BackupExec 2010 R2 job stuck

Hi,



I have an issue with BackupExec 2010 R2 getting stuck on jobs. The job runs and then gets to a point where the status is "running" but nothing is actually happening. my normal full monthyl back-up is 2.1TB to 2.3TB but now the job will stuck in 1.9TB. i already change the tapes and used the cleaning tape. but same issue happen. :(
