In faubackup(8), the explanation of --atime-preserve appears to
contradict itself, or at least, the name of the option and the
description does.

It starts out making sense:

      "This  option  is directly passed to faubackup-gather.
      When set, faubackup tries to reset the access time  after
      reading files.

This, to me, sounds like -a for cpio, which resets the access time to its
original value, rather than marking it as having been accessed by cpio.
This is a good thing.  But the description then adds,

      "Don't use this option if you are using other backup
      software  in parallel, because  it might think that
      all your files have changed."


This suggests that --atime-preserve DOES allow faubackup to change the
access time, and does NOT set it back to its previous value.  Otherwise,
why would anything think all of the files had been changed?

I need faubackup to keep (or reset) ctime, mtime, and atime at the exact
times they were at before it backed them up.  Otherwise, it's going to
royally screw up anything using Makefiles, etc.....  So it is my
assumption (correct me if I'm wrong) that I NEED to use --atime-preserve.
If I'm wrong, which option DO I use?

Thanks,
