Hello,
Do you see any active alerts in the Alerts tab?
How have you configured the jobs to run? Are the backups supposed to overwrite the media... do they span over more tapes? do the backups hang only during the verify process? Do you see a byte count?
Please clean the drive a couple of times... also ensure that the tape drivers, the SCSI drivers and the SCSI Firmware are the latest!
Do keep us updated on the issue!
Regards,
Asma.
