I use ntbackup to pack everything together then use 7z to compress and split up to 750MB pieces then use use imgburn. All these software are scriptable so it's great. What I am looking at this forum for a way to turn off update check. My backup was stopped because imgburn looked and found new update. I have set it to never but it revert back to weekly.
Attached is my set of scripts to do an incremental backup daily and normal weekly.
