• each job file needs to end in .job
• the following variables are passed on from the main script
  • BACKUPDIR -> path where the backupfile should be placed (e.g. /srv/backup-data/01_daily/2016-05-23)
  • FILEDESC -> datecode to be used in the filename
  • TEMPDIR -> can optionally be used for temp files
