A Disaster-Recovery IT Framework Based on Disaster Indezing Measurement Mechanism in E-Government
Recently, the frequency of natural disasters is increasing sharply, especially the seismic activities which have been reached to a new peak, such as WenChuan earthquake in China, LAquila earthquake in Italy. The disasters not only cause immeasurable casualties and infrastructures damage, but information and data losses, which will bring big troubles to the post-disaster reconstruction projects, since the re-collect work will be time-consuming and need unpredictable efforts.In this paper, a new disaster-recovery IT framework is proposed. The framework is combined with P2M (point to multi-points) and P2P (point to point) to form a hierarchical IT infrastructure distributed in different geographic location. It ensures the high availability for the data through the DIMM (Disaster Indexing Measurement Mechanism), which uses a scheduling model for the data backup and synchronization locally and remotely, based on the hierarchical infrastructure. Once the disaster happens, the framework can quickly regain the lost data in the area from its hierarchical structure, meanwhile the DIMM guarantees to maintain the data with high availability and avoid data losses.
