Hello! How do I backup Jetson Nano Developer Kit and Jetson Xavier NX Developer Kit?
you may enable
-G options to back-up the image to the specified file with flash script.
please check this thread Could Jetson NX backup both mmcblk0p1 and external storage like /dev/mmcblk1 - #3 by JerryChang as see-also.
FYI, what @JerryChang mentions is the most thorough backup. You can also use
rsync, and instructions for using this from any web site will probably work perfectly well for a Jetson.
However, this is the Xavier forum, and Xavier has only an eMMC model. You mention using the Nano and the NX (which is not a full Xavier). The dev kits tend to live on an SD card, and you can back up SD cards on any host with very simple methods, e.g.,
dd. There would be no need to connect the SD to the Nano or NX and you could skip the “
-G” backup option and simply work directly on the SD.
There may be some content in the QSPI memory not backed up, but only the rootfs is really important. Any backup of the rootfs can be used to flash with, and the other content would be correctly placed without requiring any significant time. Do beware that the rootfs of one release is not compatible with the rootfs of another release.
