WDSF morphed into ADSTAR Distributed Storage Manager ( ADSM) and was re-branded Tivoli Storage Manager in 1999. WDSF's original purpose was to back up PC/DOS, OS/2, and AIX workstation data onto a VM/CMS (and later MVS) server. The first product that emerged was Workstation Data Save Facility ( WDSF).

TSM descended from a project done at IBM's Almaden Research Center around 1988 to back up VM/CMS systems. This product is part of the IBM Spectrum Software Defined Storage suite of products and is unrelated to the Tivoli Management Framework.

It enables backups and recovery for virtual, physical and cloud environments of all sizes. It is the flagship product in the IBM Spectrum Protect (Tivoli Storage Manager) family. IBM Spectrum Protect ( Tivoli Storage Manager) is a data protection platform that gives enterprises a single point of control and administration for backup and recovery.
