I have PVE host with 2 nvme drives, both are formatted in zfs and one is bootable - so extra bios and efi partitions. 2nd, non bootable drive is used as PBS storage.
I have also an offline backup copies of VMs, including PBS lxc (stored on main, bootable drive) done by PBS synchronisation jobs from other host.
I would like to make a backup of host’s rpool by utilisation of zfs send/receive commands - as rescue option for future failed drive (currently it has wear out at 114%).
The main issue is to restore bios and efi partitions; is there any kind of recommended procedure to follow?
Or maybe I should install Proxmox from scratch and then overwrite it with zfs receive? Or maybe copy over only /etc folder?
