Disaster Recovery Across Regions
Disaster recovery is your plan for the rare but serious event — a whole data centre or region becoming unavailable. Spreading critical systems across regions means a major failure in one place need not take your business offline.
This article explains the principles in business terms.
Two Key Numbers
- Recovery time: how quickly you need to be back up after a disaster.
- Recovery point: how much recent data you can afford to lose, if any.
Matching Cost to Need
Tighter targets cost more, because they require more standby capacity ready to take over. We help you decide how much resilience each system truly needs, rather than paying for instant failover everywhere when it is not warranted.
Common Approaches
- Backup and restore: cheapest, slowest to recover.
- Warm standby: a scaled-down copy ready to grow.
- Active-active: full capacity in two regions at once.
Frequently Asked Questions
Isn't the cloud already resilient?
Within a region, yes. Region-wide failures are rare but real, and a cross-region plan protects against them.
