You need to create an ever-running SureBackup job with the application in question, and provide a convenient DNS name for it.
- Create a new application group with VMs running the required application and its dependencies.
- Create a new SureBackup job and select "Keep application group running", then schedule it to run after each backup.
- Open settings for Virtual Lab used by SureBackup job, and edit static IP mapping feature to map isolated IP address of required VM to some unused IP address in the production network.
- Update production DNS and assign simple DNS name to the IP address chosen earlier. For example, "exchange-yesterday."
