When I set RTC date , rtc counter do not change.

when turn on again my board   date to 2000/1/1 Stm32f103zc + cube

I guess you'd need to review the code and how things shutdown, and the response when reinitializing.

The LSI is not powered in the low-power domain, only the LSE. The STM32's really like you to perform an orderly shutdown, not just pull the primary supply and hope.

I don't underestand  you.

/* RTC init function */ void MX_RTC_Init(void) {   RTC_TimeTypeDef sTime;   RTC_DateTypeDef DateToUpdate;             /**Initialize RTC and set the Time and Date             */             hrtc.Instance = RTC;             hrtc.Init.AsynchPrediv = RTC_AUTO_1_SECOND;             hrtc.Init.OutPut = RTC_OUTPUTSOURCE_NONE;             hrtc.DateToUpdate.WeekDay = RTC_WEEKDAY_MONDAY;             hrtc.DateToUpdate.Month = RTC_MONTH_JANUARY;             hrtc.DateToUpdate.Date = 1;             hrtc.DateToUpdate.Year = 0;             HAL_RTC_Init(&hrtc);                  sTime.Hours = 0;             sTime.Minutes = 0;             sTime.Seconds = 0;             HAL_RTC_SetTime(&hrtc, &sTime, FORMAT_BIN);                      HAL_RTC_SetDate(&hrtc, &DateToUpdate, FORMAT_BIN); } in this code always date set to 2000/01/01 and in   HAL_RTC_Init function repeat again. I have battery backup . when i turn on board again date  set to 2000/01/01 I remove it , but did not solve. when I call hal_rtcSetDate function . RTC counter must be change to higher value; this year is 2015. but do not change.

I don't have STM32F103 to test, so this code is taken and simplified from the examples provided by ST from STM32CubeF1. I don't know if this works or not, try to adapt to your code:

can eventually implement his proper time base source (a general purpose 
timer for example or other time source), keeping in mind that Time base 
duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and 
handled in milliseconds basis.

I test it. But not work.

Date reset after power up. When I call hal_rtc_setdate function , my RTC counter register , do not change. I do it with old stm library and work it. but this new cube library dose not work. I2c library has a problem too.

Maybe you haven't read this (in ..hal_rtc.c):

    (+) Date is saved in SRAM. Then, when MCU is in STOP or STANDBY mode, date will be lost.         User should implement a way to save date before entering in low power mode (an         example is provided with firmware package based on backup registers)
