There is more than one way to skin a cat..
If your flash disk is not mounted,
mount /dev/sda1 /mnt/sda1
cp yourfile /mnt/sda1
should get the file onto the flash (if it's seen as sda1)
Restoring it is the same except for the cp line where the arguments are reversed (and of course the mkdir is only necessary the very first time).
