Using Schema Export/Import Wizard
Schema export and import wizards are intended to help DBAs to backup
You can select any of five levels to compress your files, use auto delete
of old Oracle backup files to free your disc space, choose information to export,
and set extended options for a database to export, backup structure, users, or a
script. Unlike binary Oracle backup process, database is dumped in SQL format.
There is also a possibility to save your settings along with connections
as a project for the next time or for using them in the command line interface.
