What is the process of RAID Recovery for your data?

RAID stands for Redundant Array of Independent Discs. Originally though, the “I” stood for Inexpensive. This is a method of data storage where you have more than one storage disc and the same data is saved on the different independent discs. This is done to protect the data in case of drive failure, it will ensure continuity of access to the data even if one of the disks may have been corrupted or destroyed.

Raid recovery

This is the process of recovering the data from the different independent discs that may have failed for one reason or another. Some of the common problems are controller problems, hard drive failure or disk corruption.

With RAID recovery, you need to reconstruct the parameters and follow through to recover the data on the discs. You may need to use certain tools for example, ZAR RAID recovery is one of the highly recommended tools that can determine the parameters and recover the data.

How it works

RAID recovery places the data on multiple discs and then balances the input and output operations even though they are overlapping. This will improve the performance of the system data management. By storing data on multiple independent disks, the ability for the system to tolerate faults is improved since any of the independent disks can take over if one is affected.

With RAID storage, the system does not see the disks independently, this is all one logical hard disk. RAID functions on what is referred to as disk mirroring or stripping. This partitions the storage space into units that can range from 512 bytes to several megabytes. The petitions are well organised into small strips so that the system is able to read the different disks at once especially in the case of large data storage.

Sometimes people may confuse RAID as a backup system so it is important to stress that RAID will mainly help you when there is a system failure with a disk, the other disk will cover up as you replace the faulty one, but when it comes to corrupted data, you need to understand that if corrupted data is stored on your server, it is mirrored to all the multiple disks so you still need to have a backup software even when you are using RAID.

In Summary, RAID will help you speed up your server and provide tolerance in case of a system failure with one or more disks as it provides an alternative access to the data as the other disks are attended to.
