154 Implementing IBM Tape in i5/OS
6.1 Introduction to BRMS
With growing capacity and increasing requirements for managing information, System i
customers require a tool to manage their saves and restores. Although some years ago, many
System i shops could cover their backup requirements by simple i5/OS commands, nowadays
they require software to manage their complex backups and take care of a growing amount of
data cartridges.
Backup Recovery and Media Services (BRMS), a licensed product in i5/OS, meets these
customers’ requirements. It provides capability for fully automated backup, as well as
comprehensive and efficient management of data cartridges. By using BRMS, the customers
can recover their entire system, or single objects. With BRMS, it is also possible to share tape
devices, use virtual tape drives, and use Tivoli Storage Manager for System i backups.
Advanced features of BRMS enable customers to archive data to various media, and
dynamically retrieve data. The Network feature of BRMS provides management of multiple
BRMS systems that share the inventory of media and backup policies.
The BRMS functions fall into six key areas, as follows:
򐂰 Managing your media:
Tracks the contents of your tapes as they are written
Prevents overwriting active tapes
Provides move reports showing which tapes should move to different locations each
Provides lists of tapes that should be in each location at any given time, and so on.
򐂰 Automating your backups:
Sets up your backups in a standardized format that others can understand easily
Supports save-while-active, object-level saves, spooled file saves that maintain print
attributes, saves to Tivoli Storage Manager, and so on
For more information about the save-while-active function, refer to the System i
Information center at the following Web site:
Provides detailed reporting on activity and errors, and so on
򐂰 Simplifying your recoveries:
Shows you all the saves of a certain set of objects so you can choose which generation
you want to restore
Provides interactive restores of those objects, complete with operator mount messages
as appropriate
Simplifies full-system recoveries by providing reports showing ASP configuration,
tapes required for recovery, and detailed steps for recovery; automates those steps
once the BRMS product is back on the system
Provides an on-line progress report during a recovery.
򐂰 Hierarchical Storage Management (HSM):
Migrates objects among disk pool based on age, size, and usage criteria
Archives objects to tape based on age and usage criteria
Dynamically recalls *file objects, folders, and stream files when accessed by a user or
application, and performs interactive recalls of other object types
