Oracle Secure Backup Features
Oracle Secure Backup provides reliable, centralized tape backup management,
protecting file-system data and Oracle Database files. The Oracle Secure Backup SBT
interfaceenables you to use Recovery Manager (RMAN)to back up and restore
Oracle Database files to and from tape. Oracle Secure Backup supports almost every
tape driveand tape libraryin Storage Area Network (SAN)and SCSIenvironments.
Oracle Secure Backup enables you to do the following:
■ Centrally manage tape backup and restore operations of distributed,
mixed-platform environments
You can access local and remote file systems and any tape devicefrom any
location in a network without using Network File System (NFS)or Common
Internet File System (CIFS).
■ Back up to and restore data from Oracle Cluster File System (OCFS) on Linux and
Windows
■ Encrypt all stored data
■ Use wildcards and exclusion lists to specify what you want to back up
■ Perform a multilevel incremental backup

■ Duplex database backups so that the samedata stream goes to multiple tape
devices
You can specify a different media familyor tape device for each copy of the data.
■ Create backups that span multiple volumes
A volumeis a unit of media, such as an 8mm tape.
■ Optimize tape resources with automatic tape drive sharing
■ Restore data rapidly
Oracle Secure Backup uses direct-to-block positioning and direct access restore to
avoid unnecessarily reading tape blocks to locate files. Oracle Secure Backup
maintains a record of the tape position of all backup data in its catalogfor rapid
retrieval.
■ Maintain security and limit the users who are authorized to perform data
management operations
By default, Secure Sockets Layer (SSL)is used for host authenticationand
communication in the administrative domain.
■ Manage media rotation from one locationto another
■ Automate tape duplication with user-defined policies
