I have a AGX Orin device with documents and few packages installed. now i need to create a backup of this device and then reflash this backup to another AGX Orin board, how to do it?
Please refer to Linux_for_Tegra/tools/backup_restore/README_backup_restore.txt.
I ran this command :
sudo ./tools/backup_restore/l4t_backup_restore.sh -e mmcblk0p1 -b jetson-agx-orin-devkit
I encountered this:
ln -s /proc/self/fd /dev/fd && mount -o nolock [fc00:1:1::1]:/home/inbe1e-dt2300cn/orin/Linux_for_Tegra/tools/backup_restore /mnt && /mnt/nvbackup_partitions.sh -e mmcblk0p1 -n && echo Backup image is stored in /home/inbe1e-dt2300cn/orin/Linux_for_Tegra/tools/backup_restore/images
on root@fc00:1:1::2
mount.nfs: Connection timed out
What should I do ?

You need -e mmcblk0 instead of -e mmcblk0p1.
still i’m getting this :
ln -s /proc/self/fd /dev/fd && mount -o nolock [fc00:1:1::1]:/home/inbe1e-dt2300cn/orin/Linux_for_Tegra/tools/backup_restore /mnt && /mnt/nvbackup_partitions.sh -e mmcblk0p1 -n && echo Backup image is stored in /home/inbe1e-dt2300cn/orin/Linux_for_Tegra/tools/backup_restore/images
on root@fc00:1:1::2
Maybe find another host PC/USB cable and try again.
I used this command to create a backup image:
sudo ./flash.sh -r -k APP -G my_backup.img jetson-agx-orin-devkit mmcblk0p1
this created a my_backup.img and it stored it in Linux_for_Tegra/
now how do i use it to restore the backup?
also what is the purpose of system.img and system.img.raw?
Then you can do
sudo ./flash.sh -r -K APP jetson-agx-orin-devkit mmcblk0p1
system.img.raw is a direct clone of the rootfs, which takes up as much space as the partition, even if it’s not full. system.img is a sparse image, which is generated by trimming unused space in system.img.raw, so it’s smaller in size.
It’s the sparse one that really gets flashed into devices.
can i replace the my_backup.img.raw with the system.img under bootloader/ and run:
sudo ./flash.sh -r jetson-agx-orin-devkit mmcblk0p1
and also
system.img is just a backup image of the current flashed image and if in future if i want to reflash the same i can use flash script with -r option?
You need the sparse image but not the raw image.
Also. -k APP only flashed the APP partition, which may save some time, but maybe no much difference.
YES.
I should copy only my_backup.img and not the .raw file?
You can do both, but it’s system.img that really gets flashed, not system.img.raw.
ok thank you
