If you are managing a SharePoint or Dynamics AX deployment, you can use ASR to eliminate the cost and overhead of maintaining a stand-by deployment for DR or DevTest. ASR can replicate the entire farm and bring it up on-demand for disaster recovery or for creating a production-like test copy. Any new application or configuration changes deployed on the primary farm will be automatically replicated within minutes so you do not have to invest in complex processes to keep the secondary farm up to date.
