zDP is a mainframe Dell software solution providing continuous data protection for your mainframe data assets. Deployed on TimeFinder SnapVX, Dell’s new space efficient volume snap capability, your environment can increase the granularity of application recovery. Increasing granularity involves leveraging zDP’s three components; versioned data groups (VDG), snapsets, and Target Sets. To assist customers with zDP, the software includes the ability to manage, operate, and monitor your environment through JCL, ISPF, and SCF commands. These components working together provide seamless integration for your backups to use and leverage zDP.
