I have a text file I keep in an encrypted sparesebundle. I write things in there of a sensitive nature. I unmount the sparsebundle drive when I am done obviously. But I realized that Lion keeps a revision history of all the saves of that file when I click on the filename title. Where is that stored? Is my sensitive text file being stored somewhere accessible even though it's supposed to just be safe in the sparesbundle?? Not quite sure how this time-machine style versioning of files works when you're editing something you DON'T want saved somewhere accessible.
