Personally, I would also run backupcdr.bat and copy the Shoreline Communications folder.
- Open cmd prompt and go here: 
cd c:\Program Files\Shoreline Communications\Shoreware Server\Scripts - Then run 
hq_shoretel-stop-svcs.bat - Once all ShoreTel services are stopped, you can copy the "Shoreline Communications" folder to a network drive for backup
 - Once the copy completes, you can either restart the server or run 
hq_shoretel-start-svcs.bat
