The IBM Tivoli Storage Management solution
In todays connected world, data has become the key asset of companies and one of its most
important competitive differentiating factors. Temporary inaccessibility or the complete loss of
data has a huge financial impact, and can drive companies out of business. The inability to
manage data can have a negative impact on a companys profitability and can limit their ability
to grow. Storing, protecting, and managing data growth are now among the major challengesof todays businesses.
Today's storage management needs to go beyond traditional backup and recovery solutions.
Data is the currency of today's e-business economy, and planning to store this data needs to
encompass data reliability, solution scalability, disaster planning, and recovery. This will
impact the overall infrastructure as well as individual mission-critical applications.

4 IBM Tivoli Storage Manager : A Technical Introduction
Enterprise protection implements an enterprise-wide solution for data protection, disaster
recovery, space management, and record retention. It covers all types of heterogeneous
system platforms ranging from mobile systems up to large scale enterprise servers, and
supports all types of storage resources, including locally attached as well as network or SAN
attached storage. Flexible storage management policies support business needs and provide
powerful automation features thus eliminating labor intensive and cost intensive manual
storage management tasks.
Strategic business applications are typically complex collections of interdependent
components from both commercial and proprietary software, and span desktop, distributed,
and mainframe computing environments. Application protection is concerned with the data
availability, performance, and recoverability, and integrates the application data management
into enterprise data protection.
Storage Area Network (SAN) architectures add a new dimension to storage and data
management by providing a separate, dedicated network to allow businesses of all sizes to
provide access to and share data, regardless of operating systems. IBM Tivoli Storage Area
Network Manager is a significant step towards helping customers cope with the explosive
growth of information in the eBusiness age. SAN management is concerned with the efficient
management of the Fibre Channel based SAN environment. Physical connectivity mapping,
switch zoning, performance monitoring, and error monitoring are among the most important
features.
Given the growth in enterprise storage, there is a consequential increase in the number of
devices and logical units that would benefit from central management. IBM Tivoli Storage
Resource Manager provides logical management, reporting, and predictive capacity planning
for these storage resources in order to ensure that the enterprise makes the best possible
use of the resources that it owns. IBM Tivoli Storage Resource Manager for Databases
provides the added capability to monitor and manage storage usage within various database
products again, with the objective of efficiently managing the available storage resources.
IBM Tivoli Storage Resource Manager for Chargeback uses the information gathered by IBM
Tivoli Storage Resource Manager and IBM Tivoli Storage Resource Manager for Databases
to calculate chargeback information and generate invoices for storage usage.

IBM Tivoli Storage Manager
IBM Tivoli Storage Manager is the core product of the IBM Tivoli Storage Management
product set. It provides a solution for distributed data and storage management in an
enterprise network environment. IBM Tivoli Storage Manager protects and manages data
from more than 30 operating platforms, covering mobile, desktop, and server systems over
the entire distributed world. It supports hundreds of storage devices (including disk, tape, andoptical) as well as LAN, WAN and SAN infrastructures.
These are the base functions provided by IBM Tivoli Storage Manager and its complementary
products:
Data protection, including:
Operational backup and restore of data: The backup process creates a copy of the data
to protect against the operational loss or destruction of file or application data. The
customer defines how often to back up (frequency) and how many numbers of copies
(versions) to hold.
The restore process places the backup copy of the data back into a customer-designated
system or workstation.
Disaster recovery: All activities required to organize, manage, and automate the
recovery process from a major loss of IT infrastructure and data across the enterprise.
This includes processes to move data offsite into a secure vault location, to rebuild IT
infrastructure, and to reload data successfully in an acceptable time frame.
Data resource management, including:
Vital record retention, archive and retrieval: The archive process creates a copy of a
file or a set of files representing an end point of a process for long term storage. Files can
remain on the local storage media or can be deleted. The customer controls how long
(via the retention period) an archive copy is to be retained.
The retrieval process locates the copies within the archival storage and places them back
into a customer-designated system or workstation. Space management (or hierarchical storage management): This process provides the
automatic and transparent movement of operational data from the user system disk space
to a central storage repository. If the user accesses this data, it is dynamically and
transparently restored to the client storage.
The solution is network based, which means that these functions are available to the whole
network environment. All the functions can be automated to run in a 24X7 lights-out
environment. Administration costs are minimized by centralization of all of the management of
IBM Tivoli Storage Manager components.
IBM Tivoli Storage Manager architectureGood backup and restore requires thought! This statement may seem obvious, but there is a
big difference between solutions implemented well, with careful thought and effective testing,
and solutions implemented as an afterthought with little or no planning and with no testing. It
is an unfortunate fact that many people only discover that their backup processes are
inadequate when they need to restore data.

