I am also unsure of whether this is the best way, but I have done
something similar with a backup script before:

Excerpt from:
<http://wellylug.org.nz/index.php?page=articles/article-display.php&&id=10>

working_dir="/tmp/backup/$(date +%Y%m%d)/" 
... 
if [ ! -d $working_dir ]; # check directory does not exist already
then mkdir -p $working_dir; 
else 
  echo 
  echo "Not proceeding because $working_dir exists! If there is nothing " 
  echo "important in that directory, delete the directory and rerun
this script."
  echo 
  exit; 
fi; 

Hope that helps.
