Disaster recovery you can actually trust
Everyone has backups. Far fewer have recovery. The gap between the two is where businesses quietly fail on their worst day.
Two numbers define your plan
- RPO โ recovery point objective: how much data can you afford to lose? This sets how often you replicate.
- RTO โ recovery time objective: how long can you afford to be down? This sets how you architect failover.
Every disaster-recovery decision flows from honest answers to those two questions. A system that can lose an hour of data and be down for a day is far cheaper than one that can lose neither โ so decide deliberately, per system.
The step everyone skips
Test the restore. Regularly, and for real. A backup that has never been restored is an untested assumption, and disasters are a terrible time to discover your assumptions were wrong.
The uncomfortable truth: most recovery plans fail not because backups were missing, but because nobody had ever practised bringing the system back. Rehearse it like a fire drill.
Resilience is not the absence of failure. It is the ability to recover from it faster than it hurts.
