Here's a question I've been trying to get an answer to:
Apple tells us that they will rollup the hourly snapshots into a single daily one. Similarly they will do the same for other time periods, but let's just stick with the hourlies.
Now, say you have created a file (call it mywork) and made changes over 3 hours and then deleted it. Thus you end up in TM with the equivalent of 3 files in TM, mywork(1), mywork(2) and mywork(3). If you go back in time while the hourlies still exist, the Finder will present you with each of these files in their respective time frames and call them just mywork.
Now, however, we reach the point where the hourlies are rolled up. What happens when you go back in TM to that day?
1) TM keeps ALL versions of the file and you see mywork(1), mywork(2) and mywork(3) in your folder.
2) TM keeps the last version of any file that ever existed in any hourly that day and thus only mywork(3) shows up on that day (named, of course, just mywork).
3) TM removes any file that does not exist in the final hourly for a given day. Thus, when you go back there is no file there.
