【 Weak current College 】 backup important data disaster recovery five issues

Historically, lift the data security, people think of network security, how to prevent hacker attacks. For data integrity, availability, lack of attention. The so-called data security, it is with these simple to do in the enterprise, the data backup that data security is very good that the enterprise's systems are fully guaranteed. In fact, these are the simplest ideas, data backup and disaster recovery are not equal to the data, the backups are not equal to boil the ocean. Because the backup data can also be other factors lead to data corruption, such as earthquake, fire, etc., for these enterprises should enhance capacity data disaster, to further address data against potentially unsafe.
In this way, will someone asked what is the "disaster recovery"? actually simply is to minimize and avoid the disaster caused by the loss of data. Backup and recovery is the "disaster recovery" in the most important part, provide data recovery and storage capacity. Also, have the ability to improve data availability, as well as the prevention of natural disasters caused by the system stored data and loss.

Refer to disaster recovery, data backup, so think first data backup and disaster recovery are relationships? for enterprises, this relationship is reflected in what respects is the most concerned about. Business critical data loss will significantly impact business development, at the same time, causing severe economic losses. But many companies still do not understand the disaster that the simple creation of backup systems after that peace of mind, in fact, the disaster recovery system is indispensable to their mutual relations can explain the importance of disaster recovery system.

Backup is a disaster recovery Foundation

Data backup can be businesses data availability in the last line of Defense, to a system crash is able to quickly restore data. Although this is a form of disaster recovery, but with limited capacity. Because nowadays traditional backup or use of data and external tape drive for cold backup, backup mechanism also consolidated in room management, once the engine room into a disaster, data on the backup tape will also be destroyed, no effective protection for data security.

Disaster recovery non-simple data backup
Data backup or the most basic form, no data backup any disaster without practical significance. But it is not enough light back up, the real data disaster recovery is able to compensate for the lack of traditional backup, disaster recovery of the entire system can be timely. Therefore, for the purposes of disaster recovery for IT is to provide a variety of disaster prevention information system of the computer. Visible, to understand the real purpose of disaster recovery, for enterprises, how to back up data on disaster recovery and avoid the problem, you will need enterprise clear data disaster real meaning, and related tools.

For an enterprise, data backup is just the start of the entire disaster recovery, backup purpose is to be able to system failure for effective recovery. But for many enterprises, especially small and medium-sized enterprises, data backup is a simple task, for disaster recovery plan without knowing the true meaning, not the data disaster in the first place, it will result in a disaster-recovery problems.

1, the meaning is not clear to disaster recovery

Enterprise for disaster recovery is not effect assessment that spend significant effort and financial resources in the data connection, end the problem occurs when simple cover recovery, no real feeling the effects of practical significance. Even the lack of complete documentation of recovery plans and measures.

2. disaster recovery plan for feasibility

Many companies understand the significance of disaster recovery, and is not a valid plan, resulting in many disaster recovery plan is taken for granted for writing, not any lack of simulation exercises, real feasibility. Finally once the disaster, there is no adequate disaster recovery, data recovery is not effective.

3. disaster recovery configuration document not available

For large enterprises, disaster recovery and backup has a professional IT talent, not lack of relevant experience and means. However, for some businesses, especially small and medium-sized enterprises is not for the current system configuration and related files necessary for archiving. In a disaster recovery, cannot find the corresponding original system configuration document, leads to the disaster recovery unnecessary difficulties.

4. save the data document incorrectly

Many enterprise IT staff typically for a data storage medium and configuration system document simple storage, such as cabinets, shelves, ignore these data to the desired storage conditions and the required security safeguards, the direct consequences of the data document will vary depending on the moisture metamorphism, the configuration document is missing, let enterprises in data loss.

5. no more backup tools

For disaster recovery and backup, many enterprises are just some of the needs of the long-term preservation of data simple quarter annual backup, backup, especially some documentation. Due to the long, hard data document due to moisture metamorphism can not be used, but this time the enterprise has no such document is valid in more than one alternative strategies, resulting in a loss of data caused similar problems. Therefore, this class requires the long-term preservation of critical backup, you can save at least 2 different places more backup application.

It disaster recovery recovery of very critical, for effective to avoid problems, it may in the future of enterprise data security be guaranteed that the further with core data to market competition.
