Of course it is a good idea to back up your app before making any changes, 
but I wouldn't say there is "no way back." Files that contain pickled 
objects are the *.table database migration files, session files, and error 
tickets. It is easy to generate a new set of *.table files by setting 
fake_migrate_all=True, and session files and error tickets are generally 
ephemeral anyway.
