1. IBM Tivoli Storage Manager
Component overview

2. Objectives Upon completion of this unit, you will be able to:
� Identify how Tivoli Storage Manager serves as an application
for data management and protection.
� Identify major components of the Tivoli Storage Manager
solution.
� Identify the optional Tivoli data products that are part of the
Tivoli Storage Manager solution.

3. Tivoli Storage Manager: An enterprise-wide solution
stores copies of data off-site.
� Tivoli Storage Manager
scales to protect a large
number of computers that are
running a variety of operating
systems.
� Tivoli Storage Manager
provides intelligent data
move and store techniques.

5. Tivoli Storage Manager server instance
In a typical LAN configuration, the Tivoli Storage Manager
server stores the backup or archive data from the backup-
archive clients that it supports to the storage media. The server
also has a database for managing data, including policy
management objects, users and administrators, and client
nodes.
Tivoli Storage Manager server refers to an
instance, not a physical system. You can have
multiple instances of the server on the same system.

6. Scheduler
Administrator-defined schedules allow for the automation of Tivoli
Storage Manager server and backup-archive client operations. A
comprehensive and integrated set of schedules can provide the
basis for efficient data management with little need for
intervention during normal operations.
Scheduling Tivoli Storage Manager backup-archive client
operations consists of schedules on the Tivoli Storage Manager
server and a scheduler component that runs on the Tivoli Storage
Manager backup-archive client machine.

7. Backup-archive client
The Tivoli Storage Manager backup-archive client is a service that sends
data to and retrieves data from a Tivoli Storage Manager server. The
Tivoli Storage Manager backup-archive client must be installed on every
machine that transfers data to server-managed storage called storage
pools. This machine might be a workstation, a file, or a database server.
The Tivoli Storage Manager server uses a unique node name to identify
each Tivoli Storage Manager backup-archive client instance. The Tivoli
Storage Manager backup-archive client supports encryption, and a
password can be used to authenticate communications between the
Tivoli Storage Manager backup-archive client and server.

8. Tivoli Storage Manager database
When the Tivoli Storage Manager server is installed, a database and
recovery logs are created. Tivoli Storage Manager saves information in
the Tivoli Storage Manager DB2 database about each file, logical volume,
or database that it backs up, archives, or migrates.
The Tivoli Storage Manager database is the heart of Tivoli Storage
Manager. Later in this course you will see how to protect the Tivoli
Storage Manager database, which is critical for data restoration.

9. Tivoli Storage Manager recovery log
The server uses the recovery log as a scratch pad for the database,
recording information about client and server actions while the
actions are being performed.

10. Storage pools
Storage pools are collections of similar media that provide storage
for backed up, archived, and migrated files. These pools can be
chained to create a storage hierarchy.
Any supported sequential media can be used in all copy storage
pools.
Data moves from the primary disk
pool to file pools or disk pools to
tape pools
Data moves from the primary disk
pool directly to tape pools.

11. Policies enable data management based on
business requirements by defining the
following information:
Active Policy Set
� Which files are eligible for back up
� Which files are eligible for archive
� Where data is stored
� How long data is retained
� How many versions of data are retained
Inactive Policy Set

12. Backup and restore functions
The backup-archive clients send
copies of files to a storage pool,
and the database makes a
record of the transaction.
The Tivoli Storage
Manager server stores
copies in the storage
pools.
Restore:
Copies of files are returned to
the backup-archive client using
information in the database.

13. Archive and retrieve functions
The backup-archive clients
send copies of files for retention
to Tivoli Storage Manager
server.
The Tivoli Storage Manager
server stores the copies in
the storage pools.
Retrieve:
A copy of the files are returned
to the backup-archive client.

14. Tivoli Storage Manager supports a variety
Storage media
Tivoli Storage Manager supports a variety
of tape and optical libraries as well as
storage media types for copy storage pools,
including:
� Tape
� WORM
� Optical
� Disk
� CD-RW
� DVD-RAM
� File
storage pools
storage
devices
� Virtual tape (VTL)
