Database Disaster Recovery

Content Summary: The data disaster tolerance problem is the government, the enterprise and so on in the informationization construction process to be confronted with the important theory and the practical significance research topic. In order to realize the disaster tolerance, it is necessary to design and research the disaster-tolerant related technology, the requirement analysis of business system, the overall scheme design and system realization of disaster tolerance. 　　Based on the current situation of Xinjiang National Tax Service and the target of future disaster tolerance construction, this paper expounds the concept and technical essentials of disaster tolerance, focuses on the analysis of the business data processing of Xinjiang national tax, puts forward the concrete disaster-tolerant solution, and gives the test example. Key words: ...

Until now, those who started out with cloud computing have proven the viability and management of cloud computing deployments and the benefits of cost savings, and more and more organizations are now adopting it as their core business application and IT services. In fact, with the success of cloud computing driven by software-as-a-service applications like CRM and ERP, more and more organizations are now hoping to replace traditional live backup with cloud-based disaster recovery (DR) solutions. Gartner pointed out that until 2014, more than 30% of medium-sized enterprises ...

Following a series of business-focused technologies, including CRM, ERP, and collaboration, cloud computing has pushed its sphere of influence into disaster recovery scenarios. This is certainly good news for end users. A sharp fall in prices has also made it easier for small businesses, which have not dared to do so in the past, to prepare for a disaster recovery mechanism, as well as to bring richer options to business users. However, cloud is by no means omnipotent, and for many enterprises, the cloud base disaster recovery is not enough or even completely deviated from the demand track. In order to help you work out a set of goals with the enterprise ...

Early-adopters have demonstrated the viability of cloud computing and the benefits of managing and reducing costs, and businesses are increasingly moving their core business applications and IT services to the cloud. In fact, after verifying the viability of SaaS applications, such as CRM and ERP, in the cloud environment, many organizations are considering using cloud based disaster recovery (DR) to replace their traditional onsite backup and disaster recovery. By 2014, Gartner says, more than 30% of midsize enterprises will be using cloud disaster recovery or recovery as a service. This leads to a problem: your business to do ...

Cloud storage concept is extended and developed in the cloud computing, through the cluster application, network technology or Distributed file system functions, the network of a large number of different types of storage devices through the application software together to work together to provide data storage and business access functions of a system. When the core of cloud computing system operation and processing is large amount of data storage and management, cloud computing system needs to configure a large number of storage devices, then cloud computing system is transformed into a cloud storage system, so cloud storage is a data storage and management as the core cloud computing system. Cloud storage ...

Traditionally, a business needs to develop a disaster recovery plan based on their respective recovery-time objectives (RTO), enabling them to recover operations within a certain amount of time. Typically, this may involve rebuilding infrastructure and applications over a period of more than 72 hours, and handling the purchase and deployment of tangible assets. In reality, this process may take a longer time. Downtime for critical applications is by no means an option, and people always recommend a full redundancy, http://www.aliyun.com/zixun/aggregat ...

The effectiveness of disaster preparedness system relates to the actual target of disaster preparedness construction and the technical route of disaster preparedness, and it is clear to understand the effectiveness of disaster preparedness system people must understand a deeper truth: the disaster preparedness system construction requires disaster defense all-round, not only against the small probability of natural disasters, More to prevent the probability of large equipment failures and logic failures, strict multi-directional protection network is the way to win. To build a disaster-prevention system that never fails, we need to get down from the following four aspects: 1 The goal of disaster prevention should be refined not only generally speaking of disaster defense, but for ...

First, the preamble: When the database server is established, we must first do is not to consider in this support for the database server running which are carried by the MySQL program, but when the database is destroyed, how to safely restore to the last normal State, making the loss of data to a minimum. Or just the establishment of the database server, only to show what it can do, does not mean that it can be stable to do something. The efficiency and comprehensiveness of disaster recovery is also a quasi-factor of system stability, especially for a server system. This section introduces the automatic database backup to ...

No database system can avoid a crash situation, even if you use a clustered, two-machine hot standby ... It is still not possible to completely eradicate the single point of failure in the system, and for most users, this expensive hardware investment cannot be sustained. So, when the system crashes, how to restore the original valuable data becomes an extremely important problem. In the recovery, the ideal situation is that your data files and log files are intact, so only need to sp_attach_db, the data file attached to the new database, or in the downtime ...

Introduction: The Rise of server virtualization and cloud computing technology does not mean that we no longer need good it disaster planning, toigo that new technologies and budget cuts should not be a reason for IT managers to reduce their concern for disaster tolerance, and that disaster preparedness must receive priority attention. The rise of server virtualization and cloud computing technology does not mean that we no longer need good it disaster planning and the tape technologies that might be used in these plans. Here are some of the disaster-recovery techniques that Jon Toigo mentioned in his keynote address at his storage decisions meeting. Act as a part of
