Why multi-cloud disaster recovery isn’t optional anymore

Boardrooms across Australia are asking uncomfortable questions: “What happens if Azure fails?” “How do we protect ourselves when our primary cloud provider has an outage?”

These aren’t hypothetical concerns anymore – they’re strategic imperatives driving a fundamental shift in how organisations approach disaster recovery.

The traditional model of relying solely on your primary cloud provider’s built-in backup features is proving inadequate.

As regulatory bodies like APRA scrutinise data protection practices more closely, and as organisations spread their operations across 10-15 different cloud platforms, the need for comprehensive multi-cloud disaster recovery has never been more pressing.

The multi-cloud reality check

Organisations aren’t choosing multi-cloud strategies for the complexity – they’re being forced into them by necessity. Development teams research extensively and select best-of-breed solutions, sometimes spanning nearly 20 providers to handle different aspects of their systems.

The result? A sprawling cloud infrastructure that’s powerful but fragmented from a disaster recovery perspective.

The numbers tell a sobering story. According to the Veeam 2024 Data Protection Trends Report, while 52% of organisations run containers in production (with another 35% in planning phases), only 25% protect their container deployments with purpose-built solutions.

Most administrators simply back up underlying storage or database components, presuming they can reconstruct everything else if needed.

Think about that for a moment. Would you only back up the storage under your hypervisor host? Would you only back up the database from your web application?

Yet this is precisely what’s happening across Australian organisations building complex cloud architectures.

When backup becomes an afterthought

The pattern is depressingly familiar. Organisations migrate data to various SaaS and PaaS platforms, drawn by promises of elasticity and innovation.

Backup? That’s considered after the transition is complete. By then, it’s often too late to implement cost-effective protection strategies.

APRA has taken notice.

Regulatory threats of licence removal are becoming a reality for organisations that can’t adequately protect their data. Sometimes the data literally cannot be backed up because certain cloud providers don’t release APIs, lack plugins, or simply don’t provide the necessary access points for comprehensive protection.

The ‘dump and sweep’ approach—essentially starting from scratch when disaster strikes—becomes the only option. There are no service level agreements in these scenarios.

The best you can hope for is to rebuild everything, knowing that some data and configurations will be permanently lost.

The shared responsibility gap

Cloud providers operate under a shared responsibility model, but many organisations haven’t grasped what this means in practice.

Your DevOps teams might be brilliant at deployment and scaling, but are they considering Grid Security Infrastructure (GSI) requirements? Are they protecting Git repositories and deployment pipelines?

These questions matter because if your code repositories and automated deployment pipelines are compromised, recovery becomes exponentially more complex. Ideally, recovery should be a few commands that rebuild the environment automatically.

Without proper protection of these foundational elements, you’re looking at weeks of manual reconstruction.

The responsibility matrix varies depending on whether you’re dealing with stateful or stateless applications. Stateful applications retain data about client sessions between requests, requiring more comprehensive backup strategies.

Yet according to container backup statistics, responsibilities for protecting these environments are scattered across database admins (27%), storage admins (24%), backup admins (21%), and Kubernetes admins (29%).

This fragmented ownership creates dangerous gaps. When everyone is responsible, often no one is truly accountable.

The true cost of reactive disaster recovery

Planning disaster recovery after implementation is expensive – and frequently sits outside the original project budget because governance and recovery weren’t included from day one.

This reactive approach creates a cascade of problems:

• Budget overruns: Retrofitting comprehensive backup and recovery solutions costs significantly more than building them into the initial architecture.
• Limited options: Once you’re locked into specific cloud architectures, your recovery options become constrained by what those platforms support.
• Compliance violations: Regulatory requirements don’t wait for your recovery strategy to catch up with your cloud adoption.
• Operational complexity: Managing disaster recovery across multiple disconnected systems requires significantly more expertise and resources.

When developers rush into cloud projects, diving into implementation without considering failure scenarios, they create technical debt that organisations will pay for years later.

The feature being available doesn’t mean it’s suitable for business usage – a distinction many teams learn too late.

Building resilient multi-cloud architecture

Effective multi-cloud disaster recovery starts with a simple question: ‘Can this system be recovered?’

This question should be central to every architectural decision from day one, not an afterthought.

Consider implementing these strategies:

• Cross-cloud redundancy: Don’t rely on additional geographic regions from the same provider. True redundancy means having recovery capabilities across different cloud platforms.
• Immutable backups: Ensure your backup copies can’t be altered or deleted, even by compromised administrative accounts.
• Automated orchestration: Recovery procedures should be documented, tested, and automated wherever possible.
• Regular testing: Conduct tabletop exercises and actual failover tests to validate your disaster recovery procedures.
• Comprehensive protection: Backup not just your data, but your infrastructure as code, configuration management, and deployment pipelines.

The goal isn’t just to have copies of your data – it’s to be able to restore full operational capability quickly and reliably when things go wrong.

Moving beyond hope-based disaster recovery

The uncomfortable truth is that many organisations are running on hope rather than genuine disaster recovery strategies.

They hope their primary cloud provider won’t fail. They hope their backup procedures will work when needed. They hope they won’t face the regulatory scrutiny that’s shutting down less prepared competitors.

Hope isn’t a strategy. Multi-cloud disaster recovery, implemented thoughtfully from the beginning of your cloud journey, provides the resilience modern businesses require. It’s not about expecting failure – it’s about being prepared when it inevitably occurs.

Australian organisations face unique challenges, from APRA compliance requirements to the geographic realities of our market.

Those building comprehensive multi-cloud disaster recovery strategies today will be the ones still operating tomorrow when the next major outage hits.
