You have to follow the implementation Guide:

https://helpcenter.veeam.com/docs/van/userguide/deployment.html?ver=21

you can control and deploy the Nutanix AHV Proxy from the VBR Server. 
 

you can do it manually. But I don‘t recommend it todo that.

Manually would require multiple steps:

1. configure backup repo on the vbr and configure a user account to access it
2. add the vbr to the nutanix ahv proxy in the webgui
3. create the backup job and target it to the backup repo

It works now, I didn’t do anything . haha

I think time need to appear normal backup job

As they say about Veeam "It just works".
