Data recovery failure description:

Server model-IBM 3650 server

Raid disk array situation-there are 5 SAS 300GB disks in the server to form a RAID5 disk array

Server partition description-the storage is divided into one LUN, three partitions, the first partition holds the windows 2003 system, the second partition is used to store the SQL Server 2010 production library, and the third partition is the backup partition.

Initial test results of data recovery center:

The server data recovery engineer first made an initial check on the raid disk array and found that the physical failure of disks 0 and 4 in the server caused the RAID to crash offline.

Perform data recovery on the disk array:

1. Detach all the disks in the server from the RAID environment, connect all the disks to the secure storage of the North Asia data recovery Center, and analyze all the data in a read-only way.

two。 Based on the analysis of the combined parameters of all disks in the original RAID, it is found that disk 0 in the disk array is seriously damaged, and the offline time is relatively early, and there is no latest data, so it is not necessary to repair it. Therefore, disk 4, which is disconnected later, is an important data disk. If you want to recover data, you must repair disk 4.

3. The hardware recovery engineer of the North Asia data recovery Center cooperates with the server data recovery team to repair the hard disk (this process requires data recovery equipment).

4. After the hardware repair of the No. 4 disk in the disk array, the RAID is virtually reconstructed according to the original RAID combination parameters analyzed at the beginning. The three partitions on the original server can be identified properly and all the files can be seen.

5. Recover the important SQL SERVER database files and attach them to SQL SERVER for verification and view, the database data is normal.

Data recovery results:

After 1 working day, the success rate of data recovery is 100%.

Principles of data recovery Services:

1. Free testing

two。 Sign a confidentiality agreement with customers to keep their data strictly confidential

3. There is no charge for unsuccessful data recovery.

4. Professional data recovery engineer team service

5. Quote before data recovery, and the engineer starts data repair after customer confirmation.

6. The whole recovery process will not have any write operation to the customer's original disk to ensure that the data of the original disk is complete.
