I'm not sure what you mean. Do you have the Skydrive application installed? The one with the cloud icon in the system tray? If so, they should be uploaded in near real-time. I can work on a document, for example, and when I hit Save, I can see the green progress lines under the cloud icons in the system tray, meaning it's uploading automatically. If I have two systems on at once, any changes made on one appear almost immediately on the other.
