The GDPS family of System z Business Continuity solutions consists of two major offering
categories, and each category has several subofferings. Each GDPS solution is delivered
through IBM Global Services, and is specifically tailored to fit a specific set of client recovery
needs, budgetary requirements, physical distance and infrastructure, and other factors.
The three major categories of GDPS solutions are:

Peer-to-Peer Remote Copy (PPRC).

known as Extended Remote Copy (XRC).
