Offline entity sync

[Jeff Burton]

I'm running into a problem where an initial entity sync (pull from 
server to POS) in order to load starting data is too time consuming 
and doesn't seem to be the best method for the task.  I see there's 
an offline entity sync service and wonder if this may be more 
appropriate approach.  What's the quick and dirty explanation of how 
this is setup and operates?  Thanks.
