Thanks for this,

now setting RTC clock registers are working.

You are probably missing

  /* Enable PWR and BKP clocks */

  RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR | RCC_APB1Periph_BKP, ENABLE);

  /* Allow access to BKP Domain */

  PWR_BackupAccessCmd(ENABLE);

or you haven't actually disabled to the RTC interrupt.

The examples for the RTC are not particularly complete/comprehensive.
