations using two or three cloud providers often discover they still depend on one provider for critical data storage or authentication.
According to
ENISA’s guidance on cloud resilience
, organisations must ensure independent recovery capabilities rather than relying solely on provider availability. This is a compliance requirement, not just a best practice.
Do You Still Need Backup in a Multicloud Setup?
Yes — and this is not a technicality. Backup solves a fundamentally different problem than multicloud.
Multicloud focuses on availability: keeping services running when one provider has problems.
Backup focuses on recoverability: restoring data after it has been lost, corrupted, or destroyed.
A proper backup strategy provides isolated copies of data, version history for point-in-time recovery, and fast restoration after incidents. A structured
disaster recovery strategy
ensures systems and data can be restored within defined timeframes, regardless of where the failure occurs.
Without backup, multicloud environments still face permanent data loss, extended recovery times measured in days rather than hours, and compliance failures under frameworks such as NIS2.
How to Build a Resilient Data Strategy
Organisations need to combine multicloud with proper data protection. These two approaches are complementary, not interchangeable.
Key elements of a resilient strategy
• Independent backups stored outside production cloud environments
• Clear recovery objectives: defined RTO (Recovery Time Objective) and RPO (Recovery Point Objective)
• Regular recovery testing — not just backup verification, but actual restore tests
• Endpoint protection for user devices outside central cloud systems
Practical approach
1. Identify critical data and the systems that depend on it
2. Implement isolated backups in a separate environment
3. Define and document recovery processes per system
4. Test recovery quarterly and after any major infrastructure change
For endpoint data, endpoint backup ensures that user devices remain protected and recoverable even when central systems fail. The European Commission’s NIS2 Directive requires organisations to demonstrate recovery capabilities — going beyond availability to include proven restoration processes.
Conclusion
Multicloud is a sound strategy for flexibility and vendor independence. But it is not a backup strategy. It does not protect your data from loss, corruption, or ransomware, and it does not guarantee recovery when something goes wrong.
Organisations that rely on multicloud alone often discover too late that resilience and recoverability are not the same thing. A backup strategy remains essential — for operations, for compliance, and for the confidence that recovery is actually possible when you need it.
Frequently asked questions
What is the difference between multicloud and backup? +
Multicloud spreads workloads and services across multiple cloud providers to improve availability and reduce vendor dependency. Backup creates isolated, versioned copies of data that can be restored after loss, corruption, or attack. They address different risks and operate at different layers of your infrastructure. Using multicloud without backup means you have improved uptime but no guaranteed recovery path. Both are necessary for a complete resilience strategy.
Can multicloud prevent data loss from ransomware or accidental deletion? +
No. Multicloud environments synchronise data across connected platforms, which means that ransomware encryption or accidental deletion can replicate across all environments almost instantly. Without isolated backups, there is no clean copy to restore from. Multicloud improves the availability of your services, but it has no mechanism to isolate or version data independently. Only a dedicated backup solution provides the recovery capability needed after data loss events.
Why is backup still required for compliance under NIS2? +
NIS2 requires organisations to demonstrate recovery capabilities — not just that systems stay online, but that data can be restored within defined timeframes after an incident. Multicloud can show that services remained available, but it cannot produce evidence of a successful data restore. Backup provides the audit trail, restore logs, and documented RTO/RPO that regulators expect. Without it, organisations risk non-compliance even if their systems never went fully offline.
