近來歷經911恐怖攻擊、四川大地震等一連串超過區域性的重大災難，造成許多企業因重要資料或系統毀損，無法繼續營運。企業漸漸體認到異地備援的重要性，紛紛進行異地備援建置。隨著双中心架構興起，異地備援已脫離單純備份企業系統資料，正式納入企業資訊系統，分擔企業日常作業負擔，在企業營運上扮演更重要角色。 企業建置異地備援需投入極大資源，為避免重覆投資，在各方面均必須作審慎評估，尤其是異地備援機房選擇更是重要。因為備援機房一旦建置後，如因特定因素必須更換地點時，所需花費之金錢及其他資源，將數倍於先前建置時的規模，所以企業在異地備援機房選擇皆以十分慎重之態度來面對這個決策議題。 企業在進行建置異地備援機房決策時，須先決定是自建機房或委外專業機房（如資料中心，Internet Data Center，IDC）建置。本研究以台灣地區金融業個案公司為研究對象，利用文獻整理分析、實地觀察與專家訪談，探討企業於決定異地備援機房地點時考慮的關鍵因素，研究結果可供未來企業於建置異地備援時，選擇備援機房的參考。 We’ve undergone a string of global catastrophes in recent years such as the September 11 Terrorist Attack and the Big Earthquake in Sichuan; the impacts of these global disasters have interrupted the daily operations for many corporate enterprises due to the loss of crucial data or large-scale system damage. Corporate enterprises have now slowly but surely realized the importance of remote backup mechanisms and have started to construct them. As the development of the Dual Data Center started to rise, the remote backup is no longer just for backing up a company’s system data; instead, it’s being integrated into the enterprise information system and is now sharing the daily operation loadings and playing a more important role in the daily functions of the company. To build a remote backup control room, enterprises have to invest a tremendous amount of money and resources. Therefore, spending money more effectively and wisely in any IT projects is very important. To avoid investing money repeatedly and wastefully when implementing the IT projects such as building a remote backup location, we should painstakingly examine every aspect of the project, especially when choosing the location of the remote backup control center. Once the location of the control room is chosen and constructed, moving it to another location later on will be very costly and difficult to do. The money and other resources needed to move the control room to another location later on will be several times more. Therefore, most companies discuss this issue very thoroughly and circumspectly when choosing the location for their remote backup control room. When making plans for the remote backup control room, we need to decide whether we want to build it by ourselves or choose to use services from a dedicated server management center such as the IDC (i.e. Internet Data Center). This research studies the key considering factors the enterprise companies have when deciding the location of the remote backup control room. We studied several companies in the Finance and Banking industry in Taiwan and we documented and analyzed these individual cases. We went to visit their remote backup site and conducted interviews with their IT experts and managers on site. We hope that the findings of this research paper would be a good reference tool for the IT professionals in the enterprise when they are trying to decide the location of their companies’ remote backup control room.
