Based on this error it seems like it could be a bad tape possibly?  I would check the logs for the job here - C:\ProgramData\Veeam\Backup and then the subfolder for the tape job.  Hard to say but might also be best to open a case and post in the forums too -

Has this worked initially or do you have this error since the beginning? Could be hardware related or maybe a driver/firmware issue. I would suggest that you check if everything is up to date and that there are no errors in the library itself.
