So off I google looking for a way to get the same functionality from my 25gb Skydrive. Low and behold someone else had the same idea on Microsoft answers and the solution is relatively simple.
It involves right clicking my documents folder, selecting the location tab and changing the location to a new location under the local Skydrive folder, then once all the documents have been moved Skydrive will sync this in the cloud and bingo, a synced document backup in the cloud.
