Ive tried all the main "Homelab Hypervisors" in my lab. VMWare, HyperV, Proxmox, XCP-NG/XenServer. I always come back to proxmox because it offers all of the features I need (HA and Backups primarily) in an extremely easy to use fashion.

I had a great deal of problems getting XCP-NG/XenOrchestra's backup process to function correctly.

Proxmox Backup Server just works. Its the first time in many years of homelabbing/SysAdmin in general where a solution does what its supposed to without needing to contact support.
