13 Backup system administration
The optional RISS backup system is the final line of defense in the integrated RISS data-protection strategy.
The RISS backup system uses Tivoli Storage Mana ger (TSM) to create backups of RISS data.
This chapter describes the processes involved in accessing the RISS backup server, configuring TSM,
and managing smart cells, a nd contains detailed procedures for maintaining and labeling backup
files and media. It includes the following topics:

RISS backup strategy
The RISS b ackup option is the final line of defense in the integ rated RISS backup strategy. The first line of
defense is that each smar t cell group contains two mirrored smar t cells. If either of these cells fails, then
the su rvivor can be cloned to recover the mirrored pair. To offer further protection, when a RISS system
is replicated, the replicated system also maintains two additional cells that can be used to recover the
origi
nals. The RISS backup system is utilized only in the event that all mirrors and replicas are lost.
After
the RISS backup option is installed, administrators have the choice of which RISS store domains they
want to back up. All store domains can be backed up if desired.
Tivoli Storage Manager
Tivoli Storage Manager 5.3 (TSM) is used to per form backups to external media. You should have a
thorough understanding of TSM before attempting backup procedures. This guide explains the most
important TSM concepts involved in RISS m a nag em ent.

Administrator’s Guide and the Administrator’s Reference.
Gaining access to the RISS backup server
A RISS system that has been configured with the backup option has one central backup server machine
that runs Tivoli Storage Manager software. This backup server is named INTERNAL and is available at IP
10.0.105.1. Use any of the following methods to access this backup server:
• Use the RISS KVM console to access the backup ser ver directly.
• U
se the RISS PCC machine for remote access:
