When looking at the common WSUS deployment options, I don't see an option where the updates are centrally managed for multiple WSUS servers, but both servers download the updates from Microsoft.

Is this a deployment option?

You can in WSUS 3, your replica server needs to be configured to store updates locally.

An option will be available to store updates locally, download files from Microsoft Update, but do not download from the upstream server. Mentioned here screenshot below:

Well, that would be nice to have illustrated in the deployment and storage docs. – mfinni Sep 20 '11 at 20:17
Good find - this doesn't seem to be anywhere in the documentation, I guess I should have taken a look at my server before answering! – Shane Madden Sep 20 '11 at 20:20
especially nice that the deployment guide details the following for Internally Synchronized WSUS [the upstream server] 'is the only server that downloads updates from Microsoft Update' - lies! :) – BoyMars Sep 20 '11 at 20:21
..and that "In replica mode, an upstream WSUS server shares updates, approval status, and computer groups with downstream servers." – Shane Madden Sep 20 '11 at 20:22
Looks like it got added to WSUS 3.0 deployment guide as "community content" but no such thing was added to the SP2 docs, at least as far as I can see. – mfinni Sep 20 '11 at 20:25

I know that there are 3rd party tools that will do this type of thing for you. We use N-Able's N-Central to do it, but it'd probably be a bit pricey for what you desire and is really specific to our industry.
