Many times I work on embedded projects where it is required to save some 
data in a non volatile way.  Usualy I use external (to the main 
microcontroller) serial/parallel EEPROM or internal Flash memory (with a 
software layer for EEPROM emulation).

However my goal isn't to discuss the hw alternatives, but the data 
format and strategy.

I know there are many serialization data format (XML, JSON, Protocol 
Buffer, SQLite), but I don't think they are valid solutions for 
medium/low end microcontrollers.  They are complex to implement and they 
aren't really necessary.
Data are written and read from the same platform, so the endianess and 
byte order are not a problem.

IMHO directly saving a C structure to the non-volatile memory is the 
best method.  When you will load bytes from the non volatile memory, you 
will have magically your C structure in RAM filled with the saved values.

Is it the same strategy that you use?
