How to save custom shortcuts or keybindings on debian GNOME

According to ubuntu reference dconf is the most appropriate tool to manage shortcuts. Custom keybindings are stored in /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/, so we do

dconf dump /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/ > bkp

and bkp contains something like this:
[custom1]
binding='<Primary><Alt>t'
command='gnome-terminal &'
name='console'

[custom2]
binding='<Shift>Print'
command='gnome-screenshot -a'
name='screenshot-to-/home/asalle/Pictures'

[custom3]
binding='<Primary><Alt>i'
command='iceweasel'
name='iceweasel'

After this, put the bkp file into the cloud or elsewhere, where it can be safe and restore keybindings, if necessary, with:

 dconf load /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/ < bkp

Sorry, guys, I haven't tried the last one, so I am not sure if it works.
