KVM (RHV, OLVM, Proxmox) • Backup Proxmox OS on RAID1 ZFS

Hi, I have a proxmox server with two small disks in raid1 ZFS created during the setup of proxmox.
On these disks there is only the operating system.

The VMs (and CTs) are on a second ZFS pool correctly backed up with VEEAM (except the CTs).

I know that to make backups of ZFS volumes you need to use file backup but I'm not sure which path to use to save everything on the disk.
For now I tried creating a job with the simple object /
It seems that inside there is all the content of the OS partition (which for MS Windows would be C:\)

The goal is that if for some reason the server does not start anymore I can:
- Install proxmox from scratch on the server
- Install the Veeam agent
- Restore the entire ZFS pool
- Restart the Proxmox server
-> Return perfectly to the situation before the failure
