Disaster Recovery Sites
i need several popeyes locations in the hood in case one gets shut down
A Disaster Recovery Plan (DRP) describes the steps an organization takes to restore a system or site to a working state. Disasters span anything from a power loss, minor component failure, human-made or natural disasters, like fires, earthquakes or terrorism.
Site Resiliency
Redundant devices and working spares allow quick swapping if systems fail. Enterprise-level networks often have spare sites that provide similar service to the main site. Systems failure or a disaster will cause dependent services to switch over to the alternate site.
There are three levels of site resiliency: hot, warm, or cold.
- Hot sites can failover immediately. It remains on standby, ready to deploy.
- Warm sites are the same as hot sites, except the latest dataset will need to be loaded.
- Cold sites are empty sites that take longer to setup, since we need to install the necessary equipment.
But what if we're broke? Well, we can BUY a backup site from a service provider! What if the disaster is too big? Well, we'll team up with our competitors to restore the service to our customers.
