Duplicate client in backup rotation

Hello All,

My Company has a NBU Master runs on a Unix OS with 12 Media server with Unix & Windows OS flavor with 1800+ client in backup rotation.

There is any way to find out duplicate of any client in backup rotation; recently I found a client was added in two different policies. Which created a 2 image of the same client, finally resulted in more tape utilization.

Could someone educate me if there is any command/script to detect all the duplicate clients under a master server?

Thanks
