Tivoli storage management: Tivoli Tsm

Tivoli Tsm is an enterprise-wide Tivoli storage management application. It provides automated storage management services to workstations, personal computers, and file servers from various vendors, with various operating systems.

Tivoli storage management includes the following components: ServerServer program 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. The administrative interface allows administrators to control and monitor server activities, define Ibm Tsm management policies for clients, and set up schedules to provide services to clients at regular intervals.

Administrative interfaces include a command-line administrative client and a web-based interface that is called the Operations Center. With Tivoli storage management you can manage and control multiple servers from a single interface that runs in a web browser.

Server database and recovery log the Tivoli Tsm 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 scratchpad for the database, recording information about client and server actions while the actions are being performed.

The server Tivoli storage management can write data to hard disk drives, disk arrays and subsystems, stand-alone tape drives, tape libraries, and other forms of random-access 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 through a local area network (LAN) or a storage area network (SAN). Client NodesA client node can be a workstation, a personal computer, a file server, or even another Tivoli storage management. The client node has IBM Tsm Storage Manager client software that is installed and is registered with the server.

Network-attached storage (NAS) file servers can also be client nodes, but when you use NDMP, they do not have Tivoli storage management client software installed. Backup-archive clients 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 Tsm server.

The storage agent is an optional component that can also be installed on the same system as the client node. The storage agent enables LAN-free data movement for client operations and is supported on a number of operating systems.

Network-attached storage file server (by using NDMP)The server can use the Network Data Management Protocol (NDMP) to back up and restore file systems that are stored on network-attached storage (NAS) file server. The data on the NAS file server is backed up to a tape library.

The Tivoli Tsm software does not need to be installed on the NAS file server. A NAS file server can also be backed up over the LAN to a Tivoli storage management. For more information, including details about supported NAS file servers, see Using NDMP for operations with NAS file servers.

Application clientApplication clients allow users to initiate 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 management.

 

The Tivoli Tsm server then applies its storage management functions to the data. The application client can initiate its functions while application users are working, with minimal disruption.The following products provide application clients for use with the  IBM tsm or Tivoli Storage Manager server:

  • Tivoli storage management
  • Tivoli storage management for Enterprise Resource Planning
  • Tivoli Tsm for Mail
  • IBM Tsm

Application programming interface (API)The API can help you to enhance existing applications to use the backup, archive, restore, and retrieve services that Tivoli storage management provides. Tivoli tsm API clients can register as client nodes with a Tivoli Storage Manager server.

Tivoli storage management for Space ManagementTivoli Storage Manager for Space Management provides space management services for workstations on some operating systems. The space management function is essentially a more automated version of the archive. 

IBM tsm for Space Management 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 by accessing them as they normally would from the workstation. Tivoli Storage Manager for Space Management is also known as the space manager client or the hierarchical storage management (HSM) client.

HSM for WindowsThe Tivoli storage management for HSM for Windows client provides hierarchical storage management (HSM) for Windows NTFS file systems. HSM is a data storage system that automatically moves data between high-cost and low-cost storage media.

High-speed storage devices are more expensive per byte stored than slower devices, such as magnetic tape drives.

While it would be ideal to have all data available on high-speed devices all the time, this is prohibitively expensive for many organizations. HSM is available to store data on slower devices, and then copy data to faster disk drives only when needed.

For information about supported operating systems for clients, see the IBM Tivoli Storage Manager website at IBM

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 that 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 management. The sections describe how Tivoli Storage Manager manages client files that are based on information that is provided in administrator-defined policies and manages devices and media that are based on information that is provided in administrator-defined Tivoli Tsm 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.

 

  • How client data is stored
    Tivoli storage management policies are rules that determine how the client data is stored and managed. The rules include where the data is initially stored, how many backup versions are kept, how long archive copies are kept, and more.
  • How the server manages the storage of Tivoli Tsm.
    Through the server, you manage the devices and media used to store client data. The server integrates the management of storage with the policies that you define for managing client data.
