Summary: Use the Lync cmdlets to obtain a copy of the Lync topology.

 Instead of going through the GUI wizard, can I use Windows PowerShell to schedule a fresh copy
          of my Lync topology as a regular nightly task so I can compare deltas?

 Run the following Windows PowerShell cmdlet to create a file called Topology.zip with all of your topology:

Export-CsConfiguration -FileName C:\Backup\Config.zip
