Do I need a Hyper-V agent license to restore?

We're planning to deploy Backup Exec to our enviroment, we've 2 Hyper-V server (Server A and B) which will replicate VM guest each other. We're going to purchase 1 backup server license and 1 Hyper-V agent license to backup the one of Hyper-V server (Server A) and active VM guest.

I'd like to know that, if the Hyper-V server (Server A) is down, can I restore the backedup VM guest to another Hyper-V server (Server B) with only 1 hyper-v agent license?
