Our environment

Zenworks 10.3.4
Two primary servers - Windows 2008 R2 Standard SP1
One satelittle server - Windows 2003 SP2
Using patch management

Our content repository has grown to over 190GB and we're having problems as it's replicating to the other primary and satellite, both on disks smaller than 190GB.

My question is how to clean up/maintain this content repository. I've searched and cannot find the answer.
