[Setup] Plone site backup and restore

[Myo Gyi]

Hi,

I have a plone site running well. But, because of I changed something in 
ZMI, I can't use PloneBook by Andy McKay. I think I change something in 
ArchiveType.

So, I tested by creating a new Plone site from ZMI and install PloneBook and 
it works!

What I want to do is, I would like to delete existing plone site and 
recreate a new one and restore data back. Then I will have a new plone site 
with new setting and old data. Can it be possible? If it can, please let me 
know hwo can I backup and restore data.

Regards,
Myo
