In many homelab and production environments, PMG runs as a virtual machine on Proxmox VE, VMware ESXi, Hyper-V, or another hypervisor. Bare-metal installation is also supported. In this video, I demonstrate the installer storage options and verify the resulting filesystem and ZFS pool configuration after each installation. Proxmox documents that PMG backups can include the complete /etc/pmg/ configuration, mail-filter rules, and the statistics database. It also supports configuring a PBS remote for direct backups, restores, and scheduled backup jobs.
