Backup in IBM Tivoli Storage Manager terms, means the creation of an additional copy of a data object to be used for operational recovery. 

 TSM Backup and Restore Process

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. The below Video demonstrates how to take a simple client file backup and restore process using TSM command-line and TSM B/A Client GUI. Same procedure can be used in most of the Operating Systems.

If the original data object is corrupted or lost on the client system, restore is 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.  The below Video demonstrates how to take a simple client file Archive and Retrieve process using TSM command-line and TSM B/A Client GUI. Same procedure can be used in most of the Operating Systems.

Tivoli Storage Manager Performance Tuning

Tivoli Storage Manager performance can be influenced by various tuning parameters. Tuning these functions for good performance requires diligence and expertise on the part of the implementer. Tuning Tivoli Storage Manager can be quite complex because of the many operating systems, network configurations and storage devices that Tivoli Storage Manager will support. It is the purpose of this tuning guide to provide tips and hints to ease the task of getting good performance for Tivoli Storage Manager operations.

Performance tuning for a single platform function is quite complex, but due to years of experience, it is generally well understood. Tivoli Storage Manager, however, functions in the client/server realm, supports many operating systems, works across networks, and accepts different communication protocols. Consequently, there are many more factors that affect performance. These factors can affect Tivoli Storage Manager performance significantly:
  • Average client file size
  • Percentage of files changed since last incremental backup
  • Percentage of bytes changed since last incremental backup
  • Client hardware (CPUs, RAM, disk drives, network adapters)
  • Client operating system
  • Client activity (non-Tivoli Storage Manager workload)
  • Server hardware (CPUs, RAM, disk drives, network adapters)
  • Server storage pool devices (disk, tape, optical)
  • Server operating system
  • Server activity (non-Tivoli Storage Manager workload)
  • Network hardware and configuration
  • Network utilization
  • Network reliability
  • Communication protocol
  • Communication protocol tuning
  • Final output repository type (disk, tape, optical

Tivoli Storage Manager Tuning Parameters

The following parameters are tunable on most Tivoli Storage Manager servers. Not all options are supported on all server platforms. Check the Administrators Reference for applicability to a particular platform. These parameters can all be changed in server options file (dsmserv.opt) or some can be changed with the server SETOPT command. For any changes made in the server options file, the server must be halted and then restarted for the changes to take effect.
