O & M tips: preventing data loss"

Server data storage security is an important part of ensuring the normal operation of servers, and is also the core of enterprise network information construction. The management staff of each company attaches great importance to the important data stored on the server, including: confidential Office documents generated during various management processes, customer data accumulated during business operations, important documents involved in R & D, etc. Users always pay attention to the running status of server data storage devices. As a member of the storage device, the hard disk plays an important role. However, among all hardware components, the hard disk is a product with a relatively high failure rate. The hard disk has a high price but data is priceless. The warranty regulations provided by major hard disk manufacturers are only applicable to hard disk components, the data in the storage is not guaranteed.

So, how can we correctly handle server data storage and prevent data loss? Bkjia.com introduces six methods to prevent data loss. We can refer to them as the "Six-pulse sword" to prevent data loss"

The secret to data loss

The server storage system is very important. The first important thing is the data carrier, that is, disks and tapes. Among the six-pulse swords, the sword and the road are fierce, and the storm is like a storm. Therefore, bkjia.com compares Fault Tolerance of Raid hard disks to that of the six-pulse sword to prevent data loss. As we all know, hard disks, as the main device for server data storage, are also highly technical and sophisticated equipment. The development of server hard disks has reached 10000 or 15000 rpm per second, ordinary SATA hard disks are very close to this speed. during operation, a small fault may cause physical damage to the hard disk. Therefore, servers generally use Raid disk array storage, enhance the fault tolerance function of server hard disks.

Prevents data loss

In addition to Raid hard disk fault tolerance, we recommend that you use other devices to back up important data from time to time, choose a tape drive with professional backup software (veritassp_and CAArcserver) to regularly and regularly complete backup solutions. If you are an individual user, we recommend that you use the economical CD-ROM/DVD disc as a backup mode. It can be said that re-backup of important data is a stupid method, but such a stupid method is indeed extremely effective. In the six-pulse sword, Guan Chong's sword features a simple victory, so bkjia.com compares important data back up to prevent data loss.

Prevent data loss

You can download some restoration software (such as DataRecove and Easyrecove) on the Internet to restore some simple accidental deletion or formatting files, before doing this, you can use the Ghost software to make a full backup of the disk, and at the same time, it is best to connect the disk to the slave disk during restoration. Of course, if you are not satisfied with your individual recovery results, please seek a professional data recovery company to perform the operation. However, there are many restoration software and related data companies. You can choose a software or company based on your own characteristics. The characteristics of Shang yangjian in the Six-pulse shenjian are clever and flexible, unpredictable, so bkjia.com compared data recovery tools with the company to a powerful Shang yangjian that prevents data loss.

Prevents data loss

If server data is lost, do not perform operations blindly to reduce the probability of data recovery. You should quickly seek technical support from regular data recovery companies by phone, listen to private suggestions, or ask professional technical personnel for inspection. In this case, you immediately shut down and stop reading and writing data from the hard disk. Data is no longer written to the partition or hard disk where data is lost. Reduce Secondary damages. Further expansion of data loss prevention should be carried out immediately upon discovery. This work should be "fast. Bkjia.com compares this measure to a rare sword that prevents data loss, because it is characterized by light and rapid development.

The secret to data loss

Finally, Shao zejian is ready. Hey hey, this is also the favorite one of bkjia.com's editors, when Comrade Xiao used a set of "Shaoze sword cultivation methods" in the village, he almost killed JIU mozhi. Now I think it is interesting. Shao zejian, the secret to prevent data loss, is always paying attention to the running status of the server hard disk. It is a task that requires frequent attention to the hard disk, the characteristics of Shao zejian are that the work is no longer appropriate.

Generally, each Hard Disk indicator is displayed on the server. Normally, the indicator is green. In special cases, you need to take relevant measures to check whether the hard disk device is normal. Once the hard disk is damaged or data is lost, do not lie. Be sure to stay calm. The following are the common hard disk faults of computers and recommended measures for users:

1. Hard Disk damage or data loss:

1) When an abnormal sound occurs on the hard disk, the head is not properly addressable. To prevent injury to the disk body, you need to immediately remove the power from the hard disk. You need to submit a professional company with a clean room to open the disk;

2) If the BIOS does not recognize the disk and the hard disk cannot be found, ask the computer engineer to check the disk carefully. You must first inform the System of the important data and handle the data carefully. To avoid hard disk damage caused by misoperation again.

2. the hard disk is normal but suddenly the data cannot be read:

1) do not re-create a partition table or format it to destroy the data. Although there is still a rescue, it is no longer possible to save 100% of all data. In case of damage, the loss of important files will not be worth the candle;

2) first, make sure that you do not reinstall the Windows operating system or use a recovery disk to perform operations. It is easy to overwrite the data area, and the coverage area is usually calculated by several hundred MB;

3) If Scandisk and Vrepair are automatically executed during the boot, Press Esc or space key to cancel the operation and check the cause of the damage to avoid a large amount of damage to the internal file.

Frequent monitoring of server hard disks is very important

Prevents data loss

Of course, if you confirm that the server data hard disk has a special fault, you need to open the disk! At this time, it is very important to select a professional data recovery company. At present, because of the high technical threshold, data recovery is less than general computer maintenance companies, but less does not mean no. Some JS codes with poor technical strength, limited environment, and even some that just take the order and then switch to other companies can be seen everywhere! At this time, please carefully identify. Avoid being cheated, resulting in incalculable post-loss. Selecting a related repair company is a task of dealing with people. If you accidentally arrive at a profiteer, you must take the momentum to safeguard your legitimate rights and interests. In the six-pulse swordsmanship, zhongchong is characterized by a huge opening and imposing momentum. bkjia.com advocates that you also need to come up with the momentum of zhongchong to deal with related computer maintenance companies, strive for the best service quality.

Now, bkjia.com is the edited "Six-pulse sword" to prevent data loss. We hope this will help you in your daily work.
