Backup Host Plan for Banking Information System Based on Capacity on Demand Model
The financial information’s operation of banking cannot allow the services to discontinue and lose data. To reduce the banking service impact because of unexpected disasters, this study plans to use the composite remote backup model and proposes to use the CoD (capacity on demand) model to design the backup center’s host to protect the information system that is suitable to the recovery requirement for banking. This study uses the analysis of variance method to census and analyze the fault factors of some banks’ information system and derives the equation of estimation to calculate how much redundancy capacity to purchase for the remote host. This should reduce the setup cost substantially than is possible using the traditional model.
