Cloning Databases 10
In Data Director, you can clone a database. You have a choice of cloning operations that include full database
clone, linked database clone, and schema only clone. You can customize the clone's database settings and
backup settings during clone creation.

Clone Types
Data Director allows you to clone databases and supports several clone types with different contents, storage
requirements, and performance characteristics.
You can create different types of clones depending on whether you need schema only, schema and data, full
database clones, or clones that take advantage of the linked clone technology. You can also create a clone that
includes neither schema nor data but includes resource settings, database parameters, and backup settings.
Schema Only Clone and Schema and Data Clone
If you create a schema only clone, none of the data in your database is cloned. If you create a schema and data
clone, the complete set of schema and data is included in the clone. In that case, you might have to run a script
over the clone to remove confidential data.
NOTE Linked clone technology for Oracle databases currently is not supported.
You can also clone only the configuration. In that case, the clone includes neither the schema nor the data.
Full Database Clones and Linked Database Clones
When administrators clone a database they can choose a full database clone or a linked database clone.
Full Database Clones
A full database clone is a complete copy of the source database. Full clones
allow you to isolate the source and the clone. The isolation might be useful, for
example, if the source database cannot tolerate any performance degradation.
Creating a full clone is typically more time consuming than creating a linked
clone.
