RAID Server Data Recovery
RAID data recovery is a complex and sophisticated process. We take immense pride in offering our Expert RAID Data Recovery services, which aim to provide comprehensive and complete solutions for businesses and individuals across Kerala and India.
A RAID array comprises several hard drives that work together in tandem to reduce the risk of data loss. However, there are several different reasons why a RAID array may encounter issues and require recovery services. Our team of highly skilled and experienced technical engineers have the expertise to recover data from a number of complex scenarios including multiple drive failures, configuration failures, and human errors, among others. In addition to RAID data recovery, we also offer server data crash recovery and operating system recovery services for a variety of different platforms including Windows, Mac, and Linux/Unix. Our clients can rest easy knowing that they have access to a fast, efficient and reliable service to retrieve their critical data in case of any unexpected data loss event.
RAID Types And Characteristics:
- RAID 0: It’s the most basic and easy to configure RAID level. In RAID 0 technique of Data Striping is used, which means data is divided into parts equal to the number of discs in the array and one part is stored on one disc. This RAID level is preferred when the speed of processing is more important than data safety. If one of the discs fails from the array of two-disc only half of data can be saved, so know your requirements beforehand.
- RAID 1: RAID 1 uses of data mirroring technique in which one copy of data is kept on one more drive in the array. This increases latency but is great for data safety.
- RAID 3: RAID 3 uses bit-level striping of data and dedicated disc for parity.
- RAID 4: This uses byte-level stripping and uses dedicated parity disc for fault tolerance.
- RAID 5: This level of RAID strips data block wise and uses distributed parity over the array. This improves the fault tolerance but without putting an extra load of dedicated parity disc.
- RAID 6: RAID 6 is similar to RAID 5, except it adds one more parity bit ensuring extra fault tolerance.
RAID Server Failure Scenarios:
- The simultaneous failure of multiple drives.
- Accidental reconfiguration of RAID drives
- File system/operating system corruption.
- RAID Controller failure.
- RAID rebuilds failure.
- Accidental deletion of data while taking backup.
- Natural disasters like flood, fire, and earthquake.
- Failure of intermittent drive resulting in configuration corruption.
Each of RAID levels has its own characteristics,
Fault-tolerance : has the ability to endure one or several disk failures.
Performance : shows change in the read and write speed of the entire array as compared to a single disk.
The capacity of the array is determined by the amount of user data that can be written to the array. The array capacity depends on the RAID level and does not always match the sum of the sizes of the RAID member disks.
If your hard drive is clicking or making unusual noises, we strongly discourage you to turn your system on. We ask you to NOT OPEN YOUR HARD DRIVE under any circumstances. Do not make rushed decisions opening a hard drive as you will let dust from regular environment inside. It can irreversibly destroy hard drive platters, which can make it unrecoverable. Remember that modern drives are extremely fragile.
Unlike a single hard drive recovery, RAID recovery is more difficult due to parity, hard disk order, rebuilds, and drive synchronization. Therefore, we strongly discourage you to try restoring the array on your own. Any attempts (rebuild, drive swap) may significantly decrease the chances of a successful recovery outcome. Before doing anything you might later regret, call us for a free phone consultation with our specialist. We understand the urgency of the situation and can help you get your business up and running fast.
