Common Raid Failure Scenarios and How to Deal with them

Data Recovery

According to Platinum Data Recovery services, the majority of businesses in recent years have taken to RAID systems in order to attain enhanced security and performance. RAID which stands for redundant array of independent disks is essentially a system whereby, there is a configuration of multiple disk drives that can boost computing and storage capabilities. Such a system contains multiple hard disks that share a connection with a single logical unit to be able to offer more functions.

If there is one single operating system, RAID architecture will distribute data all over disks. The RAID architecture will have levels such as 0, 1, 5, and 6. Such a system can be composed in different manners to fulfill different purposes.

Ordinarily, there are seven different RAID levels i.e. RAID 0 to RAID 6. An example of this can be when RAID 0 is formulated to enhance computing speed. The RAID configuration divides the data evenly across all multiple desks. On the other hand, even if one disk fails then it could very well ruin the entire system, thereby culminating in a loss of data. 

All the RAID levels are very divergent with certain mechanisms for protection but the technology itself does not promise absolute data security because even they are subject to breaking down. Needless to say, the loss of data can have very adverse impacts on your work which is why it is crucial that you adopt the best possible solutions.

So in an order to avert the possibility of RAID failures, one will need to understand the common reasons which could be attributed to the failures associated with RAID damage. Enclosed in the following article, are some of the plausible reasons: 

Common attributes leading to a RAID failure 

Within the domain of the RAID data recovery systems, some of the common attributes which lead to RAID failure can be classified as application failures, software failures, hardware failures, and human error failures. Among these various categories of failures, there is the hardware failure which largely comprises of issues such as overheating, faults in the power supply, failure of the RAID controller, and hard disk component.

Then there are also software or logical issues namely, file corruption, configuration errors as well as malware attacks which are all very instrumental in the loss of data. RAID failures that are brought on by application errors typically will see the corruption of programs and applications installed in the RAID server. The most rampant of failures is that of human error which typically entails accidentally deleting files, and reformatting arrays, drives, and partitions by mistake. 

Your RAID system could encounter failure owing to the following reasons:- 

  • Failure associated with multiple disks 
  • Crashes with the server 
  • Water or fire damage 
  • Corruption because of viruses 
  • Accidental reformatting/deletion of files
  • RAID partitions that have gone missing
  • Inconsistencies in the RAID volume rebuild 

How to tackle a RAID failure?

  • Always have backups offsite 

It doesn’t matter which storage device you use, always maintain a current backup for your data. Even though RAID systems are known for their consistency and reliability, your data could very well disappear owing to many other reasons. Should there ever be a RAID failure then offsite backup on tapes, clouds and external hard drives are ideal solutions? 

  • Refrain from using a RAID system 

Raid data recovery recommends that if you notice any sign of data loss, then the next best step would be to promptly quit using the system altogether. Doing so would curtail further damage on an account of the continuous operations with the system which may worsen the problem and overwrite the data. Furthermore, installing recovery software isn’t ideal it could overwrite the existing files.