6 IBM Tivoli Storage Manager : A Technical Introduction
Backup design
Any backup and restore tool is only as good as its implementation. Cars are extremely safe as
long as no-one crashes them, but people still manage to do so. Many storage tools are
designed to provide excellent backup capability, but the key to making them work effectively
relies on a good understanding of what data needs to be restored, and when, including the
testing of that restore, thus ensuring that the tools have been implemented in the right way.
IBM Tivoli Storage Manager is designed with restore in mind. Its functions and features do
provide an efficient and easy to use backup capability and will manage data storage, but the
primary objective is to be able to restore data when needed, since that is the only real reason
to take a backup.
Typical key factors for restore are:
What data would I need to restore?
When might I need to restore it?
In what time scale would I need to restore (recovery time objective)?
How much data can I afford to lose (recovery point objective)?
What type of data is it files, databases, raw volumes?
What post processing will be needed to make the data usable?
Perhaps this is an obvious statement, but the most important factor when thinking about
restore is to obtain clear and well described requirements. This is easy to say, but how often
have people said I want to back up everything and keep it forever? This is both unhelpful and
potentially extremely expensive. Any backup, as for many aspects of IT, will be a compromise
between speed of recovery and cost of solution. Almost any volume of data can be restored
quickly provided that the backup was taken in the correct way and that appropriate equipment
is available; however, would such a solution be cost justified?
Backup designers should also be wary of mixed backup and archive requirements. A very
common request is for weekly, monthly, and yearly backups to be taken, with appropriate
retention periods. The restore requirements for these backups are different: the first (weekly)
are typically for operational recovery, as described above; while the monthly and yearlybackups are more likely to be for audit requirements and are, therefore, archives, not
backups. Different processes may be required to meet all these requirements and the data to
which they apply may also be different for example, why retain operating system files for 7
years? For this reason, requirements like these should be separated.
IBM Tivoli Storage Manager overview
IBM Tivoli Storage Manager is implemented as a client server software application, consisting
of a IBM Tivoli Storage Manager server software component, IBM Tivoli Storage Manager
Backup/Archive client, the IBM Tivoli Storage Manager storage agent, and other
complementary Tivoli and vendor software products. Figure 2 shows the main components of
IBM Tivoli Storage Manager.

IBM Tivoli Storage Manager: A Technical Introduction 7
Figure 2 IBM Tivoli Storage Manager architecture
The IBM Tivoli Storage Manager serverprovides a secure environment, including automation,
reporting and monitoring functions, for the storage of client data. It also provides the storage
management policies and maintains all object inventory information to allow it to manage this
data in the most effective way. The IBM Tivoli Storage Manager Backup/Archive client,
IBM Tivoli Storage Manager storage agent, and complementary products implement data
management functions such as data backup and recovery, archival, space management, or
disaster recovery.
The client software can run on different systems, including laptop computers, PCs,
workstations, or server systems. The client and server software can also be installed on the
same system for a local backup solution. The storage agent software in conjunction with the
server software enables the implementation of LAN-free backup solutions exploiting the SAN
infrastructure. It is also possible to define server hierarchies or multiple peer-to-peer servers
in order to provide a multi-layer storage management solution or an electronic vaulting
solution.

8 IBM Tivoli Storage Manager: A Technical Introduction
IBM Tivoli Storage Manager server
One of the principal architectural components of the IBM Tivoli Storage Manager server is its
in-built relational database. The Tivoli Storage Manager database was especially designed for
the task of managing data, and it implements zero-touch administration. All policy information,
logging, authentication and security, media management and object inventory is managed
through this database. Most of the fields are externalized through Tivoli Storage Manager
high level administration commands, SQL SELECT statements or for reporting purposes, byusing an ODBC driver. Obviously, this database is fully protected with software mirroring,
roll-forward capability and with its own management and online backup and restore functions.
For storing the managed data, the Tivoli Storage Manager server manages a storage
repository. The storage repository can be implemented using any combination of supported
media magnetic or optical disk, tape, and robotic storage devices, which are locally
connected to the server system or which are accessible through a SAN. To exploit SAN
technology, the Tivoli Storage Manager server has features implemented to dynamically
share SAN connected automated tape library systems among multiple Tivoli Storage
Manager servers, as well as provide (as an option), LAN-free and server-free backup.
The Tivoli Storage Manager server provides built-in device drivers for more than 300 different
device types from every major manufacturer. It is also able to utilize operating system devicedrivers and external library manager software such as the Windows 2000 Removable Storage
Manager (RSM).
Within the storage repository the devices can operate stand-alone or can be linked together
to form one or more storage hierarchies. The storage hierarchyis not limited in the number of
levels and can also span over multiple servers using so-called virtual volumes. See Storage
and device concepts on page 19 for storage management functions available for the storage
repository.
IBM Tivoli Storage Manager Backup/Archive client
Data is sent to the IBM Tivoli Storage Manager server using the IBM Tivoli Storage ManagerBackup/Archive client and complementary Tivoli and non-IBM/Tivoli products. These
products work together with the Tivoli Storage Manager server base product to ensure that
the data you need to store is managed as defined.The Tivoli Storage Manager
Backup/Archive client, included with the server, provides the operational backup and archival
function. The client implements the patented progressive backup methodology, adaptive
sub-file backup technologyand unique record retention methods, as described in Backup
and archival concepts on page 15.
The Backup/Archive clients are implemented as multi-session clients, which means that they
are able to exploit the multi-threading capabilities of modern operating systems. This enables
the running of backup and archive operations in parallel to maximize the throughput to the
server system.
Depending on the client platform, the Backup/Archive client may provide a graphical,
command line or Web user interface (see Figure 3).

