During this process, your device may reboot many times like the flashing process, you are not recommended to use virtual machines or WSL because it might lose connection and cause the backup/restore process failed. You may encounter some missing files; you can open the recomputer-orin.conf and remove the file that didn’t exist. Usually these are temporary device tree overlay object files; they don’t affect the backup and restore results. But if you made modifications to BSP, you will need to merge your overlay files.
