IBM's Tivoli Storage Manager (TSM) is a full-featured and flexible backup and recovery solution and the core of IBM's Data Storage Management Solution set. TSM delivers plenty of options and modules, but integrates few of them into the core offering.
History of IBM Tivoli Storage Manager
TSM was originally developed by IBM in 1993 as Adstar Distributed Storage Manager (ADSM). After acquiring Tivoli in 1996, IBM moved ADSM under the Tivoli umbrella, but the Adstar brand wasn't dropped until 1999. IBM's main interest in developing Storage Manager was the ability to back up remote locations as well as the local office. This has become a common feature among backup vendors, and TSM still supports connection via Internet, WAN, LAN, and SAN.
