ORACLE SECURE BACKUP

http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/10g/r2/prod/ha/ob/ob_otn.htm http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/11g/r1/prod/ha/osb10_2install/osb1.htm http://web.stanford.edu/dept/itss/docs/oracle/10gR2/backup.102/b14234/obadm_arc.htm What Is Oracle Secure Backup? Oracle Secure Backup supplies reliable data protection through file system backup to tape. The Oracle Secure Backup SBT interface enables you to use Recovery Manager (RMAN) to back up Oracle databases. All major tape drives and tape libraries in SAN, Gigabit Ethernet, and SCSI environments are supported. Oracle Secure Backup Features Oracle Secure Backup enables you to do the following: Centrally manage tape backup and restore operations of distributed, mixed-platform environments (see Oracle Secure Backup Installation Guide for supported machine architectures). You can access local and remote file systems and devices from any location in a network without using NFS or CIFS. Back up to and restore data from Oracle Cluster File System (OCFS) on Linux and Windows. Use wildcards and exclusion lists to specify what you want to back up. Perform multilevel incremental backups. Duplex database backups so that the same data stream goes to multiple devices. You can specify different media families or devices for each copy of the data. Create backups that span multiple volumes. Optimize tape resources with automatic 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 catalog for rapid retrieval. Maintain security and limit the users who are authorized to perform data management operations. By default, SSL is used for authentication and communication between hosts in the administrative domain. Oracle Secure Backup and Recovery Manager Recovery Manager (RMAN) is an Oracle Database-specific backup and recovery utility. RMAN is a built-in part of Oracle Database and backs up, restores, and recovers database files regardless of the type of disk storage used for these files. RMAN knows and applies the complex rules that must be followed to recover Oracle databases. If your database backup strategy needs storage resources other than local disk, then you must use RMAN in conjunction with a general-purpose network backup tool such as Oracle Secure Backup. Oracle Secure Backup can back up all types of files on the file system. Although Oracle Secure Backup has no specialized knowledge of database backup and recovery algorithms, it can serve as a media management layer for RMAN through the SBT interface. In this capacity, Oracle Secure Backup provides the same services for RMAN as other supported third-party SBT libraries. Oracle Secure Backup is better integrated with Oracle Enterprise Manager, however, than other media managers.
