Tivoli Storage Manager (TSM) is an
enterprise-wide storage management application for the network.
It provides automated storage management services to multivendor workstations,
personal computers, and local area network (LAN) file
servers. TSM includes the following components:
- Server
- Allows a server system to provide backup, archive, and space management
services to workstations. The server maintains a database and recovery
log for TSM resources, users, and user data.
The server controls the TSM server's storage, called storage
pools. These are groups of random and sequential access media that
store backed up, archived, and space-managed files.
You can set up multiple servers in your enterprise network to balance
storage, processor, and network resources. TSM allows you to manage and
control multiple servers from a single interface that runs in a web browser
(the enterprise console).
- Administrative client
- Allows administrators to control and monitor server activities, define
management policies for client files, and set up schedules to provide services
at regular intervals. Administrative functions are available from an
administrative client command line and from a web browser interface.
- Backup-archive client
- Allows users to maintain backup versions of their 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 or administrators can register workstations and
file servers as client nodes with an TSM server.
- Hierarchical storage management (HSM) client
- Provides space management services for workstations on some
platforms. TSM users can free workstation storage by migrating less
frequently used files to server storage. These migrated files are also
called space-managed files. Users can recall space-managed files automatically simply by
accessing them as they normally would.
- Application programming interface (API)
- Allows users to enhance existing applications with backup, archive,
restore, and retrieve services. When users install the TSM API client
on their workstations, they can register as client nodes with an TSM
server.
This chapter contains information to help you understand the messages
issued by the Tivoli Storage Manager (TSM):
- Server program
- Administrative client graphical user interface
- Administrative command line client
- Backup-archive client
- Space-management client
Messages can appear on the server console, the administrative client, an
operator terminal, the administrative graphical user interface, the
backup-archive client, or the space-management client.
TSM provides an activity log to help the administrator track server
activity and monitor the system.
The activity log contains messages generated by the server and is stored in
the database. To access the activity log from the administrative
graphical user interface, select the SERVER icon. The server
automatically deletes messages from the activity log after they have passed
the specified retention period. Any messages sent to the server console
are stored in the activity log. Examples of the types of messages
stored in the activity log include:
- When client sessions start or end
- When migration starts or ends
- When backed up files are expired from data storage
- Any output generated from background processes
