Correctly face server data storage to prevent data loss

Server data storage security is an important link to ensure the normal operation of the server, and it is also the core of enterprise network information construction.

The management personnel of every enterprise attach great importance to the important data stored in the server, including: confidential office documents generated in various management, customer information accumulated in operations, important documents involved in research and development, etc. Users always Pay attention to the operation of the server data storage device. As a member of storage devices, hard drives play an extremely important role. However, among all hardware components, hard drives have a relatively high failure rate. Hard drives are valuable, but data is priceless. The warranty regulations provided by major hard drive manufacturers only cover the hard drive components themselves, but do not provide coverage for the data stored in them. Related guarantees.

So, how to deal with server data storage correctly and prevent data loss caused by accidents and disasters?

1. Server storage system is very important. As we all know, hard disk is the main equipment for server data storage. It is also a high-tech and precision-made equipment. The development of server hard disk has now reached 10,000 rpm or 15,000 rpm. Ordinary The SATA hard disk is also very close to this speed. During operation, a small fault may cause physical damage to the hard disk. Therefore, generally servers use Raid disk array storage to enhance the fault tolerance function of the server hard disk.

2. In addition to Raid hard disk fault tolerance, some very important data must be backed up from time to time using other devices. It is recommended that enterprise users and business user-structured network servers use tape drives in conjunction with professional backup software (Veritas Netbackup, CAArcserver), and perform relative backups regularly. Complete backup solution. If you are an individual user, it is recommended to use economical CD-ROM/DVD discs as a backup method.

3. For some simple accidental deletions or formatting, if there are not many files and your personal skills are good, you can download some recovery software (DataRecove, Easyrecove, etc.) from the Internet to try to recover. Of course, you can use it before doing so. Ghost software makes a full disk backup, and it is best to connect the slave disk during recovery. Of course, if you are not satisfied with the results of your personal recovery, you need to seek help from a professional data recovery company.

4. If you find that server data is lost, Qiancheng should not operate blindly to reduce the chance of data recovery. You can find formal data recovery company technical support by phone, listen to proprietary suggestions or ask professional technicians to check. At this point, you can shut down the computer to stop reading and writing data from the hard disk. No more writing data to the lost partition or hard drive. Reduce secondary damage.

5. Always pay attention to the operating status of the server hard disk and observe the indicator lights of the server hard disk. Generally speaking, the appearance of the server has an indicator light for each hard disk, which is usually green under normal circumstances. When there is a special situation with the indicator light, relevant measures need to be taken to carefully check whether the hard disk device is normal. Once the hard drive is damaged or data is lost, please do not lie and be sure to keep a cool head. The following are common computer hard drive failures and suggested measures taken by users:

1. Hard drive is damaged or data is lost:

1) There is an abnormal sound in the hard disk. At this time, the magnetic head is not addressing normally. In order to prevent damage to the disk body, the power must be cut off immediately and the hard disk must not be disassembled. It must be disassembled and inspected by a professional company with a clean room;

2) The BIOS does not recognize the disk and cannot find the hard disk. Please ask a computer engineer to check it carefully first. You need to be informed that there is important data in it and it needs to be handled with care. To prevent the hard disk from being damaged due to misoperation again.

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

1) Do not perform actions that will destroy the data, such as rebuilding the partition table or formatting. Although there is still hope, it is impossible to 100% recover all the data. If important files are damaged, the gain outweighs the loss;

2) Make the correct judgment first. Do not arbitrarily reinstall the Windows operating system or use a recovery disk to operate. It is easy to overwrite the data area, and the coverage area is usually several hundred MB;

3) If Scandisk or Vrepair is automatically executed during boot, please press Esc or the space bar to cancel the action and check the cause of the damage first to avoid massive damage to internal files.

6. Of course, if it is confirmed that there is a special failure in the server data hard disk, it needs to be opened! At this time, it becomes very important to choose a professional data recovery company. At present, due to the high technical threshold, there are fewer data recovery companies than ordinary computer repair companies, but less does not mean that there is none. Some JSs with poor technical strength, limited environment, and even some that just take orders and then transfer them to other companies can be seen everywhere! At this time, please identify them carefully. Avoid being deceived and causing incalculable later losses.
