Geographic Redundancy
Geographic redundancy means keeping copies of your data, and sometimes whole systems, in more than one physical location. If a fire, flood or regional outage takes out one site, the other carries on.
This article explains why distance matters and how much redundancy is sensible for a typical business.
Why Location Matters
Two copies in the same building share the same risks. Genuine redundancy puts copies far enough apart that one disaster cannot affect both.
- Survives local disasters such as fire or flooding.
- Survives a whole data-centre or region going offline.
- Keeps service available to users elsewhere.
How Much Is Enough
For most businesses, backups held in a second region are plenty. Systems that must never go down may run live in multiple regions at once, which costs more.
The Trade-Off to Weigh
More geographic spread means more resilience but also more cost and complexity, and sometimes slower data transfer between distant locations. We help you decide how far to go by weighing the cost of an outage against the cost of the redundancy that would prevent it.
| Level | Protects against | Cost |
|---|---|---|
| Single location | Little | Lowest |
| Second region backup | Local & regional loss | Medium |
| Multi-region live | Almost everything | High |
