Database objects supported by advanced backup methods
Oracle controls the kinds of database objects that can be backed up by proxy copy and, therefore, what NetBackup can back up using Snapshot Client backup methods. Oracle allows proxy copy backups of databases, tablespaces, and data files. With Oracle 10g releases and later, Oracle also allows proxy copy backups of archived redo logs. As a result, NetBackup can use file-based Snapshot Client backup methods to back up these objects.
For control files, Oracle RMAN performs conventional stream-based backups only. NetBackup for Oracle must use stream-based backups for control files even when you use Snapshot Client methods for the other database objects.
The Oracle Intelligent Policy handles both stream-based and file-based components. File-based and stream-based backups require different configurations. When configuring your NetBackup for Oracle with Snapshot Client backups, be sure to configure a policy that allows both stream-based and file-based backups.
