Backup job getting failed
We have Backup Exec 2010 R3 which is installed on 2008 R2 server.
We are running jobs on B2D and on tape, B2D jobs are running successfully but jobs which are schedule on tape are getting failed.
And our tape library is going offline very frequently.
Below is the error which is showing in logs.
