Veeam, I understand the ROI math Veeam has to do on AHV/KVM support.
However, I have math to consider on my side too. I'm currently running 83 hosts of vSphere Enterprise Plus, nearly all Nutanix, and have moved all of our backups to Veeam. We are enthusiastic Veeam customers. That doesn't change the fact that I would be irresponsible not to evaluate AHV for 2017. Nutanix has already proven their reliability to us, and the potential savings moving to AHV are huge. If I have to make the choice between losing Veeam or a six-figure cost savings, Veeam isn't going to win. My evidence is only anecdotal, but conversations with my peers indicate others are taking a hard look at the same numbers.
