TL;DR Restore a full root filesystem of a backed up Proxmox node - use case with ZFS as an example, but can be appropriately adjusted for other systems. Approach without obscure tools. Simple tar, sgdisk and chroot. A follow-up to the previous post on backing up the entire root filesystem offline from a rescue boot.
ORIGINAL POST Restore entire host from backup
TL;DR Access PVE host root filesystem when booting off Proxmox installer ISO. A non-intuitive case of ZFS install not supported by regular Live Debian. Fast full host backup (no guests) demonstration resulting in 1G archive that is sent out over SSH. This will allow for flexible redeployment in a follow-up guide. No proprietary products involved, just regular Debian tooling.
