Disaster Recovery Models
OM-5.6.10
There are various disaster recovery models that can be adopted by licensees to handle prolonged disruptions. The traditional model is an "active/back-up" model, which is widely used by many organizations. This traditional model is based on an "active" operating site with a corresponding alternate site (back-up site), both for data processing and for business operations.

A split operations model, which is increasingly being used by major institutions, operates with two or more widely separated active sites for the same critical operations, providing inherent back up for each other (e.g. branches). Each site has the capacity to take up some or all of the work of another site for an extended period of time. This strategy can provide nearly immediate resumption capacity and is normally able to handle the issue of prolonged disruptions.

The split operations model may incur higher operating costs, in terms of maintaining excess capacity at each site and added operating complexity. It may also be difficult to maintain appropriately trained staff and the split operations model can pose technological issues at multiple sites.

The question of what disaster recovery model to adopt is for individual licensees' judgment based on the risk assessment of their business environment and the characteristics of their own operations.
