Time Machine on OSX Lion: I never configured the appl. but still wonder if it were up and running, would it lead a person to deleted files? ... when I go to Secure Empty Trash and then to Erase Free Space x7, I assumed that deleted files were gone forever. When deleted are they deleted from the backup, too? I have Carbonite online backup. That keeps current within 30 days. Why would I want a backup of files in long past configurations? It does backup actual files, correct, but in past versions unless it hasn't changed since backup. Second, as for Revert File in Text edit: I know the number of past versions is limited; I use that for word processing. How long does OSX maintain them on a file that's been modified dozens of times over many months or years? Pls. advise and explain to someone who knows little of OSX even now... thanks.
