* This update causes the backup process to run in a separate thread. 

* Concurrency issues are resolved because each object makes a memory-only copy of itself and backs up the copy.
* Because of the way this is done, the latest at the time of the backup gets backed up (no functionality change)
* You can move *thousands of objects at a time* and the sim doesn't freeze and wait for the backup to complete.
* This can be enhanced more by dedicating the thread as opposed to starting it when the backup process starts.
