How to improve the RAID5 data recovery success rate method

For IT administrators, a RAID data disaster is always the most headache, because the relevant recovery technology involves a wide range of knowledge, ordinary administrators and even the server vendor engineers can not solve. Since a RAID data disaster should not be handled by an administrator, what should administrators do at this point?

Do not force online: dangerous Methods of operation

In the event of a failure of one of the server's hard drives, the general server will have a offline indicator prompt, which requires the user to replace a good and identical hard drive, and re-check the algorithm. This is supposed to be a very normal operation, but it is not surprisingly that many raid disasters are caused by this.

As an example of a RAID5 disk array with a larger number of hard disks, it is likely that several hard drives purchased at the same time have been unstable. And the server's offline hint may not be the most accurate, often false alarm (also have the factor of the hard disk stability) or missing other also have the hidden trouble of hard disk. In the seemingly normal forced-on-line process, the hard disk needs to do a lot of read and write operations, at this time is a severe test: good luck and natural smooth, and bad luck will lead to other hard disk suddenly dropped, at this time make the problem more difficult.

Of course, a hard drive drop-off prompt, or a drop-off hint within the raid fault tolerance range, forces the line up or must be performed. However, before this step, we strongly recommend that you check the stability of each hard drive, so that more insurance. Do not overlook such a small detail, often this step can keep the raid server from paralysis.

Protect the first scene: do nothing to be safest

For the manufacturer, all warranty commitment is limited to the hardware equipment, that is, the failure of the disk array caused by the data crisis is irrelevant, responsible for the user replacement or repair has been considered "dedication". But what users need is not to retrieve the hard drive or rebuild the raid, but more valuable data. If the search machine manufacturers, this is tantamount to "asking for trouble", because the so-called after-sales service is not from the user's original demand, as soon as possible to ensure that hardware equipment intact instead of sacrificing data. Of course, a well-known brand of server vendors or agents will proactively choose to "pay" for the RAID data recovery service fees for big customers, but this is only a separate case.

The head engineer of the day Shield Data Recovery Center was introduced, as the case of the service engineers of the search service was repaired and the final data was completely destroyed almost every week. After all, after-sales service engineers are basically biased towards hardware, and RAID data recovery is mainly software-based operations.

In addition, even simple test operations may cause later data recovery inconvenience. In the case of normal RAID5 recovery, when the hard disk is damaged beyond fault tolerance, the image of the damaged hard disk must be fully extracted for final recovery. And if frequently on the hard disk power, it is easy to cause the head further fatigue damage, and even scratched the disc. The right approach should be to immediately consult a professional data recovery service provider.

Choose Professional data Recovery provider: Don't Lose your way

According to the day Shield Data Recovery Center statistics, many data recovery failure cases are because the user has sought the wrong solution. Server users rely on the after-sales service is often not professional, RAID disk array problems after the easy choice of reconstruction, data loss is even worse. When choosing a data recovery service provider, judging by size and industry reputation is a practical shortcut. In this regard, the service network throughout the country's Day Shield data Recovery Center has a deep accumulation, can help the vast number of users who encounter a RAID data disaster in time to tide over the difficulties.
