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:
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
Advanced feature: Provides hierarchical storage management (HSM) capabilities. For
more information about this feature, see Hierarchical Storage Management Use,
Figure 2-1 shows a typical flow of how BRMS implements your backup and recovery solution.
