What is Virtual Tape Systems?

A Virtual Tape System (VTS), also known as a Virtual Tape Library (VTL), is a data storage virtualization technology that emulates a magnetic tape library using disk-based storage. It is commonly used for data backup and archiving, providing faster backup and restore times compared to physical tape. VTS can also improve data management and reduce storage costs.

Virtual Tape Systems Competitor Technologies

DASD

Direct Access Storage Devices (DASD) offer direct online storage, a contrasting data storage model to virtual tape systems which emulate tape drives for data archival and backup. DASD, generally offering faster access but higher cost, represents an alternative solution for data storage and retrieval, thus competing with VTS in some usage scenarios.
