Acronis True Image Virtual Edition has the same GUI and functionality as Acronis True Image Echo Enterprise Server; the licensing policy is different
Acronis True Image Virtual Edition is absolutely the same in GUI and functionality as Acronis True Image Echo Enterprise Server with Acronis Universal Restore.
The differences between Acronis True Image Virtual Edition and Acronis True Image Echo Enterprise Server is in licensing:
(!) The virtual machines must be hosted on the same licensed physical machine.
Fast facts
If there is a cluster environment running a virtual machine (e.g. ESX cluster), then you need to have a separate license for each physical node that you are going to back up. If you are going to back up only a virtual machine composed of several nodes, then you still need a separate license for each physical node.
You can back up virtual machines by either installing Acronis Agents inside each of them, or by integrating them with ESX (see Backing Up a Virtual Machine with Acronis True Image Echo and VMware Consolidated Backup).
