Win11 is a better daily driver than any Linux system. (If it was different, I’d probly start hating Linux too.) Win11 HyperV is a well developed virtualization system. Run a VM if you need Linux. There’s also the M$ linux-on-windows thing, but I don’t enjoy having the OS and the guest mix like that, so a VM is best for me.

Proxmox is Debian, so much of your ideas could translate directly across. That said, I try to mod the PVE server as liitle as possible.

Proxmox makes it so easy to spin up yet another VM or LCX to handle services with its core offerings. Also google “proxmox helper scripts” to find tteck’s additional stash of ready-made LCX.

Boy. You asked about Proxmox. Nobody said anything.

How does Proxmox make it easier? Have you used it? All sorts of ways. Like, its a full virtual infrastructure management system instead of just an OS. Proxmox loves ZFS. It does many of the things you’ve mentioned here.

Proxmox does have its own backup system that can work with an NFS target or with their smart dedupe storage and replication server product. https://www.proxmox.com/en/products/proxmox-backup-server/overview

You’ve got some pretty advanced ideas and perhaps have already moved beyond the Proxmox question. But if you are curious and haven’t used it, spin up a server and give it a whirl.
