Monitor backup result and send e-mail.

Hello.

I am trying to create a powershell script that will check the last 3 backups taken om my domain controllers and send the result of that to chosen recipients with e-mail.

 The main problem i have noticed is that when i run get-wbjob -previous 3 command it will only generate the result on the local server. Is there any way to query cross server or will i have to create a scheduled task for each DC?

Thanks
