NetBackup for Oracle stream-based operations
Stream-based operations are the standard NetBackup implementation of conventional RMAN backup and restore. In a stream-based backup, NetBackup moves the data that the server process provides. NetBackup captures the data stream content that RMAN provides. If the user has specified multiple streams, then RMAN opens multiple streams and NetBackup catalogs them as separate images.
