Don't.  We're all quite happy to rip in your mistaken beliefs!!  Bwah
hah haha!  

Ok, seriously.  Don't worry, we all have questions we think are dumb
or silly or embarrassing, but hey ask anyway.  And we won't give you
grief at all.

Well, the general issue is open files.  And files created after the
backup process starts.  

For example, if you are doing an incremental backup of just the files
that changed since the previous backup, you need to do two passes.
Well, not quite, you can optimize it, but there's definitely a window
where a file can be created (or deleted!) between the initial scan of
the directory and the actual reading of the file to be sent to tape,
disk, whatever.
