【 Weak current College 】 disaster backup system effectiveness of skills

As in recent years various industry information technology development, as well as the information system of the national economy became more important position and influence, the security of information systems running enterprise decision-makers are increasingly becoming the focus of attention. In particular, domestic and international of a series of security incidents and natural disasters on the frequent reality so that people can no longer be the lifeline for enterprises themselves---data and continuously operating capacity.

Information system security threats to natural causes "maintaining" efforts under threat, and thereafter will be transmitted to the external and community, information system for calamities caused serious consequences is not apparent. Building an effective protection against various disaster threats to information systems for social harmony and stability and to avoid group event will be a success in future initiatives.

However, often backfires, when many people get started and even spent a huge cost to complete the goal of disaster prevention system construction, but there was no "crash", prepared for a disaster is not immune to which their investment loss and social impacts are difficult to estimate.

Recently, the domestic similar examples of typical, such as some enterprises in the construction of disaster recovery system, and even passed the national departments of the internal control standards "and" emergency "walkthrough, still had unexpected consequences of disasters, often a small failure can lead to long hours of business to a halt, and for emergency response system construction standards have had questions, not to talk about the launch of the disaster backup center business, that seems to be running into a lot of people, the problem?

There, we need for disaster prevention in the construction of the policy makers said, this is the effectiveness of the disaster backup construction yangbingqianri Lily 1. lack of validity of the consequences of the disaster backup system, not only difficult to guarantee it run and disaster prevention objectives, its impact to your business systems is beginning to produce side effects.

In recent years, many industry disaster recovery system planners were asked to author, how to establish a disaster recovery system? end is important disaster backup technology routes or disaster recovery processes tightly organized important? how to choose proper disaster recovery technology routes? Dr is a simple construction of building an offsite disaster backup Center?

First, the effectiveness of the disaster backup system involves the construction of the actual target of disaster prevention and in line with the objectives of the disaster recovery technology routes, secondly, the knowledge of the effectiveness of the disaster backup system must realize people a deeper reason: the disaster recovery system requirements for disaster prevention full, not only preventing small probability of natural disasters, but also to prevent the probability of equipment failure and logical failure, tight multi-faceted protection network is the only way to win. Specifically, the construction of a disaster never fail, you need to get defensive system to carry out the following links:

1) the objectives of the defensive disaster to refine

Not only General said disaster prevention, and for a variety of devices and networks are prone to accidents, and even considered missing pertinent backup system would have done this kind of defensive target, this can only continue to walk the many traditional failure of disaster prevention in the construction of the old. Early in some traditional disaster recovery system, which does indeed only disaster emergency mechanisms, but does not include the frequent failures, this defensive target itself has resulted in many of our construction financing of disaster prevention in waste, causing the reconstruction must be pushed to the disaster recovery system, or to invest in more advanced protection system.

In the information system security incidents, the more easily lead to disaster recovery system on the part of accidents often: database system crash fails to run, the data file is damaged or lost, storage device failure, etc., in our country, have multiple enterprise imparted the destructive force of such failure.

2) construction of hierarchical recovery system

In the past, people often believe that building an offsite disaster recovery center is what are offsite running or recovery. This really is a big mistake. People must know, offsite disaster backup center, its construction purposes can only be a great flood defence, enabling offsite disaster backup center, not only through rigorous business continuity audit process (for example, early warning mechanisms and declared mechanism), and you want to spend a lot of the disaster backup center personnel, data recovery to the production center is complex and lengthy process.

But part of the disaster backup technology routes also cannot guarantee that the start of the application system data consistency and integrity, which is a lot of complete construction of enterprises generally do not start the disaster backup center or fear of the disaster backup Center initiated important reasons. While various fault-prone (such as logical failure, equipment failure), if their recovery depends on the launch of the disaster backup center and repair, undoubtedly is risk amplification, airing, recovery of the fundamental effect is unpredictable. This is the failure occurred, the disaster recovery system as one of the many factors.

What fundamental solution lies in the boot advanced disaster recovery technology line, complete the level of recovery system, equipment failure (including logical failure) local repair, system startup this off-site disaster 14-character.

At present, some advanced disaster recovery technologies (flies Kang's continuous data protection disaster backup technology) have instant local repair ability so that you can in a very short period of time to complete the emergency response equipment failure (General or even to a few seconds). For a business system, business continuity assurance defuse internal failures may result in significant social risk and economic risk (for example, a large number of claims, etc.)

3) repair technology with the first validation technology

In the past, it is recognized by the repairing technique often "huicun" technology, is to backup data medium rewind production system, and then wait for the recovery of the start-up of the effectiveness and business, this kind of technology there are many risks, first during the long data before restoring, completely unexpected recovery time and recovery reliability. Second, once the recovery is successful, only to find that the recovered data is not one of your own, or requires data that does not exist, it is completely impossible to roll back to the initial state, the system will go into more serious non-Control state. In this type of technology, business continuity is not in the account, people looking to back has been in high spirits, where you can expect instant business continues to run?

At present, many industry leaders have to extend to verifying that the disaster recovery technologies, such technology characteristics is that in the event of data corruption, you can immediately provide the original format of the data point for validation, business system immediately run, ensuring business continuity in the paramount goal, after that, you can use the remaining idle sessions, further repair equipment. This system is referred to as "the first production, after repair".

4) focus on the study of transmission bandwidth

Offsite disaster recovery of an important area is the transmission bandwidth technology, this technology can lead to less often due to lack of data bandwidth delay is too large, causing the disaster backup center data is unavailable, and so on. Many disaster backup technology routes are in transmission bandwidth of streamline technologies excellently inner competition ability, this is very correct. Valid leaner bandwidth transmission technology to make the construction cost of disaster prevention in significantly reduced, or you can make the disaster backup center data real-time performance greatly improved, for data recovery from production centres will also be very effective speed boost.

From disaster recovery technologies mentioned, route choice and detail and perfection of construction object, is the disaster recovery system for construction of two chips, directly affects the final result of the construction of disaster recovery, not weeks and defects will lead directly to disaster or failure business system of the heart stops for a long time (omission), causing the crowd of more questions not already established a backup system? not already through the emergency plan of the internal audit?

This course will initially questioned those terribly embarrassed. Therefore, choose to have the advanced nature and effectiveness of the disaster recovery technology routes (such as aforesaid fly Kang continuous data protection technology, etc.), will be able to lead people to overcome the past for a disaster and the fear of failure, increase people's confidence in disaster for the people's heart scare will be gone, the information system will also be heading for safe and smooth.
