How to recover data from Server?

In fact, the information  which are located in the server storage medium are data, so that anything can cause non-subjective changes to these information are considered to be a destroy. The server data recovery  is a process to restore abnormal data on a server to normal data.

What can you do after a server failure happen?
1.    Do not have any operation on the server after a server failure. And do not to pull out  the hard disk in case this will increase the difficulty of later data recovery .
2.    Choose a professional data recovery engineer if you would like to repair it. Do not sent it to some unknown company in case there will be more restoration problems in the future.
3.    If you have pull our your hard disk, please tag their orders.
4.    If the files stored in your company’s server are highly confidential with many important data,  you’d better have your own server data recovery equipment. That is to prevent data loss or data breaches.

Do you have ever know about the server performance?
1. As a server, its reliability, that is, usability is the most important. What the server face is all the network users. As long as there are users in network, it will keep working. Generally speaking, a specialized server should work at 7*24 hours. If these large network server always have users, they will be unable to running for a long time. Therefore, the usability is the most important server performance.
2. The server provide service for a large amount of users.  If it doesn’t have a higher connection or operational performance, it cannot afford so many users. To achieve the high speed, it usually install a symmetric multi-processing and insert a large amount of high speed memory. The higher the CPU frequency, the more heat will release while working. It bring a great deal of instability to the server. On the other hand, the improvement of server computing performance is usually from the improvement of other parameters.
3. The server also needs to have a certain "scalability". As the network is always changing, the server cannot afford with the user increases if there is no certain scalability. Therefore, the server should have an expansive space and redundant components in order to maintain a high scalability.
4. The server must have a function of automatic alarm, and with a corresponding redundancy, backup, online diagnosis and recovery systems, so that the server operation can restore in time after a failure occurs. This is "manageable."

This is the performance characteristics of the server which many people may have not ever pay attention. If server data loss occurs,  how can I recover data from server? The best way is to choose a professional data recovery engineer to help you.

Server data recovery and notes in use

All information on a server storage medium are data. In abroad sense, server data recovery is a process to restore the abnormal data on server back to normal data.

What are the serve failures?

Logical faults

1.      Accident deletion, format, error partition and clone, file decryption, virus corruption.

2.      Disk data error in RAID array.

3.      RAID hard disk lost connection. A certain or several hard disk in the RAID array can not be recognized.

4.      Rebuild failure result from unexpected power outrage.

5.      The RAID array information is chaotic.

Physical failure

Server physical failure is a failure in the SAS, SCIS hard disk in server array caused by the head in hard disk and motor.

1.      The hard disk has a tap-tap noise when the computer is powered on.

2.      The hard disk doesn’t work when the computer is powered on.

3.      The hard disk cannot be recognized when the computer is powered on.

Firmware layer failure

The server firmware layer failure is the unable to recognize and the loss of some  hardware pieces in the SAS, SCIS hard disk in server array caused by the firmware damage or loss.

The solutions are as follows:

1.      Rent a server adopts RAID array to improve the fault resistance of server hard disk.

The storage of the server you rent is quite important. Hard disk is the main storage device of server with high technology content and fine machine precision. The working speed of a server hard disk has more than 10000 times a minute. It’s hard for the common SATA hard disk to reach this speed. And a small problem mat cause hard disk failure in practical use.

2.      To make a backup for your important data. You can select a network server of enterprises architecture. And use the tape drive with a professional backup software to make a regular backup.

3.      If you have deleted and lost some server files by accident, you can data recovery software to help you retrieve them. You’d better make a disk backup before that and restore data to the slave drive.

Pay attention the health information of server

The server has a drive light and it’s normally green. When the light is abnormal, you should check the hard disk. If the hard disk is damaged or failure, you should handle them carefully.

There are some other problems you need to notice after a server failure

1.      Please do not operate on server and do not put your disk out casually. That is to reduce the difficulty of future data recovery.

2.      Tag the order of hard disk if you have put them out.

3.      Write down the corresponding number of server drive interface if you need to put out the drive to recover data. Pay attention to the static electricity when you are putting them out.

The data recovery of server is very important. Once you have suffered a data loss, you should use the data recovery software to help you. If you have trouble in recovering, you can ask the Hdata recovery technical support team for help.
