  3. # Simple rsync "driver" script.  (Uses SSH as the transport layer.)

  6. # Demonstrates how to use rsync to back up a directory tree from a local
  7. # machine to a remote machine.  Then re-run the script, as needed, to keep
  8. # the two machines "in sync."  It only copies new or changed files and ignores
  9. # identical files.

  11. # Destination host machine name
  12. DEST="smpent"

  15. # Are you sure that you want to run as root, though?

  29. # Options.
  30. # -n Don't do any copying, but display what rsync *would* copy. For testing.
  31. # -a Archive. Mainly propogate file permissions, ownership, timestamp, etc.
  32. # -u Update. Don't copy file if file on destination is newer.
  33. # -v Verbose -vv More verbose. -vvv Even more verbose.
  34. # See man rsync for other options.
  35.  
  36. # For testing.  Only displays what rsync *would* do and does no actual copying.
