| Abstract: | Enterprise information system is an infrastructure platform of modem enterprise operation. Data is critical resource that is related to the interest of client and enterprise. Business continuity and data availability are important problems in relation to enterprise survival. Disaster tolerance system can ensure that enterprise business operate continually and minmize the loss when disasters occur. Some technologies can be used for disaster tolerance system. The solutions can be based on the levels ofapplication, DBMS, intelligent storage copping and mirroring software. Enterprises must evaluate their risks and select the appropriate solutions to implement the business continuity and data availability. |
