Hi You need to konw what dirs you are backing up for, then use du command to find out the size of the dirs, compare how much data you have and the size of your tape, then you
know the answer.

   eg. You want to backup /export/home,

    su as root,
    du -sk /export/home
    the output on the screen is in KB.

    You should able to work it out now.
