Backup Exec 2012 doesn't seem to have an obvious method for creating a scheduled Unlock job for our tape libraries. But I was able to create what I hope will work with the following steps:
-Double click on the library to go into "Robotic Library details"
-Check mark "Pause" to pause the library.
-Click on Unlock... an unlock job will appear in jobs as ready;no idle devices status.
-Double click on the job and go to Schedule.
-You can now change it from Run Now to Recurrence with your desired schedule.
-UnPause the library.
But, you are stuck with what ever job name was created by default. That, evidently you cannot edit. This is just one of many examples of the inflexibility of BE2012 that makes it so maddening. Anyone have a better way? And yes, I know there's probably a command line method that can be launched with Windows Task Scheduler. But you shouldn't have to jump through hoops to do something that was so easily occomplished on previous revs.
I also find it anoying that the job doesn't show up with the backup jobs. Sure its not a backup job, but if I know I've got other jobs that will run over time on any given day and I want to put a hold on the device utility jobs, I don't want to have to jump around to various other screens to find them. I would like to have one master list of jobs like I did with Backup Exec 2010.
