Read/write Structure variable byte for byte

Hello,

For our application I need to copy data from the XDATA RAM to a I2C EEPROM.
How can a structure variable (in XDATA) will be read byte for byte? Then I will copy it to the EEPROM. It would also be necessary to copy the data from the EEPROM into the structure variable.

My structure is defined like this:

typedef struct
	{	BYTE	XPIDNr[9];
		char	UserName[UserNameLength];
		BYTE	Test;
		BYTE	Test2;
		int	Count;
	}StructUserRec;
