non-rewind tape drive question.Need Urgent help.

Hi, I have problems to perform full backup on my tape drive. This command line is used to rewind the tape to the beginning when it finished the operation. mt -f /dev/st0 rewind. My question is how can I perform appending backups on the tape drive. Please anyone direct me how to do so. Your help is greatly appreciated.
