These projects aimed implementing the sysplex technology connecting two computer centres to implement an online real time backup. Using EMC2 and Sysplex technology a DR scenario was implemented enabling switching to the other computer centre within one hour in case of a disaster. Both technical implementation as well as procedures and organisational readiness were audited. These techniques are used within large banking environments and took a couple of years to be implemented. Design, implementation and tests were audited, as well as the entire project structure. During these projects the board was notice regarding the progress and results at several key moments.
