IBM totalstorage productivity center for replication for z/OS

Designing and implementing a business resilience (or disaster recovery) plan is a complex procedure for customers, and the impact of implementing an incorrect or incomplete plan can be significant. For some customers, being able to recover their data center functionality in a short period of time may be of the utmost importance; for others, recovering in a short period of time may be worthless if the data with which their database is restored is hours or days old. Also of importance is the impact to business-critical applications when copies of data are being made. This paper presents the IBM TotalStorage™ Productivity Center for Replication (TPC-R), a tool designed to help customers implement cost-effective data replication solutions for continuous availability and disaster recovery. We give an overview of TPC-R, describe recent enhancements to TPC-R that are available on all supported platforms (as well as those that are unique to the z/OS™ platform) and discuss the ways in which customers can exploit TPC-R to implement business resilience solutions, with a focus on the various trade-offs customers must consider when choosing between different storage replication technologies.
