Such interruptions may happen because of power failure, but that can be avoided by purchasing the system that will provide you with interruptible power supply. If you can prevent it to happen, why not managing it? You can provide the power supple for the complete RAID system, or use the battery that will save the content in case of power failure. The RAID 5 write hole happens, but the risk of occurring that can be reduced, so make sure you have done all you can to avoid it since you can’t afford yourself to waste your time on fixing problems and worrying about the problem.
Causes Of Data Loss On RAID 5 System
The Redundant Array of Independent Disks probably does not may not mean you anything. But the abbreviation RAID sounds more familiar to you, does not it? The RAID technology is used by professionals who need quick access to their files and who want to work safely. But no matter how we try, disturbances may happen on the best systems, so RAID 5 problems can happen as well. Data corruption may occur but you can fix the problem no matter what caused it. Usually, all the hard disk models which are part of RAID system can be recovered in a similar way.
The causes of data loss are many. One of the rarest is power failure, but it can be prevented by simple techniques that will provide continuous power supply. The data can be erased by accident, but anyone who has done that may be sure that the data can be recovered. Of course, being careful is important, but things like that unfortunately happen. The other cause for losing data is system failure caused by viruses or similar. Fixing RAID 5 problems is usually the same for all the causes. The usual procedure uses cloning the disks which are working in RAID system.
