Hi Lextendo,
I am afraid that you will not be able to achieve this functionality with the ObjectContainer class. The object container is used to carry persistent object and track their changes in cases when the database is not available. What you want to do is create a changeset with the differences between two databases, which is completely different functionality that unfortunately we do not provide at the moment.
You will either have to manually read the last inserted/updated/deleted objects and synchronize the databases or use a third party synchronization framework.
All the best,
