Autonomous Database provides cloning where you can choose to create a full clone, create a metadata clone, or create a refreshable clone. You can also use cloning to upgrade your database to a newer Oracle Database version when newer Oracle Database versions are available. You can move an Autonomous Database to a different Oracle Cloud Infrastructure compartment.
When you create a clone for an Autonomous Database instance, you have the option to select the clone type:
Full Clone: creates a new database with the source database's data and metadata.
Refreshable Clone: creates a read-only full clone that can be easily refreshed with the data from the source database.
See Using Refreshable Clones with Autonomous Database for more information.
Metadata Clone: creates a new database that includes all of the source database schema metadata, but not the source database data.
For a Full Clone or a Metadata Clone, you have the option to select the clone source:
Clone from a database instance. This creates a clone of a running database.
Clone from a backup. This creates a clone when you select a backup from a list of backups, or when you enter a backup point-in-time to clone.
When an upcoming release is available for preview with Autonomous Database, you can clone your existing database or clone a backup, to use the preview version. A preview version is only available when there is an upcoming major version to release. At times no preview version will be available.
