Server data recovery process:
A court of a server failure due to the hard disk crash the server, restore the institution in a local data data recovery operation, but data recovery is not successful, then the person in charge in Beijing to find data recovery company data recovery. The basic configuration of this server as shown in FIG. 
The server is responsible for carrying all hard drives in the server came to Beijing data recovery center, hardware engineers first of all the hard physical inspection, after testing found no physical hard drive failure, the server that is the cause of the collapse is not a hard drive failure. Server hard disk data recovery engineers a comprehensive image analysis and image files try to find out the cause server failure.
The analysis found that the server has at least two hard disks off resulting in a server crash, data recovery after exhaustive engineers removed first dropped recombinant hard disk array, the data generated in the server and the other group intact while hanging raid loaded onto the original server for verification, customer-proven, all data in the server successfully restored.
Server data recovery method commonly used:
Various types of failures inevitable in the course of servers result in data loss, so this time we need to restore the data server, the server which is usually prone to failure it:
multiple physical hard disk failure first occurs within the same array will result in data loss of; aging server module, the server system updates, power outages and other unexpected situations are likely to lead to server crashes and data loss; in the wrong plug server hard disk, accidental deletion and other human factors also contributed to another major factor server data loss .
Once the server data loss caused by faults, first of all the normal operation of the non-hot spare server failure will occur should be mirroring, there will be a physical hard disk failure protection against bump, water and the like, and if the conditions can be simple process and with the professional data recovery tool hard disk failure data can also be mirrored backup. Analysis performed on the data obtained image data to identify the structural parameters to reconstruct the original array and the logic array check server, the server can be successfully exported by the data verification.
If the server crashes due to an unknown reason, can not start problems such as data loss, avoid non-staff on the hard disk in the server to be demolished in the non-clean room, replace the head and other data recovery operations, and suggested that server administrators will keep the hard disk failure waiting for professional data recovery engineer for processing.
