ADSTAR Distributed Storage Management (ADSM) is a collective term for IBM's family of high-end software that helps a customer manage the storage devices (such as mainframe storage, PC disk drives, and Zip drives) that are scattered around the company.
ADSM helps medium and large companies automatically back up the business information in all of the storage devices throughout the enterprise. ADSM software works with a variety of database formats, including those made by IBM competitors.
The basic premise behind ADSM is to allow customers to view and manage storage as a single comprehensive endeavor. The idea is to let customers back up on an enterprise level, instead of having to save all the data residing in all the PCs, networks and other machines throughout a company at each individual location.
IBM is no longer actively selling ADSM software. Instead, IBM and its Tivoli subsidiary are selling Tivoli Storage Manager software as the ADSM successor.