IBM Tivoli Storage Manager: A Technical Introduction 9
Figure 3 Backup/Archive client user interfaces
8/9/2019 IBM Tivoli Storage Manager a Technical Introduction
10/36
10 IBM Tivoli Storage Manager: A Technical Introduction
Many platforms provide all three interfaces. The command line interface is useful for
experienced users and allows generation of backup or restore scripts for scheduled
execution. The graphical interface is designed for ease of use for the end user for ad hoc
backups and restores. The Web client is especially useful for those clients, such as NetWare,
where no native GUI is available, or for performing remote backup/restore operations, for
example in a helpdesk environment.
Some clients (including some UNIX variants and Microsoft platforms) use a new plug-in
architecture to implement an image backup feature for raw device backup. This allows you to
back up and recover data stored in raw (that is, not a filesystem) volumes. It also provides an
additional method to make point-in-time backups of entire filesystems as single objects
(image backup) and recover them in conjunction with data backed up by using the
progressive backup methodology.
IBM Tivoli Storage Manager storage agent
The IBM Tivoli Storage Manager storage agent supports LAN-free backup solutions using a
SAN infrastructure. The storage agent dynamically shares SAN connected tape libraries and
disks with the Tivoli Storage Manager server, and it has the ability to write and read client
data directly to and from server-owned storage media.
The storage agent receives data objects via the Tivoli Storage Manager API (as discussed in
IBM Tivoli Storage Manager externalized interfaces on page 12) and communicates with the
Tivoli Storage Manager server over the LAN using TCP/IP to exchange control information
and meta-data about the objects being backed up. The data movement itself utilizes the
LAN-free path over the SAN to write directly to the storage media. Thus the data movement is
removed from both the LAN and the Tivoli Storage Manager server processor for potentially
greater scalability.
The storage agent is available for selected Backup/Archive clients as well as for backing up
popular databases and applications such as MS SQL-Server, MS Exchange, Oracle, DB2,
R/3 and Lotus Domino.
Server-free data movement
IBM Tivoli Storage Manager allows clients to directly back up and restore filesystem images
between disk storage and tape devices accessible over a SAN. This server-free data
movement is handled on behalf of the Tivoli Storage Manager server by an outboard data
mover, such as the IBM SAN Data Gateway. The data mover must be able to execute the
SCSI-3 extended copy command. Server-free data movers must have addressability to all the
devices involved, which include disk and tape drives. The devices may be attached to the
SAN through either direct Fibre-Attach or SCSI devices connected to a data mover.
Server-free data movement is supported for Windows platforms (server and client) at the time
of writing.
Unlike traditional LAN and LAN-free backups and restores, neither the Tivoli StorageManager server or client is in the data path. Instead, the data mover handles and moves the
data for backup and restore. In this way, backup and restore operations do not require
resources from client or server processors or from the LAN. Because it will not be copying
data, the Tivoli Storage Manager server can potentially handle more concurrent client
connections and server operations. In addition, the Tivoli Storage Manager client, since it
does not have to read and send data to the server, can handle a greater application load.

