You might want to use external backup programs if you need to back up a large Oracle database. We provide the BACKINT interface for this purpose. For more information, see External Backup Programs for Large Databases.
The main advantage of using the BACKINT interface with external backup programs is that you can use other backup media, for example, magneto-optical (MO) media. Alternatively you can transfer volume management to other systems, for example, automatic tape changers, such as jukeboxes and tape robots.
You can obtain information on the throughput and performance of external backup programs from the vendors providing the external backup.
