AWS Elastic Disaster Recovery
#231 · Level 4 · Operations and specialized areas · Migration and transferConcept
Section titled “Concept”AWS Elastic Disaster Recovery keeps a continuous copy of your servers in AWS, so that in a disaster they can be started in AWS within minutes. Disaster recovery (DR) means a plan to keep the business running even after a major disaster. When you install an agent on the main server, its data is continuously copied to a low-cost staging area in AWS. In a disaster, full servers are started in AWS from that copy, even from the state at a specific earlier point in time. Once the problem is fixed, you can go back to the original location (failback).
