Backup job stucks on loading media\device paused status

Hello

 

We are trying to run the multiple backups to tape library with single drive and then duplicate to Dedup folder. Using BE2012 sp1 and all updates are installed. Backup to tape has no issues but when duplicate to dedup runs the backup job will stuck on loading media and it says device paused. Currently we have multiple backup jobs starts at same time and duplicate jobs are also scheduled to fire on same time. Can anyone suggest what could be the reason of backup job goes into device paused status i mean we have set concurrent jobs on Dedup folder.

 

 

Thank you
