The 31337 guys over at 4Hak3rs have written a guide for Quick & Easy Windows Home Server Backup and Restore. The WHS have duplication support for your data, but not the actual OS itself. So in the event of a disaster (or OS meltdown) you need to reinstall the WHS OS from a supplied restore DVD. All your data is still intact, but all your settings, users, add-ins etc are lost and needs to be reinstalled/recreated.
The above mentioned guide tells you how to create a new restore DVD from your existing setup so that you can roll back to what ever setup you have now.
Great news for all the HP MediaSmart owners (yes this tip is only for use since it makes use of the built in flash boot that’s in hardware).
