hi
I use the following command to flash the system “./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml” --showlogs --network usb0 p3509-a02+p3767-0000 internal”, but how do I backup the system like before with the ./flash.sh -r -k APP -G command?
How to restore after backup? Corresponding to the previous ./flash.sh -r command?
thanks！

Hi 243953617,

Do you want to backup/restore the rootfs in NVMe drive?
If yes, please use l4t_backup_restore.sh instead and with some modification in the script.
You could refer to the following thread for detail.