IBM Tivoli Storage Manager administration
For the central administration of one or more server instances, IBM Tivoli Storage Manager
provides command line or java-based administration interfaces (see Figure 4), also called
administration clients.
Figure 4 IBM Tivoli Storage Manager administration interfaces
Using the unique enterprise administrationfeature it is possible to configure, monitor and
manage all server and client instances from one administrative interface, known as the
enterprise console. It includes:
Enterprise configuration
Administrative command routing
Central event logging functions
8/9/2019 IBM Tivoli Storage Manager a Technical Introduction
12/36
12 IBM Tivoli Storage Manager: A Technical Introduction
The enterprise configuration allows Tivoli Storage Manager server configurations to be
defined centrally by an administrator and then propagated to other servers. This significantly
simplifies the configuration and management of multiple servers in an enterprise.
Administrative command routing allows administrators to issue commands from one Tivoli
Storage Manager server and route them to other target servers. The commands are executed
on the target servers, and the command output is returned and formatted on the server where
the command was issued.
In an enterprise environment with multiple Tivoli Storage Manager servers, client and server
events can be logged to a central management server through server-to-server
communications, thereby enabling centralized event management and automation.
IBM Tivoli Storage Manager externalized interfaces
IBM Tivoli Storage Manager provides a data management Application Programming Interface
(API), which can be used to implement application clientsto integrate popular business
applications, such as databases or groupware applications. The API also adheres to an open
standard (XBSA) and is published to allow customers or vendors to implement specialized or
custom clients for particular data management needs or non-standard computingenvironments. In general, we distinguish between IBM Tivoli Storage Manager products for
Applicationssoftware products and the API exploitation through vendor applications.
The IBM Tivoli Storage Manager products are separate program products delivered by IBM to
connect business applications, via the Tivoli Storage Manager API to the server. These
products are IBM Tivoli Storage Manager for Databases, Mail, ERP, Hardware, and
Application servers. Applications such as Oracle, Lotus Notes and Domino, Microsoft
Exchange, and Microsoft SQL server, provide their own backup and restore or storage
management tools. IBM Tivoli Data Protection product strategy is to interface to these tools to
provide backup and restore facilities and functions for these applications. Tivoli Data
Protection program products can also exploit the special features of IBM's Enterprise Storage
Server within an IBM Tivoli Storage Manager based storage management solution. For more
information, see Additional application and hardware support on page 30.
Alternatively, some vendor applications exploit the Tivoli Storage Manager data management
API by integrating it into their software product itself to implement new data management
functions, or to provide backup and archival functionality on additional system platforms.
Some examples are IBM CommonStore for R/3, Lotus Domino, and Microsoft Exchange data
archival, IBM BRMS/400 to provide an AS/400 backup solution, and SSSI Archive Backup
Client for OpenVMS data backup and recovery. IBM's DB2/UDB also works with a direct
connection to the IBM Tivoli Storage Manager API. Non-IBM/Tivoli products such as Veritas
Backup Exec also can use the API to manage backup data with an IBM Tivoli Storage
Manager server.
In addition to the externalized interfaces to the server database as described in IBM Tivoli
Storage Manager server on page 8, IBM Tivoli Storage Manager offers multiple interfaces forevent logging, reporting and monitoring the data management environment. All of the
activities of the Tivoli Storage Manager server and client are logged in the server database,
and they can also be sent for reporting and monitoring purposes to external event receivers
using the event filtermechanism. Potential event receivers are the Tivoli Enterprise
framework, SNMP based systems management software packages (such as IBM Tivoli
NetView), the Windows event log, and user written applications.
To integrate IBM Tivoli Storage Manager storage management with external library
management applications, IBM Tivoli Storage Manager offers an external library manager
interface. Using this interface, it is possible to integrate the Tivoli Storage Manager server into
8/9/2019 IBM Tivoli Storage Manager a Technical Introduction

third-party storage management environments. One example of this is for sharing STK tape
libraries using the ACSLS program. You can dynamically share tape drives installed in STK
libraries between multiple Tivoli Storage Manager servers using the EDT-DistribuTAPE
software from Gresham software. More information on this product is available at the Web
site:
http://www.greshamstorage.com/storage/products/distributape.html
IBM Tivoli Storage Manager supported environments
IBM Tivoli Storage Manager server and client software is available on many different
operating system platforms and can exploit different communication protocols. Figure 5
summarizes the supported environments at the time of writing.

Base concepts
This section gives a high level introduction to the base data and storage management
paradigms used by IBM Tivoli Storage Manager to implement its functionality. We will cover
data protection or backup, record retention or archival, storage management, policy, and
security.
Backup and archival concepts
Backup, in IBM Tivoli Storage Manager terms, means the creation of an additional copy of a
data object to be used for operational recovery. As already mentioned, the selection of data
objects to be backed-up needs to be done carefully to ensure that, when restored, the data is
still usable. A data object can be a file, a part of a file, a directory or a user defined data object
like a database table. The backup version of this data object is stored separately in the IBM
Tivoli Storage Manager server storage repository. Potentially, you can make several backup
versions of the data, each version at a different point-in-time. These versions are closely tied
together and related to the original object as a group of backups, and Tivoli Storage Manager
manages the retention of these objects in a consistent way.
If the original data object is corrupted or lost on the client system, restoreis the process of
sending a backup version of the data from the server back to the client. Typically, the most
current version of the data is normally restored, so Tivoli Storage Manager selects this as the
default, but you can choose to restore from any of the existing backup versions. The number
and retention period of backup versions is controlled by server policy definitions. Old (extra)

