Well, I guess no-one has such a script, or nobody is willing to share it
with you :)

Yup, this is what I do too.

No, you should be at the right place on the tape.

But you should really test by yourself before you lose data because 
I told you it was correct :)

There are some scripts in the example directory of dump (which get installed
into /usr/share/doc/dump-xxx/examples) which may or may not be useful to you.

Of course, there is also Amanda, which is basically a big pile of 
scripts on top of dump, but it will probably be overkill for your needs.
