@brandon220 I think Proxmox is a great front end for KVM. From what I see in the updates the other day, they are improving their backup server as well. The only type 1 hypervisor I don't like or not a fan of is Hyper-V. I can use it but it needs some tweaks if you don't have it joined to a domain. But there are some good backup products for it. EXI is good but see no point on me paying for it and no point in using the free version as the API's for VM backups are disabled.