backup versions are automatically deleted as new versions are created, if the number of
versions stored exceeds the defined limit, or may be deleted after a certain period of time.
Figure 6 shows how policy definitions work with Tivoli Storage Manager. In this case, we have
specified to keep a maximum of 6 backup versions of a particular file. The files is backed up
via normal daily backup operations each day that it changes. The most recently backed up file
version is designated the active backup. All other versions are inactive backups. Tivoli
Storage Manager automatically deletes inactive backups when the total number of backup
versions stored exceeds the policy limit. In this case, on day 8, the oldest inactive file version
(which is actually the file as backed up on day 1) is expired so that at all times, a maximum of
6 backup versions is retained. Tivoli Storage Manager policy definitions also include these
parameters separately for files which are deleted from the client.
Figure 6 IBM Tivoli Storage Manager sample policy
For file level based backup, the main difference from many other backup applications is that
Tivoli Storage Manager uses the progressive backup methodology. As shown in Figure 7,
after the first complete backup,IBM Tivoli Storage Manager then operates with incremental
backups only. As a consequence, only those files that are new or that have changed since the
last backup will be backed up.
IBM Tivoli Storage Manager's file level progressive backup methodology, in comparison with
other methods like Full+Incremental or Full+Differential backup schemes, significantly
reduces the amount of data being copied and managed, and prevents unnecessary backups
of unchanged data to reduce and consolidate the recovery tape-set. As a result, IBM Tivoli
Storage Manager offers faster recovery by not restoring multiple versions of the same file,
only the data that is actually needed.

Figure 7 Progressive Backup Methodology vs. other backup schemes
The reorganization of the physical storage media to store each clients data physically
together on a small number of media in order to provide faster access in the case of a
complete system recovery is done transparently to the client, and is completely automated
on the server using data meta information stored in the server database.
IBM Tivoli Storage Managers adaptive sub-file backup technologyimplements anotherpowerful method to further reduce the amount of data transferred from the client to the server
system. This method enables the backup-archive client (Web client, command line, and GUI)
to back up only the changed portion of a file, either on a byte or block level, instead of
transferring the whole file to the server every time.This feature helps to overcome bandwidth
limitations of the network link, especially for mobile or remote client systems. Figure 8 shows
how this feature works.

Figure 8 Adaptive sub-file backup
At any point in time, IBM Tivoli Storage Manager allows the creation of a complete set of
client files (backup set) on the server system using the most recent backup versions stored in
the server storage repository. Backup sets, as shown in Figure 9, can be used to retain a
snapshot of all client files for a longer period of time (Instant Archive) or for LAN-free recovery
of a client system by copying this backup set onto portable media and restoring them locally
(Rapid Recovery).

IBM Tivoli Storage Manager: A Technical Introduction 19
Figure 9 Tivoli Storage Manager Backup set
Archivewith IBM Tivoli Storage Manager means creating a copy of a file as a separate object
in the storage repository to be retained for a specific period of time. Typically you would use
this function to create an additional copy of data to be saved for historical purposes, and
therefore, special consideration should be given to ensure that the data format is not
dependent on anything. Vital records (data that must be kept for legal or other business
reasons) are likely candidates for the archive process. You can specify to delete the original
copy of the data on the source system once the archive copy is created on the server. In thisway, you can use archiveto make additional space available on the Tivoli Storage Manager
client system. However, archiveshould not be thought of as a complete space management
function, because transparent automatic recall is not available.
You can gain access to archived data by using retrieveto return it to the Backup/Archive
client. To locate the archived data within the storage repository, Tivoli Storage Manager allows
you to add a description to the data and to form archive packagesof related files. You can
then use this description field to search the server database for matching packages, to
determine which data to retrieve.
Therefore, the difference between backupand archiveis that backup creates and controls
multiple backup versions that are directly attached to the original client file; whereas archive
creates an additional stored object that is normally kept for a specific period of time, as in thecase of vital records.
Storage and device concepts
All IBM Tivoli Storage Manager-managed client data is stored in the IBM Tivoli Storage
Manager storage repository, which consists of pools of like storage devices, such as disk,
tape, or optical devices. The storage repository is controlled by the server, which uses its own
model of storage to view, classify, and control these storage devices, and to implement the
storage management functionality (see Figure 10).

