Release 4.5: BRBACKUP, BRARCHIVE, and BRRESTORE 

• Integration of the Recovery Managers into BRBACKUP/ BRRESTORE
  You can use the Oracle Recovery Manager (RMAN) to make an incremental backup of your database. In an incremental backup, only the changes that have been made since the last complete backup are saved. This strategy is particularly useful for large databases.
• New Device Type: backup_dev_type = stage | stage_copy | stage_standby
  You can make backups to a remote disk, without NFS mount. The transmission protocols ftp/ make this secure; you do not need to verify with -verify .
• Hardware-Compressing File Systems Under Windows NT
  As well as hardware-compressing tape devices, hardware-compressing file systems under Windows NT ( compress = hardware ) are also supported. This applies to: backup_dev_type = disk | disk_copy | disk_standby
• Backup with Automatic Deletion
  In the second phase of the two-phase backup you can use BRBACKUP/BRARCHIVE to integrate automatic deletion of files into the backup. If you choose this, the second phase consists of the disk backup being backed up to tape, followed by the deletion of the successfully backed up files from the disk.
