I'm sure many have asked this before, but I wasn't able to find a thread that had recent answers to this question, so I'll ask it.
What is a decent free backup software for Windows Server 2016 that works on VMs running on the free ESXi hypervisor?
I have 6 training VMs running Windows Server 2016: DC, WSUS, file server, PostGreSQL, SQL Server Express 2017, and an IIS web server, spread across 4 SSDs with no redundancy. I've spent a lot of time on them, and I'd prefer to not lose them. So, I need backups. Currently, they're all running the built in backup program to extra virtual drives stored on 1TB mechanical hard drives, but that seems a little less than a preferred backup method.
Any recommendations by those who have actually used them and liked them (don't just send me stuff from a google search, I have done that myself, and many of those aren't very good) would be greatly appreciated.
Have you already checked the free edition of Veeam?

I looked at Veeam, but the last time I downloaded their free version back in 2013, I was inundated with sales calls for almost a year. I'd rather avoid that, but I'll do it if I have to.
