It's quit easy to backup. Just open SpeedDial settings and click on the button in the lower left corner (this one with the arow beneath). There are two possibilities to export the settings - one for the settings and the other for the dials. They use the same filename but the contents are different IMHO - so you have to change it manually.

This review is for a previous version of the add-on (0.9.1).
