I wanna backup physical partition where blackberry os (and apps) is installed. Desktop software is not suitable for this. I have to copy sector-by-sector the internal memory as a partition and flashing it when possible, for example in order to downgrade os, revert internal drive or the whole config.
link backup does copy everything in your device memory if you do a COMPLETE backup.
When you restore you can choose to only restore certain items if you don't want to restore the entire thing
