At my wits end for the journal error I can't find or get a answer on(see post 2/9 and 2/13).

These will probably seem simple and rudimentary to the rest of you but I have some questions regarding import/export of dns:

1. Can I export my entire DNS structure at once?

2. If so, can I delete it all at once?

3. Is there a way to leave out all DDNS generated entries on either export or import?

4. Upon import will it create all the in-addr-arpa zones and information?

5. Any caveats I should be aware of before doing this?
