What is raid?

The term RAID may either mean redundant array of independent disks or redundant array of inexpensive disks. In RAID data recovery the feature called redundancy is used for providing backup support to the data stored. In this a number of disk drives are fitted together as a unit to provide increased efficiency while storing data. The drives work independently, they are inexpensive and are generally arranged in an array, thus giving rise to the term RAID.

What is raid array?

Array refers to an arrangement. In RAID, the disk drives are arranged in an array so that the drives act as a unit. RAID array is convenient as well as reliable when you are looking for efficient storage options. A number of RAID arrays are available in the market like RAID 1; RAID 2; RAID 3; RAID 4; RAID 5; RAID 6; RAID 7; RAID 8; RAID 9 and RAID 10. Each array has its unique characteristics but the RAID 5 array continues to be the most widely used RAID array.

Is the raid array fail proof?

Even though RAID arrays are meant for increased efficiency in data storage, at times loss of data can take place if:

• The drives cannot be recognized,
• A new drive is replaced in a wrong way,
• More than one drives falter at the same time.

It is during these times, the need for raid data recovery comes handy.

What is raid data recovery?

RAID data recovery is the recovery process followed for data recovery, when there is a loss of data from the RAID.

It may be noted that the terms RAID data recovery and RAID recovery may mean the same. RAID data recovery is however, a more specific term, signifying the recovery of the lost data. On the other hand RAID recovery signifies the restoration and proper functioning of the RAID.

Procedure of Raid Data Recovery

The first step in the data recovery procedure involves checking of materialistic damages. In any case a damaged disk drive is found, it should be immediately replaced with a new drive. The next step involves transferring the drive volume into the RAID data recovery servers so that the arrays can be treated as image files. These arrays are then inspected further to check the root cause of the trouble.

But in the cases where the data is lost forever, several software are used that specialize in the field of RAID data recovery. These data recovery softwares help in tracing back the lost files and the folders. These data recovery softwares used in RAID recovery should be easy-to-use and should be able to trace back the lost data even if problems like – unable to recognize the drive, corrupt RAID configuration, external threats and corrupt RAID controller arise.

RAIDs can be of two types – server-based RAIDs and controller-based RAIDs. Data loss in server based-RAIDs is due to the crashing of servers. RAID data recovery in this case requires server recovery. The technician obtains back up of each hard drive before indulging in server recovery.

Ending Note

Several data recovery companies offer their expertise in the server recovery and RAID recovery procedures to help the big organizations get out of data loss trouble. Server recovery and data recovery especially in case of RAID requires years of hands-on experience. So before opting for such companies make sure their staffs possess the right kind of experience.
