Nobody likes thinking about disasters. But the question isn't whether something will go wrong—it's when, and whether you'll be ready. Ransomware, hardware failure, natural disasters, human error—threats are varied and real.
What Disaster Recovery Means
Disaster recovery (DR) is your ability to restore business operations after a serious disruption. It's not just backups—it's the complete capability to get systems running again.
Key concepts:
- RTO (Recovery Time Objective): How quickly you need to be back up
- RPO (Recovery Point Objective): How much data you can afford to lose
- Recovery procedures: The actual steps to restore operations
Traditional DR Challenges
Traditional disaster recovery required duplicate infrastructure—backup servers, a secondary site, replication technology. Expensive and complex. Many small and medium businesses couldn't afford proper DR.
How Cloud Changes DR
Cloud makes DR more accessible:
No upfront hardware: You don't need to buy duplicate servers. You pay for recovery infrastructure when you need it.
Geographic distribution: Cloud providers have data centres across regions. Your recovery site can be in a different geographic zone automatically.
Automated backups: Cloud platforms offer built-in backup services with configurable retention and replication.
Faster recovery: Spinning up replacement infrastructure in the cloud takes minutes, not days.
What You Still Need to Do
Cloud enables DR, but doesn't do it for you:
- Define your RTO and RPO requirements
- Configure backups and replication properly
- Document recovery procedures
- Test recovery regularly (this is where most plans fail)
- Keep procedures updated as systems change
Testing Is Not Optional
A recovery plan that's never been tested is a hope, not a plan. Test regularly:
- Can you actually restore from backup?
- How long does recovery actually take?
- Do people know their roles?
- What breaks that you didn't expect?
Getting Started
If you don't have DR today:
- Identify your most critical systems
- Define acceptable RTO and RPO for each
- Implement cloud backup with appropriate settings
- Document basic recovery steps
- Schedule and perform a test recovery
Start simple. Something is infinitely better than nothing.
