HI Pete,

I cannot create package every now and then. We have close to 120 locations across the globe. I will create one package which will report the clients to the Default group. I will send this package to these locations where the local IT support will install when they image the OS. I am seeing GB of data downloading from SEPM server on few site where we have just 70 to 90 computers.

To Answer your Question, when SEP version 12.1 clients are deployed with Packages from SEPM, these packages are created with Latest definitions in it.

So as soon as SEP clients gets installed, the clients are installed with latest definitions.

Now, incase, these clients are Mobile machines, and then connect to the SEPM for definitions however, say incase, they are unable to fetch the entire downloads, then the next time it downloads it would download the same definitions again. 

i.e; It would fetch those days definitions which have not been received by Clients.

Here are few Article for you:
