By D en n y y ost tape backup, zDP provides 144 times the granularity to recover from a situation that could have otherwise been detrimental or fatal to your business. zDP provides a granular level of protection for your mainframe assets so that a processing error, malicious intent or human error may not cause a data center-wide outage. zDP Group (VDG) that defines the source volumes used for the point-in-time copies. These source volumes can be referred to by SYMM ID, z/OS device number, Dell EMC GNS group name or volume serial number. Once the customer starts the VDG through Dell EMCSCF address space, the snapshots taken of the source volumes defined in that VDG are referred as a “snapset.” … the responsibility of CIos has expanded beyond providing for rapid recovery from data center loss to ensuring rapid recovery from loss of data integrity. utilizes the concept of snapshots of Dell EMC VMAX source volumes that allow applications to restore data at a more granular level. This granularity provides point-in-time recovery for both database and non-database systems. With point-in-time copies, selectable recovery points and the ability to automate the backup process, users can elevate their data center and mission critical data management to a level of security never before possible. zDP executes within the Mainframe Enablers ResourcePak Base within a z/OS environment. The zDP application will automate the creation of consistent snapshots on a continuous basis, and they only record changed tracks so many snaps can be saved with minimal space usage. zDP uses a construct called the Versioned Data ZDP also supports the definition and validation of a set of volumes, called a Target Set, to which the snapsets can be linked to access the snapset data from a host. It is important to note that a Target Set does not need to be defined in order to build snapshots/snapsets. However, in order to use the data from a snapset you must link the snapset to the Target Set. Finally, while zDP runs, you can use the zDP VDG query commands to monitor and report on the zDP application.
