A High Availability and Disaster Recovery System

In this paper, we present the design and implementation of cluster structure and disaster recovered system that can be used in the bank, industry and enterprise. It is capable of storing great capacity data. This toolkit is targeted at data security business which want to achieve high availability and disaster recovered structure and to compare their structure with others. The comparison functions can be used to find structure differences between two performance level, especially in data safeguard. The system is developed in Unix and the great capacity data is stored in a relational database.
