Backup job kept failing with End Marker Unreadable error
I'm having some major issues with my backup servers where most of the jobs/media are having "End Marker Unreadable" error and causing the media to be unwritable. I had run some jobs on it but during halfway, the job stopped, the drive cleaning job took over and after complete, the media has this the above mentioned error. I had tried to clean the drive, erase all the tape and insert a new media, but all are failing. At first, we have erase the media and so far, it was working fine but these few weeks, it is failing although I had erase the tapes. Appreciate some help here, thanks.
