Is there a Save button the user can click to save the work? If so, i would go with option 3 and save only the last state of the work. The Save button would allow the users to save their work everytime they want to, but theycan be assured that at least the last state is saved automatically.
Saving after every change is a bit dangerous if you do not allow to go back to more than one state. Just imagine, the user has done much work and unfortunately does 2 "unwanted" changes and want to go back to the state before of these 2 changes. That would be impossible without several backups. But shouldn´t your customer answer this question as the customer should know what option is needed on their side?
