Types Of Network Attached Storage Devices

The usage of network attached storage devices is common in big companies that employ a lot of users who need to share information among themselves quickly and practically. This device is helping all the workers who work in a team to share files, images and text documents in a way that improves the working experience. Indeed, sometimes it happens that the data is lost if something happens to device, so nas recovery will be necessary. To prevent losing data, each worker should know how to work on device properly and be responsible.

There are few types of network attached storage devices available. There are simple NAS devices that consist one or two disks. Devices that are more sophisticated are used in big corporations or offices and can consist more than 60 disks. The number of disks depends on needs each company has and on size of data that needs to be stored on one place. Of course, having more disks decreases the chances of complete data lost because of some data is saved on more disks, the nas recovery may be faster and more successful. Each employer should know what to do if the data is lost and how to use the software for recovery. read more

Tips On Avoiding The RAID 5 Write Hole

Be providing the write atomicity you can avoid the RAID 5 write hole to occur. The atomicity refers to operations that cannot be disturbed in a moment when the process is running on. The word atomic in this context means that the operation that is being performed should be completed to its end, or not performed at all. In a case that it is being interrupted, the write atomicity will save the system in a state where it was at the moment when the interruption occurs, or will even manage to complete the operation to its end.

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.

Viruses And Power Failure Causing Data Loss

Viruses can affect our computer programs in a way we definitely do not want them to. For instance, they can make severe damage on our RAID 5 system, so that we lose all the data from it. Is it possible to recover RAID data if viruses take away our documents or if they modify them? In most of the cases, the files and folders can be returned but the professional hand has to take charge. If a user who experienced data loss caused by virus does not know what to do to help the system to be recovered, it is recommended to do nothing.

Simply call the professional who will take effort to recover RAID data. Sometimes the cause is not a virus but losing the power. If that happened to you while you were working in a system, wait until the power returns and then turn the system on. If the RAID 5 will not be up after this, you will need to call for help. In addition, if the system turns on but you notice that data are missing, you need to call for well-experienced technician as soon as possible to recover the data from your RAID 5 system.

Better Prevent The RAID 5 Write Hole Than Fix It

Disk cloning is one of the common ways of fixing data loss from the RAID system disks. After all the damaged or infected disks are being cloned, the next step is simulating the RAID field, which is being performed in a same way as normal RAID functioning. One of the known errors on RAID is RAID 5 write hole and if it happens, the user who works on this advanced technology system should ask for help. The repairman should do the cloning and simulating mentioned before.

The complexity of simulation will depend on complexity of the RAID field itself, as well as on condition of clone disks. The process of simulation that is being performed to imitate the work of RAID implies finding the parameters of RAID fields, the disk order and all the other details. While using the RAID system, a user should know some tips in order to prevent RAID 5 write hole. First of all, if the disks are producing strange mechanical noises, it is best to turn it off and call the help immediately. Any unprofessional activity performed on damage disks can worsen the situation, so it is best to sit and wait if anything else is possible.

Back Up Prevents Data Loss In Case Of RAID 5 Problem

Big corporations who have the need for advanced technology to be used in work often use RAID systems. One of the models of this technology is RAID 5. It enables the workers to exchange the data and also store the data on the system. It contains three or more disks that allow storing a lot of information. The access to that information is very fast, which is important for companies who live by the motto: Time is money. So, when RAID 5 problems occur, it is necessary that the failure is removed as soon as possible. It is always good to have the employee who will take care for the “health” or the condition of the RAID system.

Also, users may also take care for the system and contribute with their attention. A regular back up is one of the most important things if users want to improve the data safety. Sometimes the disks need to be cleaned, but before that, the back up is a must. Also, if you know that the computer technician will install a new software on the system, it is good to do the back-up before installing as well. In a case, something goes wrong, you will save the data by doing the back up.
