Questions re datapump import
Sent by:

I want to use datapump export and import as simple method of backing up schemas in our development environments.  

i.e. to restore the schema to a previous state, I would import back into the same schema.  

If I do a full schema import using datapump, will the fact that the database objects already exist cause issues? Will data rows in tables be duplicated?  

Or is there a better way of backing up and restoreing a single schema?  

I do not want to drop the schema between doing the export and the import.
