Restoring RAID Data

RAID (Redundant Array of Inexpensive Disks) is a combination of several hard disks brought togetherto construct a larger logical disk that will provide users with higher performance and overall data stability. The good thing about having RAID is that even if one or more of your hard drives become inaccessible, your system will still be able to run, albeit in a degraded performance mode. Failed hard drives that are in this raid array must quickly be replaced, to avoid multiple drive failure, which requires professional help.
If you are worried that the data inside your corrupt RAID drives are lost, do not worry, as professional raid recovery is a service that is available to help you repair your RAID and restore your data. When you send your hard drives to a good quality data recovery service, the data recovery engineer will first categorize your problem as a hardware issue or software issue. Your RAID is then connected to a computer and checked to see which drives are the ones that are causing trouble. Finally, based on the above assessments, the expert can then take proper actions to repair your hard drives. RAID recovery is a service that is available typically only from data recovery service providers that have fully equipped clean room. The clean room environment is key to working on any RAID application that has failed.

Recovering data from RAID servers can be terrible task in cases of system failures. If there is no backup, too much critical business information can be lost, and also result in the loss of a lifetime of work, storage space, and expenses. The only precaution to be taken against such a situation is to have the best raid recovery set up for the server.

In earlier times, people used large capacity servers to store their business data. But, soon, they realized that it was too expensive and started to discover new methods for data storage and recovery. Thus, raid servers were born. RAID functions as a collection of low cost hard drives working together to save data loss in times of single hard disk failure. Raid recovery can function without switching off the system and can provide full recovery of data with minimum impact on system performance. With improvements and additions to already existing technology, different versions of RAID have become very popular in consumer applications, such as RAID 0, RAID 1, RAID 0 + 1, RAID 10, and RAID 5, each with their differences in specifications and functionalities, but one similarity, i.e., easy data recovery and better server performance.

The only caveat to the variety of raid applications available is that raid 0 is frankly one of the worst ones available. Because it actually offers no redundancy, it is actually quite dangerous to your data. Avoid it if you can.

Performing RAID recovery is a very complicated process that only computer engineers or mathematicians who underwent an exhaustive training can conduct. Furthermore, every RAID recovery is unique which further adds to the complexity of the task. Hence, in the event you experienced failure in your RAID array storage, it is highly advisable to seek assistance from qualified personnel. Never attempt to perform the recovery yourself as it may potentially damage further your data thus hampering the complete recovery of your valuable files. This is especially true if you have no knowledge whatsoever on data recovery.

Here are some reasons why you should not perform the complicated task of data recovery yourself. First is that the process deals with intricate mathematical equations particularly Boolean algorithm, which only a highly trained individual knowledgeable on data recovery can perform the task. Second, manufacturers of controller and array server/NAS/SAN are constantly upgrading and releasing new array devices and parity formulas. Hence, frequent R&D is required to keep up with the recurrent changes in the system. Finally, it takes a thorough analysis of your array structure before solid and effective RAID recovery can be performed. Depending on the extent of the damage and the attempted recovery, some arrays create conditions that require sufficient time to properly diagnose for a complete recovery.

It is very crucial when seeking assistance for the recovery of your valuable data to choose a RAID recovery company that adheres to strict confidentiality protocol. Currently, where valuable information was stored in huge database, strict security measures must be implemented. You must make sure that the company you plan to hire to recover your damaged RAID array can be trusted. The company should be committed to protecting your valuable information as they work on recovering your corrupted array configuration. They should ensure that your data are well guarded from malicious hackers while in their care.

To guide you in determining a credible and trustworthy RAID recovery company, you have to inquire from them the procedure on how they go about working on recovering your data. They should restrict their operations to distant association with your data so that no file or data fragment will be stored in their system. In addition, make sure that the RAID recovery company will work on your data in a secure channel. They should make use of advanced and extensively tested encryption and authorization methods so that hackers will be discouraged from hacking your important files. Finally, ensure that your data will be handled only by their qualified personnel who underwent rigorous training in data security.

Redundant Array of Independent Disks (RAID) is a technology that encompasses grouping of multiple physical hard drives into an array that can be viewed and works as a single logical drive unit. The combined logical drive is perceived as a single drive by the operating system. This development enhances fault-tolerance and addresses performance limitations of a single disk. It offers high throughput when compared to a single hard disk. This is because parallel data transfer from multiple drives in the array yields higher transfer rates compared to non arrayed drives. The logic drive unit is capable of responding to multiple data requests in a very small interval of time. This provides a higher performance in a network environment. A variety of raid levels exist, each of which is optimized to fit specific situations.

Despite most raid set up being fault tolerant, (outside of RAID 0, which is rarely used in any sort of corporate environment and is not recommended application because of its lack of actual redundancy) damage to one of the array disks risks the efficiency and may cause corruption of the raid system. When a raid array has a multiple drive failure, IT people typically turn to professional raid recovery, as attempting to physically recovery your own raid array is an incredibly hard thing for a novice to correctly accomplish. For raid recovery to be successful, the magnitude of the damage incurred by the hard disk must be determined for the user to decide whether basic data recovery is required or whether it will require clean room repair of the entire various member hard drive. Basically, in case of severe physical damage or logical failure, only raid recovery experts should be consulted to avoid permanent loss of data. This advice, whether you are talking about a raid five or raid 10 server, will save anyone a lot of time and hassle.
