Backup Data
There are two types memory on the computer: Temporary memory RAM (Random
Access Memory) and permanent memory ROM (Read Only Memory). Optional
memory cards act like ROM.
Most data of ongoing program are stored in RAM. It would stay intact when power
turns OFF. (Actually pressing power button OFF/ON is “suspend/resume” only. Part
of the computer is still running, power supply to memory is always ON.)
However, data or program in RAM will be lost when hardware reset or master switch
turns OFF. And if primary battery been removed for too long time (for example,
swap battery for >1 minutes), there are risks to lose RAM data as back up battery
may run exhausted. Long time storage will drain primary and backup battery to
exhaust thus unable to keep memory data.
