| Abstract: | The most precious wealth in business enterprise is data. However the operation fault, bug of software, hardware damages, computer virus,attack of hack,nature disaster,etc. may result in data lost in computer. It is vitally important to recover the computer system as soon as possible so as to make it run normally.In this paper, the design for database disaster system was given, and the system structure, software configuration,data synchronization copy and data backup were described in detail. |
