What's your hypervisor manager? Or are you just bare metal?
For VMWare and Proxmox both, I would recommend the community edition of Veeam. It can handle up to 10 VMs for free.
If you've got the funds as a small-to-large business, Veeam's first paid tier, on a yearly basis, is a solid option to backup even more.
Caveat emptor if you buy a license (or not): Veeam runs on Windows only. I have used, like, a single internal network Windows VM dedicated just to Veeam before. It has an easy to pick up UX after a little research, and the UI is clean.
