+======Bareos SD power on/off======
 =====Introduction=====
-I have a SAS tapedrive connected to a dedicated server for backups. On this machine bareos-sd is running. I do not want the bareos-sd server powered on all the time when it is only backup-ping a litte time of the day. So I have made some scripts to power on and off the server.
+I have a SAS tapedrive connected to a dedicated server for backups. On this machine bareos-sd is running. I do not want the bareos-sd server powered on all the time when it is only backup-ping a litte time of the day.
+So I have made some scripts to power on and off the server.
 The server is a Supermicro machine with IPMI, so I am using ipmiutils to power on/off the machine.

+=====Powering off the SD=====
+The catalog backup runs with a lower priority so shutting down the server after the catalog backup makes sense. In a schedule I always end with creating a catalog backup. When the SD is powered down, I do not want to power it down again.
+=====Catalog backup=====
+<code - /etc/bareos/bareos-dir.d/job/catalog.conf>
+Job {
+  Name = catalog
+  Client = backup-mngt-bh
+  Type = Backup
+  Level = Full
+  Storage = disk-bh
+  Pool = disk
+  Messages = Standard
+  FileSet = catalog
+  Schedule = catalog
+  # Default
+  #RunBeforeJob = /usr/lib/bareos/scripts/make_catalog_backup
+  # Helux
+  RunBeforeJob = /usr/lib/bareos/scripts/make_catalog_backup.sh
+  # Default
+  #RunAfterJob  = "/usr/lib/bareos/scripts/delete_catalog_backup"
+  # Helux
+  RunAfterJob  = "/usr/lib/bareos/scripts/delete_catalog_backup.sh"
+#  Write Bootstrap = "|/usr/bin/bsmtp -h localhost -f \"\(Bareos\) \" -s \"Bootstrap for Job %j\" root@localhost" # (#01)
+  Priority = 11
+}

+=====Powering on the SD when running a job=====
+When I need to write a backup to the bareos-sd server, I need to power it on. But I do not want to power it on when it is already on. It is possible a job will be triggered with another job still running.
+<code - /etc/bareos/bareos-dir.d/job/example.conf>
