BRMS supports all IBM® media libraries (MLB) and has the capability
to support third-party library devices. An MLB is an automated media library.
You can store a large number of media in an MLB unit and access a specified
volume or volumes for read and write operations. BRMS determines which volumes
reside in the MLB, and when needed, issues the proper command to mount the
volume.
Media libraries enable
BRMS to provide the following support:
Perform save and restore operations automatically.
Perform file retrieve automatically.
Can migrate infrequently used data from DASD to less expensive storage
media while maintaining the ability to access it automatically.
Can archive massive amounts of data, such as in image or spooled archive
applications.
Provide hardware that new applications can use to manage offline storage.
