The reset signal will reset the chip and is probably too late for you to do anything. You could program the SVS to generate an interrupt when Vcc drops below a certain level.

He can also use the NMI/RST pin as NMI and use a comparator to
detect when the main power is below some value.
As main power I mean the supply voltage before the 3V regulator.
Then he can use some miliseconds to save all data before the 3V
supply falls below safe levels.
