How can I back up the RootFS Image file from NVMe? I use Jetpack4.6,xavier,external device with NVMe,enable rootfs redundancy

Hi,

  1. When I use internal device with emmc, I can backup the image of rootfs with command“ sudo ./flash -r -k APP -G image.bak jetson-xavier mmcblk0p1”;
  2. But when I use external device with NVMe, jetpack4.6, I cannot back up using “ sudo ./flash -r -k APP -G image.bak jetson-xavier nvme0n1p1” command.

How can I back up the RootFS Image file from NVMe?

Thanks!
BR.

Hi,

There is no official tool to do that. Flash.sh is not able to flash or copy things from any external devices.

You can use below command on your Xavier to clone out the image.

img2simg /dev/nvme0n1p1 system.img.ext → this is create the backup image
