I assume there are 4 level of backup/restore. If I'm wrong, please correct me.

1. Hosting or DNN installation.
2. Website or Portal
3. Page
4. Module

I have same questions for all of level:

1. How/ Where are we backup/restore data and code for each level?
2. Do we have auto backup function?
3. When develope a module, do we need to design backup/restore feature or DNN will do it for us?

Hello,

About DNN backup, just google and you'll find a lot of articles and how-to's
e.g. I remember a popular one written by Mitch Sellers

There is also a lot of excelent information about this topic at http://www.dnncreative.com/

>When develope a module, do we need to design backup/restore feature or DNN will do it for us?
DNN provides the IPortable interface. You can implement data import/export on your module

>Do we have auto backup function?
auto backup?

We have 2 popular modules for a DNN backup/restore solution (www.evotiva.com)

Thanks,
