As mentioned, RDP to your server and open Syslog Viewer. Click on View and select Alerts/Filter Rules.
The first rule will be "NCM Rule: Cisco IOS Realtime Change Notifications"
Copy this rule and you could name it "NCM Rule: Cisco IOS Realtime Change Notifications - SG300"
Then go to the Message tab and change the Syslog Message Pattern to something like
*SW-IT-ACC-1 COPY - FILECPY*
Save that and you're good to go. Make sure this rule is second from the top in the rules list.
