Affirmative.  
[Copy 'n Paste Arduino Firmware - Community / Exhibition / Gallery - Arduino Forum](https://forum.arduino.cc/t/copy-n-paste-arduino-firmware/178469)

```arduino
avrdude -c arduino -P com9 -p ATMEGA328P -b 19200 -U eeprom:r:%temp%\backup_eeprom.hex:i
ECHO eeprom has been SAVED to backup_eerpom.hex

```

```arduino
avrdude -c arduino -P com9 -p ATMEGA328P -b 19200 -U eeprom:w:\Users\owner\AppData\Local\Temp\backup_eeprom.hex
ECHO backup_eeprom.hex WRITTEN

```

Obviously, com9 must be the Op's serial-USB port
