Hi Alexander, thank you for your reply. I understand what you mean and my question is more a request of a new feature in Veeam. It can be normal that the UUID from replica is the same as the original VM when it is running (on behalf of veeam server); but most of the time the replica is down. Simplivity has trouble with non unique UUID in same vCenter, sometime tasks are triggered on replica instead of the original VM. I saw that in hyper-V environment, the administrator can chose to restore a replica with same UUID or not; it was the reason that I decide to post this question/request. In our environment Simplivity, the non unique UUID is a problem.
Thank you in advance for your time, regards, Laurent
