Can the database schema be reliable as re-storable copy of the BRMS Knowledge Base ?

Issue

• Can the database schema be reliable as re-storable copy of the BRMS Knowledge Base ? I've been able to restore my BRMS Knowledge Base from the exported repository which we get in form of a zip file from BRM (i.e. Guvnor) , and so a I can consider it as re-storable copy of my Knowledge Base. However, I didn't find a way to restore my Knowledge Base starting from the DB schema.
