If you tried 'undo', then you must not have had the document still open after hitting save. 'Undo' does not work if you have closed the document. Undo only works for the session that the document is open.
If you never closed the document after hitting save and multiple undo does not work to go back to a previous state, then you may have greater system or application problems to investigate.
As you have found, InDesign does not behave like QuarkXPress in regard to backing up data over several versions. You may want to look at VersionCue if you have installed the entire Creative Suite.
