One of four Media Servers

[OnRappell]

I have a NBU 7.1.0.4 environment that has one master server (Win 2003) and four media servers (Also Win 2003). Using disk to backup. First to local storage and then duplicated from local disk on the media servers to two Data Domains. I am using Life Cycle Policies to make this happen set to Round Robin so that all four media servers are used. Recently, only one of the media servers has been preforming all of the backups while the others sit idle. They are all communicating with the master server and there is ample space on the local disk for backups to process. I have tried setting the LCP to Load Balancing, but get the same result. Any Help would be greatful.

Are you usingNetwork Optimized Duplication feature?

If the duplications / replications are using Opt Dup then it doesn't really matter which media server it uses as the actual process will go from de-dupe appliance to de-dupe appliance, the media server is just an incidental part of the process as it doesn't actually do anything

In general when you setup a Storage Server then in the credentials secton you have all media servers included within it as having access to it (first tab labelled Media Servers).

You find that if all are selected it will use any to do replications

The -required option is about the only way to prevent that happening in my experience other than unchecking the other media servers in this credentials section

The problem is not in the duplication, but in the backup itself. One media server is doing all the backups. I don't know if we are using the Network Optimized Duplication feature or not. Where in NBU do I check that?
