Those using RAID storage system know how important it is to have a RAID data recovery scheme in place. This is because data loss is usually unforeseen; having reliable data recovery is therefore a wise move. RAID, also known as Redundant Array of Independent Disks, merges the use of different disk drive mechanisms. RAID data recovery is largely possible and success depends on factors such as the volume of the data lost, the extent of the damage and the recovery method used. Data loss is also retrievable in cases where the several drives fail together.
RAID 5 Data Recovery
RAID 5 data recovery is commonly used in organizations that require large storage solutions. The system needs three disks or more for performance and provides reasonable security for the data stored. The following are ways to go about a RAID data recovery:
- Close up the RAID so as to replace the drive that is defective.
- Completely shut off the server if multiple drives experience problems
- Check to see whether or not the drives are working properly
In some cases, the user will be required to replace the drive to reduce data loss. However, in some cases multiple drives experience failure at once. The best bet in such cases would be to turn off the server and seek the services of a professional hard drive data recovery expert.
Causes of Data Loss in a RAID System
Data loss can be as a result of the usual hard drive failures, experienced by all computer systems. That said; there are some factors that lead to inaccessibility of data as well as data loss.
- A Faulty RAID strip
- Damaged RAID controller
- RAID configuration damage
- Multiple hard drive failure within the array
The safest way to ensure RAID data recovery is by entrusting your server to a data recovery service provider. Even the smallest mishap when doing data recovery could end in complete loss of data within your RAID system. Upon realizing that your multiple drives are failing, the first thing you should do is stop trying to rebuild them. Do not restart your system, because this may lead to a system failure hence causing irreversible damages. It is always beneficial to you to take note of warning signs such as clicking noises. This is a major sign of an oncoming system failure and it is recommended that you stop using the computer immediately. Call a RAID data recovery service provider as soon as you begin experiencing failures within your RAID system.
