What hard disk?
If you're talking about the flash, just connect it to your linux PC and then:
sudo dd if=/dev/sdX of=/destination/to/backup.img
Where X is the device letter of your USB connection. Or if you don't have a linux PC (neither do I,) linux in virtualbox works fine, just run it as admin so it can capture the USB connection.
Everything outside of that user space can be restored with webos doctor.
