The only way I see myself ever giving it another go is if I manage to get into my NixOS setup for easy replication or something, too much manual tweaking otherwise.
The compromise I arrived at after I migrated to Linux was booting windows off a VHD file on a USB SSD when I really need it. That way I get a portable, fully performant install without it wasting any disk space or messing with my partitions.
Maybe consider a Hetzner storage box. They support borg, restic, rsync and probably more, there’s no ingress or egress fees and you get unlimited traffic. Very nice for off-site backups if, like myself, you’re on a limited budget.
