Store RTC date into Backup Register

Hi there,

I'm using the RTC on my STM32F103 to keep the date and time but when I reset the MCU the date is lost.

I know that this behaviour is due to the RTC implementation ( it uses a counter ).


To prevent the date loss, I think to store the date into one or more backup register.

My date is composed by 3 byte (Year, Month and Date).


Could any one provide me a example about how to solve my problem?
