I recommand to backup your firmware before uploading a new one. To do so on a Linux:
avrdude -C/AbsolutePathToConfigFiles/avrdude.conf -v -patmega2560 -cwiring -P/dev/ttyUSB0 -b115200 -D -Uflash:r:/AbsolutePathWhereToBackup/dump.hex:i
You will/may have to change AbsolutePathToConfigFiles, /dev/ttyUSB0 and AbsolutePathWhereToBackup
To be confident with your backup it is a good practice to perform it twice with different names and do a diff to check that everything goes well.
To restore the firmare, the command is:
avrdude -C/AbsolutePathToConfigFiles/avrdude.conf -v -patmega2560 -cwiring -P/dev/ttyUSB0 -b115200 -D -Uflash:w:/AbsolutePathWhereToBackup/dump.hex:i
