30 * Bacula Director -- migrate.c -- responsible for doing
33 * Kern Sibbald, September MMIV
35 * Basic tasks done here:
36 * Open DB and create records for this job.
37 * Open Message Channel with Storage daemon to tell him a job will be starting.
38 * Open connection with Storage daemon and pass him commands
40 * When the Storage daemon finishes the job, update the DB.

68 * Called here before the job is run to do the job
69 * specific setup. Note, one of the important things to
70 * complete in this init code is to make the definitive
71 * choice of input and output storage devices. This is
72 * because immediately after the init, the job is queued
73 * in the jobq.c code, and it checks that all the resources
74 * (storage resources in particular) are available, so these
75 * must all be properly defined.
77 * previous_jr refers to the job DB record of the Job that is
78 * going to be migrated.
79 * prev_job refers to the job resource of the Job that is
80 * going to be migrated.
81 * jcr is the jcr for the current "migration" job. It is a
82 * control job that is put in the DB as a migration job, which
83 * means that this job migrated a previous job to a new job.
84 * No Volume or File data is associated with this control
86 * mig_jcr refers to the newly migrated job that is run by
87 * the current jcr. It is a backup job that moves (migrates) the
88 * data written for the previous_jr into the new pool. This
89 * job (mig_jcr) becomes the new backup job that replaces
90 * the original backup job. Note, this jcr is not really run. It
91 * is simply attached to the current jcr. It will show up in
92 * the Director's status output, but not in the SD or FD, both of
93 * which deal only with the current migration job (i.e. jcr).
