Time Machine works as an archival program from what I understand of it. To me this means it will go back to date specific times and show the available data at that point in time. So if I delete something today that was archived by TM at an earlier date, will it have that data available to be retrieved tomorrow? Also if this is the case, can I limit the range of dates or time? It seems to me that TM will quickly fill my backup drive if it retains everything that ever crossed into my system. I hope I'm being clear.
