Large data: Four key points to ensure the effectiveness of disaster preparedness system

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 proceed from the following four aspects:

1 The goal of disaster prevention should be refined

Can not only general said that the disaster defense, and for a variety of equipment and network of accidents but lack of pertinence, and even think backup system has completed such defensive targets, this can only say that continue to walk the traditional failure of many of the old road of disaster preparedness construction. In the construction of some traditional early disaster preparedness system, it is true that only the emergency mechanism of disaster, but not the frequent failure to include the defensive targets, which itself has caused many of our country's disaster preparedness of capital waste, resulting in the need to push to rebuild the disaster preparedness system, or repeat investment to establish a more advanced protection system. In the http://www.aliyun.com/zixun/aggregation/32730.html "> Information System's security accident, the disaster preparedness system is relatively easy to cause the failure to act the accident often is: The database system paralysis cannot run, the data file damage or loses, Storage device failure, and so on. In China, many enterprises have experienced the destructive power of such faults.

2 Construction of a hierarchical recovery system

It is often believed that the construction of a remote disaster preparedness center is a fault in the off-site operation or recovery. This is indeed a huge misunderstanding. One must know that building a remote disaster preparedness center can only protect against catastrophe. Enabling offsite disaster preparedness centers is a complex and lengthy process, not only through rigorous business continuity process audits (such as early warning mechanisms and announcement mechanisms), but also by a large number of disaster preparedness center handlers. And some of the disaster preparedness technology routes can not guarantee the start of the application system data consistency and integrity, this is a lot of construction enterprises generally do not start the disaster preparedness Center or Panic disaster Preparedness Center to start the important reason. And all kinds of easy to fault (such as logic failure, equipment failure), if its recovery depends on the disaster preparedness center of the start-up and repair, is undoubtedly the risk amplification, the dirty linen in the house, the effect of recovery is simply unpredictable. This is one of the many factors in the failure of disaster preparedness system.

What to do? The fundamental solution is to start the Advanced disaster preparedness Technology route, complete the hierarchical recovery system, is the equipment failure (including logic failure) local repair, system disaster off-site launch of the 14-word policy.

At present, some advanced disaster preparedness technology (the flying health of the continuous data protection disaster preparedness technology) with instantaneous local repair capabilities, so that the equipment can be completed in a very short time emergency response (usually even a few seconds). For business systems, the assurance of business continuity dissolves the enormous social and economic risks associated with internal failures (e.g. a large number of claims, etc.)

3) Repair technology using the first verification technology

In the past, the restoration technology was often known as the "Back" technology, which is to reverse the backup data media back to the production system, and then wait for the effect of recovery and business start-up, this technology has many risks. First, recovery time and recovery reliability are completely unpredictable before long data recovery. Second, once the recovery is successful, it finds that the recovered data is not the point of time that it needs, or that the required data does not exist, that it is completely unable to fall back to its original state and that the system will enter a more serious state of uncontrollable control. In this kind of technology, business continuity is not in the scope of consideration, people look forward to the data can come back has been elated, where can expect instant business continue to run?

At present, many industry leaders have extended their vision to the first proven disaster recovery technology, the feature of this technology is that in the case of data corruption, you can immediately provide the data in the original format of the time point for verification, business system immediately running, in ensuring business continuity of the extremely important goal, after that, you can take advantage of the rest of the idle period, Re-repair the production equipment. This system is called "first production, after repair."

4) Pay attention to the research of transmission bandwidth

One of the important areas of disaster tolerance is transmission bandwidth technology, which can often lead to data delay due to insufficient bandwidth, resulting in disaster preparedness Center data is not available and so on. Many disaster preparedness technology routes in the transmission bandwidth of the streamlining technology to practice the skills, competition ability, this is very correct. Effective streamlined bandwidth transmission technology can greatly reduce the cost of disaster preparedness, and can greatly improve the real-time data of disaster preparedness center, and can also improve the recovery of data to production center.
