Thank you for sharing your feedback!
Keep in mind that VEB is designed to work on the guest level of the operating system, so its recommended to install it inside the VM. If you want to create an backup outside the OS on a hypervisor level – the best approach would be to use our flagship product - Veeam Backup and Replication
(it fully supports Hyper V and you can try the free edition first)
Is there coming possibility to run backups directly from boot media?
We got this feature request on our radar. Thanks.
