Administrator's Guide
Tivoli Storage Manager is an enterprise-wide storage management
application. It provides automated storage management services to
workstations, personal computers, and file servers from a variety of vendors,
with a variety of operating systems. Tivoli Storage Manager includes
the following components:
- Server
-
- Server program
- The server program provides backup, archive, and space management services
to the clients.
You can set up multiple servers in your enterprise network to balance
storage, processor, and network resources.
- Administrative interface
- The administrative interface allows administrators to control and monitor
server activities, define management policies for clients, and set up
schedules to provide services to clients at regular intervals.
Administrative interfaces available include a command-line administrative
client and a Web browser interface. Tivoli Storage Manager allows you
to manage and control multiple servers from a single interface that runs in a
Web browser.
- Server database and recovery log
- The Tivoli Storage Manager server uses a database to track
information about server storage, clients, client data, policy, and
schedules. 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.
- Server storage
- The server can write data to hard disk drives, disk arrays and
subsystems, stand-alone tape drives, tape libraries, and other forms of
random- and sequential-access storage. The media that the server uses
are grouped into storage pools. The storage devices can be
connected directly to the server, or connected via local area network (LAN) or
storage area network (SAN).
- Client Nodes
- A client node can be a workstation, a personal computer, a file server, a
network-attached storage (NAS) file server, or even another Tivoli Storage
Manager server. The client node has Tivoli Storage Manager client
software installed (except for NAS file servers using NDMP). A client
node is registered with the server.
- Backup-archive client
-
The backup-archive client allows users to maintain backup versions of files,
which they can restore if the original files are lost or damaged. Users
can also archive files for long-term storage and retrieve the archived files
when necessary. Users themselves or administrators can register
workstations and file servers as client nodes with a Tivoli Storage Manager
server.
The storage agent is an optional component that may also be
installed on a system that is a client node. The storage agent enables
LAN-free data movement for client operations.
- Application program interface (API)
-
The API allows you to enhance existing applications to use the backup,
archive, restore, and retrieve services that Tivoli Storage Manager
provides. Tivoli Storage Manager API clients can register as client
nodes with a Tivoli Storage Manager server.
Tivoli Storage Manager supports separately licensed, optional
products. These include:
- Tivoli Data Protection for applications (application clients)
-
Application clients allow users to perform online backups of data for
applications such as database programs. After the application program
initiates a backup or restore, the application client acts as the interface to
Tivoli Storage Manager. The Tivoli Storage Manager server then applies
its storage management functions to the data. The application client
can perform its functions while application users are working, with minimal
disruption.
- Tivoli Data Protection for NDMP
- The Tivoli Data Protection for NDMP product allows you to use Tivoli
Storage Manager with the Network Data Management Protocol (NDMP) to back up
and restore file systems stored on a network-attached storage (NAS) file
server. The data on the NAS file server is backed up to a tape
library. See Chapter 6, Setting Up Tivoli Data Protection for NDMP for more information.
- Tivoli Space Manager
-
Tivoli Space Manager provides space management services for workstations on
some platforms. Tivoli Space Manager automatically migrates files that
are less frequently used to server storage, freeing space on the
workstation. The migrated files are also called space-managed
files. Users can recall space-managed files automatically simply
by accessing them as they normally would from the workstation. Tivoli
Space Manager is also known as the hierarchical storage management (HSM)
client.
For information about supported operating systems for clients, see
the Tivoli Storage Manager Web site:
http://www.tivoli.com/support/storage_mgr/tivolimain.html
Client programs such as the backup-archive client and the HSM client
(space manager) are installed on systems that are connected through a LAN and
are registered as client nodes. From these client nodes, users can back
up, archive, or migrate files to the server.
The following sections present key concepts and information about Tivoli
Storage Manager. The sections describe how Tivoli Storage Manager
manages client files based on information provided in administrator-defined
policies, and manages devices and media based on information provided in
administrator-defined Tivoli Storage Manager storage objects.
The final section gives an overview of tasks for the administrator
of the server, including options for configuring the server and how to
maintain the server.
