HI: I have a Windows 2008 R2 Server that hosts 3 Hyper-V machines on it.
first question: What version should I have to purchase? Cloudberry Backup Server edition?
The question is because I also need to backup the "host" also.
second question: should I purchase the backup edition and what is the annual maintenance fee for? do I have to add that to the cart also?
You need the VM Edition: https://www.msp360.com/backup/vm.aspx and it will allow you to perform an image backup on the host and back up all the VMs on the server.