Figure 10 IBM Tivoli Storage Manager storage management concept
The main difference between the storage management approach of IBM Tivoli Storage
Manager and other commonly used systems is that IBM Tivoli Storage Manager storage
management concentrates on managing data objectsas they exist in the storage pools,
rather than just the backup tapes as a whole. Data objects can be sub-file components, files,
directories or raw logical volumes that are backed up from the client systems; they can be
objects like tables or records from database applications, or simply a block of data that a
client system wants to store on the server storage. Each object has an associated
management policy bound to it which defines what IBM Tivoli Storage Manager does withthat object.
To store these data objects on storage devices and to implement storage management
functions, IBM Tivoli Storage Manager uses logical definitions to classify the available
physical storage resources. Most important is the logical entity called a storage pool which
describes a storage resource for one single type of media; for example, a disk partition or a
set of tape cartridges. Storage pools are the place where data objects are stored.
A storage pool is built up from one or more storage pool volumes. For example, in the case of
a tape storage pool, this would be a single physical tape cartridge. To describe how IBM Tivoli
Storage Manager can access those physical volumes to place the data objects on them, IBM
Tivoli Storage Manager uses a logical entity called a device class. A device class is
connected to a storage pool and specifies how the server gains access to volumes of thisstorage pool.
IBM Tivoli Storage Manager organizes storage pools in one or more hierarchical structures.
This storage hierarchycan span over multiple server instances and is used to implement
management functions to migratedata objects, automatically and transparently to the client,
from one storage hierarchy level to another; or in other words, from one storage device to
another. This function may be used, for example, to store backup data (for performance
reasons) onto an IBM Tivoli Storage Manager server disk space before moving the data to
tape cartridges. The actual location of all data objects at all times is automatically tracked
within the server database.

Policy concepts
A data storage management environment consists of three basic types of resources: client
systems, rules, and data. The client systems contain the data to be managed, and the rules
specify how the management must occur; for example, in the case of backup, how many
versions should be kept, where they should be stored, and so on.
IBM Tivoli Storage Manager policies define the relationships between these three resources.
Figure 13 illustrates this policy relationship. Depending on your actual needs for managing
your enterprise data, these policies can be very simple or very complex.

Figure 13 Tivoli Storage Manager policy relationships and resources
IBM Tivoli Storage Manager has certain logical entities that group and organize the storage
resources and define relationships between them. Client systems, or nodesin Tivoli Storage
Manager terminology, are grouped together with other nodes with common storage
management requirements, into a Policy Domain.
The Policy Domain contains a logical structure called a Policy Set. A Policy Set contains andhelps to manage a collection of storage management rules for different storage management
activities. The rules are stored, within the Policy Set, in one or more Management Classes. A
Management Class contains the rule descriptions (actually stored in entities called Copy
Groups), which are linked to the stored data objects. The rules are really just a set of storage
management parameters, such as number of stored copies, retention period, storage media,
and so on. When a data object is linked to particular rules, it is said to be bound to the
management class that contains those rules.
Another way to look at the components that make up a policy is to consider them in the
hierarchical fashion in which they are defined. Consider the policy domain at the top,
containing at least one policy set which contains many management classes. Themanagement classes contain the copy groups and the storage management parameters and
it is the management classes that the Tivoli Storage Manager client can use to select how
particular data objects are to be stored.

A good practice, when designing a Tivoli Storage Manager backup policy, is to consider using
eitherthe number of versions orthe retention period. As mentioned above, Tivoli Storage
Managers backups are expired based on whichever parameter is matched first (versions ortime) so, in order to achieve a consistent restore capability (that is, restore to one of X
previous versions orrestore to any point of backup within Y days) think carefully about thevalues you use.
Security concepts
The storage repository of IBM Tivoli Storage Manager is the place where all the data of an
enterprise is stored and managed. Clearly therefore, security is a key aspect of Tivoli Storage
Manager. To ensure that only the owning cl ient or an authorized party can gain access to data
objects, Tivoli Storage Manager implements, for authentication purposes, a mutual suspicionalgorithm, which is similar to the methods used by Kerberos authentication.
Whenever a client (backup/archive or administrative) communicates with the server, an
authentication has to take place. This authentication contains both-sidesverification, which
means that the client has to authenticate itself to the server, and the server has to
authenticate itself to the client before any data objects are exchanged.
To do this, all clients have a password and a userid, which is stored at the server side as well
as at the client side. In the authentication dialog these passwords are used to encrypt the
communication. The passwords are not sent over the network, to prevent hackers from
intercepting them, and a new key is used for each encryption. A communication session will
be established only if both sides are able to decrypt the dialog. If the communication has
ended, or if a timeout period without activity is passed, the session will be automatically
terminated and a new authentication will be necessary.
In mobile computing environments, files are often sent to the Tivoli Storage Manager server
system using a modem connection, and so they are exposed to the security hazards of public
telephone lines. The Backup/Archive client optionally provides (in addition to the end-point
security concept outlined above) a data encryption function, which allows for encrypting data
before it is sent to the server, and which protects the data while it is being transferred to the
server and also while it resides in the storage repository.

IBM Tivoli Storage Manager complementary products
IBM Tivoli Storage Manager complementary products use the Tivoli Storage Manager server
as a backbone product to implement additional data and storage management functions. In
the following section we introduce IBM Tivoli Space Manager for hierarchical space
management, IBM Tivoli Disaster Recovery Manager as an enterprise-wide solution for
disaster recovery, and IBM Tivoli Decision Support for Storage Management Analysis for acomprehensive reporting and monitoring solution to plan the growth and collect vital
management information for an efficient enterprise data management deployment.
IBM Tivoli Space Manager
IBM Tivoli Space Manager uses the Tivoli Storage Manager framework services together with
the industry standard Data Management Application Programming Interface (DMAPI)to
deliver a fully integrated solution for open systems Hierarchical Space Management (HSM).
IBM Tivoli Space Manager provides an HSM client, which interfaces with DMAPI and
implements the functionality outlined in Figure 14 for certain Tivoli Storage Manager clients.
Figure 14 IBM Tivoli Space Manager for HSM
IBM Tivoli Space Manager maximizes usage of existing storage resources by transparently
migrating data from client hard drives to the Tivoli Storage Manager storage repository based
on size and age criteria. When the migrated data is accessed, IBM Tivoli Space Manager
transparently recalls it back onto the local disk. The migration of files and the management of
migrated files is controlled by policies. Manual (user controlled) migration and recall is also
possible.
IBM Tivoli Space Managers HSM function is fully integrated with Tivoli Storage Manager
operational backup, so that if a client requests to back up a file which has already been
migrated to the server, it will be copied to a backup storage pool internally, thereby avoiding a
client data recall.
The HSM function through IBM Tivoli Space Manager is available for AIX and Solaris clients.

Disaster Recovery Manager
Disaster Recovery Manager (DRM) is a feature of the IBM Tivoli Storage Manager Extended
Edition. and coordinates and automates the process of recovering from a disaster. It provides
for offsite media management, automated restore of the Tivoli Storage Manager server and
managed client recovery. It complements the already implemented robust protection features
of Tivoli Storage Manager and automates many already facilitated protection functions.
DRM automatically captures information required to recover the Tivoli Storage Manager
server after a disaster. It assists in preparing a plan that allows recovery in the most expedient
manner. This disaster recovery plancontains information, scripts, and procedures needed to
automate server restoration, and helps ensure quick recovery of your data after a disaster.
DRM also manages and tracks the movement of off-site media to reduce the time required to
recover in the event of a disaster. It is able to track media that are stored on-site, in-transit, or
off-site in a vault, no matter whether it is a manual or electronic vault, so your data can be
easily located if disaster strikes. The DRM media cycle is shown in Figure 15.
Figure 15 Disaster Recovery Manager offsite media tracking cycle
Client recovery information can also be captured by DRM. This information can be used to
assist with identifying what clients need to be recovered, in what order, and what is requiredto recover them, including data and media that is not managed by Tivoli Storage Manager.
NDMP
IBM Tivoli Storage Manager Extended Edition provides support for certain Network Attached
Storage (NAS) appliances using Network Data Management Protocol (NDMP) to perform
high-performance, scalable backups and restores at the volume and file level. These backups
and restores minimize network traffic by transferring data independently of the Tivoli Storage

