Backing up just /home/root

To backup the home folder (all your files personal files in theory).

From the desktop pc run:

ssh root@phone 'tar -cpz /home/root' > moko-home-`date +%Y%m%d-%H%M%S`.tar.gz

Where phone is the ip address of your phone (192.168.0.202).

Personally I added an entry to /etc/hosts so the above works for me. I also added the desktop key to /home/root.ssh/authorized_keys on the phone as per the instructions in USB_Networking#SSH_Keys.

If you want to check what is in the backup, run the following, replacing the filename with what was just created.

tar -tzf moko-home-20080802-203108.tar.gz | less

Backing up everything

You will need the Dfu-util to make a backup of your existing image.

As when flashing, you will need to be in U-Boot in the NOR Flash. Log into the NOR uBoot menu and select Set console to USB (for NRF just stay in NOR uBoot menu, do not select or enter anything). Now you will be able to flash, make backups of your Freerunner or query the Freerunner with dfu-util. Backup is fairly slow; it took over ten minutes to back up a 247 MB rootfs.

It is important that you connect the USB cable directly from your computer to your phone. If there is a hub between them, backup (and flashing) will mostly likely fail.

NOTE: On a Windows host, omit the "./" or "sudo ./" that precedes the commands listed on this page


sudo ./dfu-util -a kernel -R -U good-kernel.bin
sudo ./dfu-util -a rootfs -R -U good-rootfs.jffs2
sudo ./dfu-util -a splash -R -U good-splash.bin
sudo ./dfu-util -a u-boot -R -U good-u-boot.bin
sudo ./dfu-util -a u-boot_env -R -U good-u-boot_env.bin

Here is what a successful dfu-util backup run looks like:
