    Hi Frank,

    This depends on your system. Ideally in backup the system would drain very minimal. In this mode only the 32K is active and the purpose is to maintain RTC. You can check the backup consumption, which i would guess you have already done (2.25uA + add minor margin). 

    You can use the above value for all calculations for your battery/super-cap/coin-cell.

    If the above does not help then please help understand your concern.
