Backup solutions (like Veeam) cannot access the API to perform hot backups of running virtual machines.
Thankfully, with the 2025 return of the official free ESXi hypervisor, most users no longer need to resort to such measures. The official free edition is robust enough for learning, testing, and running a capable home lab. For those seeking a more complete enterprise feature set, the VMUG Advantage program provides a legal and affordable route.
The following table summarizes the key differences between the viable paths forward for obtaining and using an ESXi license.

Users often turn to these repositories hoping to bypass the 60-day evaluation limit of ESXi. Because GitHub is generally viewed as a safe and trusted website for developers, many mistakenly assume that the assets shared there are safe or somehow sanctioned. 2.
