recursion limits

[Chris Sheffield]

Thanks, Pierre, but I don't think that's quite what I'm after.  My  
backup program won't be something that will run consistently for  
weeks at a time.  I'm talking about recursion as in calling the same  
handler/function from within itself.  I'm guessing there could be  
issues with this if the folder to back up has a large directory  
structure, as in many sub folders and files.
