IBM’s Tivoli Storage Manager is acclaimed as one of the most flexible backup software which is catering the high-end business professionals for quite a noted period of time. This potential backup tool was introduced in early 90s as Ad star Distributed storage Manager (ADSM) which was built with a focus on concepts of mainframe data storing management. This software mainly evolved from (WDSF) Workstation Data Safe Facility which was a backup tool for distributed network launched by IBM in late 80s.
Some of the valuable attributes of TSM backup software are hereby noted.
Advanced Incremental Backups
IBM’s advanced incremental configuration is one of unique areas of focus to consider. The fundamental concept behind these is to provide more backup options to ensure the protection and restoration of data in proper manner. In case of first time restoration of a file, all the copies are backed up. After that, only the files which are subsequently changed are only backed up. Hence, it helps one to reduce the level of data content which needs to transfer through the network. To do this, TSM mainly maintain a database to know about the objects it copies and moreover to know about:
- If a file is backed up earlier.
- To maintain point-in-time state information.
Backup Versions
TSM uses the backup object reasoning to maintain definite point-in-time data content. Compared to other incremental backup tools, TSM retains data on file versions and not on media or ‘jobs’ version. With each file to back up, there is active and inactive version of configuration. TSM retains a predefined number of versions to be accessed for a specified timeframe. Hence, effective and competent TSM products of premium quality offer proper data restoration management and ensure protection of information in a systematic manner.
Storage Pool Hierarchy
TSM backup software stores the backup objects in a number of storage pools. These backup objects are aimed to storage pools which are further associated with specific device classes. Storage pools use random access equipments or sequential access devices. Moreover, TSM support association of “server” devices with the storage pools means that the backup data can be migrated in a transparent manner from the local storage devices to remote TSM servers.
Crafted Line Interface
TSM backup software provides an inclusive (CLI) Command Line Interface which allows every single TSM backup, management, restore, reporting and monitoring operation to be conceived. Usually, a command line interface is available on both client’s monitor and TSM server.
TSM servers are potential enough to resist the craving process of a full backup and offer a specified backup which allow the selected files to backed up in cases of no further changes since last incremental backup of the files. To add, this proficient and highly potential TSM data backup tool provides adequate support to the high end professional for a proper data restoration framework.
