Just used SuperDuper's SmartUpdate to backup my TimeMachine drive - took around a quarter of the time it took Carbon Copy Cloner to do a block-by-block copy, so really really happy.

But - how can I be sure the backup is fully functional? Time Machine is a persnickety beast, and I'm not about to try and guess the procedure using commonsense! Anyone already taken the plunge, and can lay out the steps that definitely work - and which allow one to revert to the main Time Machine drive afterwards?
