Design And Implementation Of An Application-level Disaster Recovery System For A Government Affairs Department In Lanzhou City

The rapid development of informatization has driven the growth of enterprises and institutions' demand for informatization.At the same time,local governments have increased investment in the construction of informatized government affairs.With the increasing reliance on big data platform business for information construction,the security and reliability of the information system itself is also facing serious challenges.The collapse of the core business system in the platform will bring inestimable consequences for normal government work.The loss of core-level data in the system will also result in irreversible losses.How to ensure data security and business continuity has become a hot topic in the field of information security.Simply relying on local backup and disk backup has been unable to meet the needs of data center development,disaster recovery backup system construction is imminent.The establishment of a disaster recovery system for large-scale data centers has fundamentally solved the impact of major disasters on important data and information,and provided useful help for data security.The impact of various disasters on the informatization system is particularly serious.The earthquake caused the collapse of the County communications system.The damage to the line was extremely serious and the local government,enterprises,and military systems immediately faltered.The shadows of major earthquakes are still imprinted in everyone's hearts.Natural disasters without warning have razed the urban areas.As a result,various types of system servers in the disaster-stricken areas are paralyzed and data are lost.This not only brings mental trauma to the local people,but also Caused huge resources and economic losses.Taking appropriate measures to resist the impact of disasters on the data security and reliability impact in the immediate moment.Based on the application of a certain unit information system in Lanzhou City,Gansu Province,this paper constructs an application-level disaster recovery system based on i2 Active for the status and needs of big data systems.In the system design and implementation,one-stop management of disaster recovery backup center server,storage,network resources.It adopts the supervision of core application servers and implements measures such as protection,backup,and storage to protect center application-level data.At the same time,real-time monitoring and management of other devices can realize the business disaster between the two data centers to achieve business level security.Through the planning and construction and performance testing of the application-level disaster recovery backup system,it is proved that it has good performance in data and information security and business sustainability.It completely eliminates potential security risks in the process of storage,use,and transmission of data.The reliability of the government system and the integration of disparate data information have also promoted the development of local government information integration.In the data transmission link,the self-developed improved intrusion detection subsystem and the multi-channel IP tunnel transmission mechanism were applied,which greatly improved the system's security and reliability.Finally,through the realization of the design scheme and the description of the advantages and disadvantages of the key technologies,the application prospects are summarized.
