3 * Bacula Director -- backup.c -- responsible for doing backup jobs
5 * Kern Sibbald, March MM
7 * Basic tasks done here:
8 * Open DB and create records for this job.
9 * Open Message Channel with Storage daemon to tell him a job will be starting.
10 * Open connection with File daemon and pass him commands
12 * When the File daemon finishes the job, update the DB.