Manager client and server where available. NDMP support enables both full and differential
file system image backups and restores of Network Appliance file servers with operating
system Data ONTAP 6.1.1 or higher. Multiple backup and restore operations can be
performed simultaneously.
NDMP support is implemented through a combination of the Tivoli Storage Manager
Extended Edition server and Backup/Archive client code. No additional code need be
installed on the server, client, or NAS appliance. during backup and restore operations, data
flows directly between the NAS appliance and the tape drive. Either a SCSI-attached tape
device local to the NAS appliance, or a SAN-attached SCSI or ACSLS device, shared with the
Tivoli Storage Manager server can be used.
Bare metal recovery
Bare metal recovery (BMR) is the ability to restore a system completely, assuming that all
data and configuration information has been erased from the hard disk. There are a number
of products and techniques which can be used to provide BMR in association with IBM Tivoli
Storage Manager product capabilities.
For Windows clients, BMR can be achieved using the regular Backup/Archive client. The
basic technique is to re-install the operating system and then restore all additional files and
configuration information using the Tivoli Storage Manager client. An alternative method is to
use a third-party volume imaging product to capture the complete system information in a
single object. Various third-party products can or will offer the capability to store the captured
volume images on the Tivoli Storage Manager server.
For UNIX clients, a re-install of the OS together with Backup/Archive client restore of
additional data provides a solution. In the case of AIX, IBM Tivoli Storage Manager for
System Backup and Recovery (also known as SysBack) provides a complete backup and
restore solution including full system (installation) images, volume groups, raw logical
volumes and filesystems. See IBM Tivoli Storage Manager for System Backup and Restore
on page 34 for more information.
A more detailed discussion of bare metal recovery techniques on various platforms is
contained in the redbook Disaster Recovery Strategies with Tivoli Storage Management,
SG24-6844.
IBM Tivoli Decision Support for Storage Management Analysis
IBM Tivoli Decision Support for Storage Management Analysis uses the framework services
of IBM Tivoli Decision Support to deliver important decision-making information about your
enterprise data management deployment.
IBM Tivoli Decision Support is a stand-alone product that provides a ready-to-use view intothe wealth of data gathered by Tivoli enterprise products. The product consolidates this data
and transforms it into accessible IT business-relevant information. This information, presented
in a variety of graphical formats, can be viewed interactively (slice, dice, drill down, drill
through) and posted on a URL. IBM Tivoli Decision Support provides insight and the ability to
better answer IT business-relevant questions. IBM Tivoli Decision Support is available on
Windows NT and Windows 2000.
The IBM Tivoli Decision Support Discovery Guides are a set of best practices guides provided
for various applications. To use these guides, IBM Tivoli Decision Support has to be installed
8/9/2019 IBM Tivoli Storage Manager a Technical Introduction
28/36
28 IBM Tivoli Storage Manager: A Technical Introduction
and available. The Tivoli Decision Support for Storage Management Analysis is the guide
used to produce the following analyses:
Storage Event Analysis
Storage Performance Analysis
Storage Capacity Analysis
A typical IBM Tivoli Decision Support for Storage Management Analysis graph is shown inFigure 16.
Figure 16 IBM Tivoli Decision Support for Storage Management Analysis
The information used by the guide is obtained directly from the Tivoli Storage Manager server
with the use of the ODBC interface. The information is then transferred to a relational
database, as required by Tivoli Decision Support for Storage Management Analysis, such as
DB2, MS SQL-Server, and Oracle. The database can reside on the same system as IBM
Tivoli Storage Manager or IBM Tivoli Decision Support or on a separate system. Thedatabase is used for queries to generate the IBM Tivoli Decision Support reports.
Tivoli SANergy
Tivoli SANergy is a product which allows filesystems to be shared across a Storage Area
Network. SANergy provides a function, known as a MetaData Controller (MDC), which owns
the filesystem. Any SANergy client may gain access to that storage across the SAN by first
requesting the MDC for permission, and for the location of the data. After the MDC
8/9/2019 IBM Tivoli Storage Manager a Technical Introduction
29/36
IBM Tivoli Storage Manager: A Technical Introduction 29
completes the request, the client accesses the volumes by normal NFS or CIFS methods;
however, the data blocks are read and written using the SAN, rather than the LAN
communication path.
This function can be exploited by Tivoli Storage Manager to provide LAN-Free backups to
storage pool volumes defined as files on SANergy managed disk. This works in a similar way
to the base product when it provides LAN-Free backups to tape volumes, in that metadata
about the client data is sent across the LAN to the Tivoli Storage Manager server but the data
itself travels across the SAN.
Figure 17 shows the flow of data and metadata when using SANergy to share a volume for
LAN-Free backups. Using this function not only gives the advantages of LAN-Free backup,
reducing the load on the LAN, but also helps reduce the limitation of the number of available
tape drives on LAN-Free capability for backup. Data could also be restored using LAN-Free
either directly from tape or by first using commands within the IBM Tivoli Storage Manager
server to move the data back to SANergy managed disk.

Additional application and hardware support
A number of additional products are available which provide additional support for particular
applications and disk storage systems. These products, previously known as Tivoli Data
Protection modules, are a group of solutions integrated with IBM Tivoli Storage Manager,
which protect data used by business applications. They are interface programs that link
between a storage management API provided by the vendor application, and the IBM TivoliStorage Manager data management API. Typical applications providing such interfaces are
databases and groupware applications, such as Lotus Notes or Microsoft Exchange.
Figure 18 shows a typical architecture and data flow of an IBM Tivoli Storage Manager
application-specific solution.
Figure 18 IBM Tivoli Storage Manager for Applications architecture
The function of these solutions is to receive application backup and restore requests and to
translate them into Tivoli Storage Manager backups and restores. The activity is always
initiated from the application and uses application-provided system calls to provide backup
and restore services, thus implementing the intelligence and function of the
application-provided backup interface. This means that backups or restores can be done
while the application is on line.
However, in 7x24 production environments, even the ability to do an online backup of that
application data may not be the most desirable option. Certain intelligent disk subsystems
(such as IBM TotalStorage Enterprise Storage Server) implement features which allow for
creating an instantcopy of all the application data on different physical volumes that areaccessible by an alternate (backup) system, with nearly no interruptions. IBM Tivoli Storage
Manager for Hardware interfaces with these features and integrate them into a complete IBM
Tivoli Storage Manager data management solution to provide backup capabilities with as little
impact on production performance as possible.
Table 4 shows the available products for application and hardware support from Tivoli,
including the supported platforms, the operating system level, and the application level they
cover, at the time of publishing this paper. Please refer to the product Web sites for the most
