Using Tapes with Symantec Backup Exec 2010 r3 - Tutorial

Hi All,

I need a tutorial that explain the basic concepts of using tape with Symantec BE 2010 R3.

e.g I want to know if i use a tape that already has data on it, will that tape be overwritten.

I have a stand alone tape drive connected on the Dell MAchine T610. it can accomodate only 1 tape at a time.

Thanks.
