| Classical explanation about disaster recovery of data center system in banking is thatdisaster recovery is not a technique but engineering.Disaster recovery of data center system for banking has being established abroad forlong time. When being established disaster recovery of data center system for banking, it isnecessary to consider not only influence extent of destructive disaster, but also allrequirements of disaster recovery of data center system for banking. The all requirementsinclude how to deal with the disaster; cost for practicing disaster recovery; techniquepracticability against disaster; complying with the local rules and laws; meeting requirementsof audit. Meanwhile it must consider the relation with both governments and business servers.There are many established models of disaster recovery of data center system for banking now,which are relatively perfect.Many domestic commercial banks have begun to promote establishing disasterrecovery systems on the basis of the plan now. Although it is getting obvious day by day thattendency establishing information systems of domestic commercial banks is centralization.Both main data of nuclear business information system and logic treatment are centralized togeneral center, and all operations are carried on in the general center. In the future period ofconsiderable length, essential position about business information system of the bank’s branchwill not change very much. The business information system of bank’s branch mentionedabove is noted for precedence treatment, sink information of network, special businesstreatment based on IT architecture of whole bank. Rapidly developing of24hour networkbank, mobile phone bank and micro message bank, which are used in millions’ families, isbound to follow the rapid advance in large scale global network. Banking business hourscannot be limited from9a.m. to5p.m. It is fact to provide customers continuous bankingservice24hours per day,7days per week for all year long.Compared with risks of data concentration in the general central computer room, thereare several risks in the computer rooms of branches of commercial bank similarly.Providing directly service for bank customer, a front branch office of bank has higher riskprobability which follows service time is prolonged to24hours per day,7day per week forall year long. If disasters suddenly happen, for example power failure, fire disaster, flood and earthquake, a lot of banking business in the bank branch service area will be at a standstill,which has great influence on the normal movements of funds of both the public customersand the private customers.In order to effectively reduce disaster risk of information system in the service area ofcommercial bank branch, immediately recover from disaster, safeguard customers’ benefitsand satisfy supervisory requirements, the studying task takes a practicing plan of establishingdisaster recovery system of a commercial bank as a case. The practicing plan is carefullystudied, designed and made in detail again. Key points studied focus on five differentestablishing plans of bank disaster recovery systems after great concentration of informationsystem of general bank level in domestic commercial bank. Then both advantages anddisadvantages of the five plans are analyzed to put forward an available, technical programmeabout establishing general reliable disaster recovery system for branch of commercial bank. |
