Until today, I was using the free version of ESXi. But now, I want to make backup of my VMs using Veeam Backup and Replication Free Edition.
Actually, I have only one host ESXi, but I will not take the Essential kit of vSphere because my installation could use more than 3 hosts in the future. I would like to get vSphere Standard license for my host, but I wanted to know if it is mandatory to take the vSphere vCenter Server license. Today, I use vSphere client to manage my ESXi, so I would like to keep this tool.
