DFSMS Insights

What is DFSMS?

DFSMS (Data Facility Storage Management Subsystem) is an IBM mainframe (z/OS) storage management system. It automates and simplifies storage management tasks, optimizing storage utilization, data availability, and performance. DFSMS uses policies to automatically manage data placement, backup, recovery, and migration based on predefined criteria, which reduces manual intervention and improves overall storage efficiency.
