Redundant Array of Independent Disks or RAID offers you several advantages over other storage arrangements. No wonder it is widely used by individuals and businesses all over the world. In addition to providing fault tolerance, RAID also helps in improving the data transmission rate. Companies that value the security of their data choose RAID over other such data storage systems. RAID sets are also exposed to the usual problems of data loss.
So when it comes to data disasters in disk array environments, RAID’s contribution to emergencies occurring due to data loss is significant. There can be a variety of reasons for RAID data loss. Instead of focusing on the negatives, you should look for the different ways to help you perform RAID data recovery in Melbourne, Perth and other locations in Australia. Though it is essential to know the reason behind the data loss for finding the right solution, the primary focus should always be RAID data recovery. Before moving further, let us first discuss a few important related topics.
Why is RAID so famous?
Many people are aware that RAID is so famous, but only a few of them know the reasons for this popularity and preference. As already mentioned, it offers several benefits that put it above other storage systems. In addition to higher availability and improved storage performance, there are other benefits as well. Let us talk about a few of those:
Fault tolerance: This is amongst the essential benefits of using RAID sets for storage. RAID helps in creating a backup of your data in the storage array. Now, if, due to any reason, the disk in which the data is stored undergoes failure, it won’t have any impact on the proper function of the operating system. RAID makes your system tolerant of such faults.
Continue using the system: As all the data you store in RAID is also stored in one of the backup drives, you will not have any issues using the system if one of the drives you have stored data fails. You will have enough time to find a replacement for the drive that has stopped working.
Parity check: When you use RAID to store data on your system, you improve its ability to look for issues that are still in an early stage but can cause the system to crash if not adequately dealt with.
Faster transmission: With RAID, the speed of reading and writing data is very fast as both these processes rake place at the same time.
Common causes of RAID failures
We have listed down a few very commonly occurring reasons that lead to RAID system failures:
- The system is unable to boot
- Disk order error
- RAID data is missing
- Dynamic disk’s database is either corrupted or missing
- Damage to DBR or MBR
- The rebuilding of RAID fails in the middle
- Information related to partition is nowhere to be found
- Damage to RAID cabinet or card causes the system to crash
- The reconstruction of RAID is successful, but there is a problem is starting the order or finding the partition
- Disk replacement failure causes the system to crash
Now that you know of the causes of a broken RAID set, it is crucial to be aware of the steps you need to perform before using any method to start the actual recovery. First, you should stop using the RAID array as soon as you know that it broke. If you still go on and perform a data recovery method of your own, do it at your peril. You may have to say goodbye to your valuable data, forever, if you do this. To put it in simple words, the longer you use a RAID set after it has failed or broken the tougher job data recovery job it will become. If you can’t put a complete full stop on the usage, at least reduce it until things are sorted.
The next thing to do is to detach all those hard drives currently connected to the RAID set. Make sure you unplug or turn off the broken RAID set before performing the disconnection task. Store these drives in a safe environment.
How to recover data from RAID?
One of the best ways of recovering data from a broken RAID set is using a data recovery tool. The harder job here is to find the right data recovery software for your needs. Make sure you choose a data recovery solution that can help you get the job done even if you are an inexperienced user. A powerful tool that comes with an easy-to-use application can help you get your data back without delay.
You can use one of these tools when you carelessly delete some files stored in RAID. You go on and clear them from the recycle bin as well. These tools are also handy for situations when you accidentally delete partitions when you are managing RAID disks.
Data recovery software can be used when there is damage caused to one or more partitions by a system crash, virus attack, or others. When you reformat a disk or a partition inside it, you get rid of all the stored data. You won’t be able to access this data after you wrongly format a disk or its partition.
Data recovery tools also come in handy in situations in which you mistakenly delete a partition. There are also situations when the actual reason for a partition loss is not found, but you eventually have to deal with data loss as a result of that.
If you aren’t able to get your data back even after using the best available tools, you might look for companies that provide RAID data recovery in Perth, Melbourne and other cities. Sometimes, you need expert intervention in these situations. Also, leaving this job to professionals ensures that you won’t have to deal with any issues.
