LVTV,
Dave is correct - the deployment server can be offline without a major impact, assuming that the media objects are located on a different server. By default, the media objects are located on the deployment server. Moving the media objects is easy. Do a full copy of the directories, set up the appropriate network and sharing permissions.
From a setup perspective, change the paths in the Media Object Queues. That can be found here:
Foundation Systems > OneWorld Tools > Media Objects > Media Object Queues
One suggestion to improve a systems robustness, move the Media objects to a clustered server. In our case, our clustered server has the nodes in two different buildings, giving us high availibility and a good disaster recovery plan.
