Yes, you would need to insmod paride, epat and pt, in that order. If
you already heard the tape drive moter running, chances are, you are
in business.

create a backup:
        tar cf /dev/pt0 DIRECTORY_YOU_WANT_TO_BACKUP

I am not sure you need to format the tape. I didn't, but then they were
pre-formatted. You can check whether everything went ok with

        tar df /dev/pt0 (note that you will get messages 'file does not exist'
                if you execute this command in the wrong directory.)

As far as erasing is concerned, I always simply overwrite the existing
but if you want to wipe sensitive data, you could do something like:

        dd -if=/dev/zero -of=/dev/pt0

I have tried it, but never let it run to the end of the tape, due to
a lack of patience. However, doing a listing shows that the tar is no
longer there:

        tar tf /dev/pt0

DISCLAIMER: I give _no_ garantuee that this will erase all data

Most people use tar, as do I. There are also dump, cpio, dd, afio.

The ftape documentation (Chapter 7) gives some good ideas how to use tar
for backup.
