Dear sir,
Above to show you my log file, the sentence "Backup Set #2" which I hilighted with red means my tape is full and it need another tape ? If I backup only one single file, it was successful !

Pls tell me how am I going to empty up my tape ? Quick Erase won't help, because there are still data inside the tape. Veritas won't allow me to have long erase or format the tape. Any alternative way to wipe off the data frm the tape ?

Awaiting for your prompt reply. TQ
