Use 'tee' for this:

  du -sh /media/boudiccas/backup/obnam-home 2>&1 | tee -a "$LOGGING2"

  echo 'Sending Backup report : Backup of obnam-home completed', $(date \
    -R) 'logged to' 2>&1 | tee -a "$LOGFILE"

To send the output of these commands to both their respective files, and
to stdout, which will get emailed out by cron.

Also, don't use capitalised variable names:

  By convention, environment variables (PATH, EDITOR, SHELL,
  ...) and internal shell variables (BASH_VERSION, RANDOM, ...) are fully
  capitalized. All other variable names should be lowercase. Since
  variable names are case-sensitive, this convention avoids accidentally
  overriding environmental and internal variables.

And finally, use more quotes, specifically around $LOGGING2, $LOGFILE, and
$(date ...):

  "Double quote" _every_ expansion, and anything that could contain a
  special character, eg. "$var", "$@", "address@hidden", "$(command)". Use
  'single quotes' to make something literal, eg. 'Costs $5 USD'. See
  <http://mywiki.wooledge.org/Quotes>,
  <http://mywiki.wooledge.org/Arguments> and
  <http://wiki.bash-hackers.org/syntax/words>.

Good luck!
