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 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 IBM’s 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 tradeoffs customers must consider when choosing between different storage replication technologies.
