Basic functions of TSM

TSM is a very comprehensive solution, which can provide enterprise-level storage data management functions. From the perspective of information life cycle, TSM can provide a series of functions such as data protection, data archiving, hierarchical storage and data destruction. Therefore, TSM is not only a data backup software, but also provides more data management functions on the basis of data backup. From the perspective of data management function, TSM mainly includes the following four functions:

Centralized data backup and recovery management

TSM storage management software can provide users with professional data backup functions and multi-level data backup, such as file system backup, application system backup, database backup, mail system backup, operating system backup and other different backup categories. TSM can support most mainstream operating system platforms and mainstream applications, and customize appropriate backup solutions for different users according to their needs. Because most users' storage data management needs are mainly concentrated on centralized backup, TSM is introduced as backup software to everyone. Therefore, this paper also mainly introduces the backup management function of TSM.

Professional data archiving management function

TSM storage management software provides professional file system data archiving function. TSM's data archiving function is based on TSM infrastructure, and there is no need to install other software modules, nor does it require users to pay separately. TSM provides an independent archiving strategy, which can specify different archiving retention times for different data objects and provide different options for local retention or deletion of files when archiving.

Efficient hierarchical storage function

TSM storage management software can provide professional hierarchical storage function of file system, and can use storage devices such as tapes as secondary storage of file system. Customize the policy, migrate infrequently accessed files from the file system of the server to the tape library managed by TSM, and keep a stub file locally. The whole process can be done automatically or manually. When an application system or administrator accesses a file, TSM can automatically migrate the file back to the local area in the background. The hierarchical storage function provided by TSM can greatly expand the effective space of hard disk.

Simplified disaster recovery management

TSM storage management software provides simplified disaster recovery management functions. TSM has built-in disaster recovery management module (DRM), which can standardize the process management of disaster recovery, including tracking and recycling of offline tapes, automatically setting and updating tape status, and providing configuration information and recovery scripts required for the whole recovery process, which can guide administrators to successfully complete the whole recovery process. TSM also provides a disaster recovery method for transmitting data through the network, which can transmit data from one TSM system to another TSM system through professional technology, thus completing data-level disaster recovery based on the network.
