"Creating a Hierarchical Database Backup System Using Oracle RMAN and Oracle SAM QFS with the Sun ZFS Storage Appliance," a 23-page Oracle white paper, describes the implementation of a hierarchical database backup solution that is an ideal solution for users with three or more mission-critical Oracle databases, 40 terabytes (TB) or more aggregate backup data, and a requirement to keep backups on tape for longer than 180 days. With this solution a single DBA can be assigned control and management of database backup, restoration, and recovery.

Another in the series of What Works with What deals with SAM-QFS, an integrated hierarchical storage manager (HSM) and storage area network (SAN) file system. SAM, the announcement explains, is the HSM storage and archive management component; QFS is the SAN-scalable high performance file system component. SAM-QFS also has integrated disk volume management and tape volume management. QFS also has a write once, read many times (WORM) file system capability. QFS can be used independently of SAM when just a file system is needed. SAM requires QFS, however, and cannot be used independently of QFS. This "What Works With What" covers the specifics of what works with SAM-QFS (includes SAM-FS) 5.0 and QFS 5.0. This WWWW encompasses patch -01.
