Master emergency: What should I do if the server data is accidentally lost?

What happens when the server data is accidentally lost? Students who have lost or have not lost can look at the following six tricks, which may keep you away from the data loss.

I. Raid Disk Array

The server storage system is very important. Everyone knows that hard disk is the main equipment for server data storage. It is also a high-tech, sophisticated manufacturing device. The development of the hard disk has reached 10,000 rpm or 15,000 rpm. The ordinary SATA hard disk is also very close to this speed. During operation, a small fault may cause physical damage to the hard disk, so the general server uses Raid disk array storage. Strengthen the fault tolerance of the server hard disk.

Second, regular backup

In addition to the Raid hard drive fault tolerance, for some very important data to use other equipment to back up from time to time, recommend enterprise users, business users architecture network server, select tape drive With professional backup software (VeritasNetbackup, CAArcserver), regular backups are made on a regular basis. If it is an individual user, it is recommended to use an economical CD-ROM/DVD disc as a backup method.

Third, download recovery software

For some simple accidental deletion or formatting, for a small number of files, personal technology is good, you can download some recovery software online (DataRecove, Easyfurce Etc.) Try to recover. Of course, you can use Ghost software to make a full backup of the disk before you do it. At the same time, it is best to pick up the disk when recovering. Of course, if the results of your personal recovery are not satisfactory, please seek professional data recovery company to operate.

Fourth, do not blindly operate

If you find that the server data is lost, Qiancheng should not blindly operate, reducing the probability of data recovery. You can find regular data recovery company technical support by phone, listen to proprietary advice or ask a professional technician to check. At this point, you can shut down and stop the hard disk to read and write data. No more data is written to the partition or hard disk where the data is lost. Reduce secondary damage.

V. Observe the hard disk indicator

Always pay attention to the running status of the server hard disk, and observe the indicator of the server hard disk. Generally speaking, the appearance of the server has every hard disk indicator. Normally it will be green. When the indicator shows a special situation, you need to take relevant measures to check whether the hard disk device is normal. Once the hard drive is damaged or the data is lost, don't be alarmed, be sure to keep your head cool. The following are the recommended measures for common hard disk failures and users:

1. Hard disk damage or data loss:

1) The hard disk has a strange sound, and the head is not looking for it properly. Address, in order to prevent injury to the disc body, you need to immediately power off the non-removable hard drive, you need to pay the professional company to open the inspection of the ultra-clean room;

2) BIOS does not recognize the disk, can not find the hard disk, first Please check with your computer engineer carefully. You must first inform us of important data and be careful. In order to avoid being damaged again, the hard disk is damaged.

2, the hard disk is normal but suddenly can't read the data:

1) Do not perform the operation of rebuilding the partition table or formatting, etc., which will destroy the data. Although there is still a rescue, it is impossible to save 100%. Back to all the data, in case the damage is an important document, it will not be worth the loss;

2) First judge correctly, do not reinstall the Windows operating system or use the recovery disk, it is easy to cover the data area, and usually The coverage area is a few hundred M calculations;

3) If the Scandisk and Vrepair are automatically executed during booting, please press Esc or the space bar to cancel the action, first check the cause of the damage, so as to avoid the internal file being damaged.

Six, profiteer identification

Of course, if you confirm that the server data hard disk has a special fault, you need to open the process! At this time, it is very important to choose a professional data recovery company. At present, data recovery is low due to the high technical threshold, compared with the average computer maintenance company, but it does not mean that it does not. Some technical strengths are poor, the environment is limited, and even some JS that can only be transferred to other companies for operation can be seen everywhere! At this time, please recognize it carefully. Avoid being deceived and causing late losses that cannot be estimated.
