In Gnome, how do I backup my spell-check dictionary?

I have found these dictionaries in my system with locate:

/home/user/.config/enchant/en_GB.dic
/home/user/.config/enchant/en_US.dic
/home/user/.config/enchant/hu_HU.dic

Generally $HOME/.config contains all types of configuration for your programs.

update: I found the corresponding specification I was looking for: XDG Base Directory Specification.
