16 Integrating Backup Recovery and Media Services and IBM Tivoli Storage Manager
2.1 General overview of the BRMS product
BRMS is the IBM strategic product on the iSeries server to assist in saving, restoring, and
managing media. BRMS has various backup options that allow you to specify what, when,
and where to save items. It allows for save while active and the ability to perform:
򐂰 Full saves
򐂰 Cumulative saves (saves only objects that changed since the most recent full BRMS save)
򐂰 Incremental saves (saves only objects that changed since the most recent BRMS save of
any kind: full, cumulative, or incremental)
You can perform attended or unattended backups and schedule backups using the native
OS/400 job scheduler or the Advanced Job Scheduler (5722JS1). BRMS gives you the ability
to control subsystems, job queues, the signing off of interactive users, initial program loads
(IPLs) and other work-management type operations. It automatically records what is saved
and the physical location of the tapes that contain the data. It also provides detailed reports
with instructions that explain how to recover your system.
The BRMS LPP supports three features:
򐂰 Standard feature: Gives you the capability to implement a fully automatic backup,
recovery, and media management strategy. It allows users to restore objects from a
specific date and time and allows the usage of tape libraries by controlling the mounting,
dismounting, and ejecting of tapes as required.
򐂰 Network feature: Enables BRMS systems to interconnect via a network to other BRMS
systems. This allows the systems to share media inventories and policies associated with
the media.
򐂰 Advanced feature: Provides hierarchical storage management (HSM) capabilities. For
more information about this feature, see Hierarchical Storage Management Use,
SC41-5351.
Figure 2-1 shows a typical flow of how BRMS implements your backup and recovery solution.

BRMS contains default values so you can begin using it immediately or you can customize
your backups to fit your backup strategy. There are two interfaces to BRMS:
򐂰 5250 interface (green screen): Within this client, there are two ways to navigate around
within BRMS as explained in 2.1.1, “5250 emulation interface” on page 18.
򐂰 BRMS iSeries Navigator client interface: See 2.1.2, “BRMS iSeries Navigator client” on
page 21, for more information.
There are some differences between the 5250 interface and BRMS iSeries Navigator client.
Within the BRMS iSeries Navigator client, you can set policy properties to perform functions
that you cannot set using control group attributes through the 5250 interface, including:
򐂰 Ending integrated Windows servers before backup.
򐂰 Ending hosted logical partitions before backup. Through V5R2, a hosted partition runs
Linux with access to a set of input/output (I/O) devices shared and a hosting OS/400
partition.
򐂰 Unmounting of user-defined file systems (UDFS) before backup.
򐂰 Starting integrated Windows servers after backup.
򐂰 Starting hosted logical partitions after backup.
