To safeguard the Group optimally against breakdowns, we chose in 2003 to store our data at two locations – a geographically dispersed parallel sysplex (GPDS). The two locations contain all the Bank’s systems and data, which are synchronously reflected. This means that we always have two identical sets of data and systems. If servers at one location cease to operate, the machinery at the other will automatically take over operations for the Bank.
In addition, the Group has selected to set up an emergency environment (G3), storing key business-critical systems and data. If an error knocks out the environment holding all the Bank’s systems and data, we can in the course of a few hours shift operation to our emergency environment. In this environment, vital customer and Bank systems can continue operation without any further delays. We test the disaster recovery service each year, where we close down one operational centre completely, allowing the other to take over operation. In addition, we test the emergency environment once every week, where we close down the entire primary production environment, so that only the key business-critical systems – e.g. Netbank, trading systems and the ATMs – continue operation.
