1) Depends on the Kindle model.
Some, it is stored in a partition of the mtdblock device.
Other models only have the eMMC (mmcblk) device, it is stored there. Unusually in a locked, hardware write-protected area.
2) Yes to both, but requires special software tools. What tools depends on the model of Kindle.
3) How can what be backed up / restored on what model of Kindle?
4) The tools work at different levels of abstraction, some tools work at more than one level of abstraction.
Offer a specific question if you seek a more specific answer.
And in all cases, read the Freescale reference manuals on the model SoC you are intending to use.
Amazingly, after doing that, you should be able to answer most of your own questions above.
