We solved this problem by checking in full sql dumps of the content database into source control, in between major changes. Not that we ever had to check and see what went wrong with the content side - using an sqlite database pretty much ensured that things were in the right format before it hit the filesystem assets, and we had practially zero bugs from introducing this methodology to the project.
