Don’t Hesitate When It Comes To RAID Recovery
RAID drives are very popular as data storage devices for companies as they offer large amounts of storage that is, in general, pretty reliable. When a RAID drive malfunctions however you may feel that you have lost everything when you find that you are unable to get to important information that is stored on there.
When you purchase your RAID system you should be aware of the different RAID architectures and configurations that are available. RAID 0 systems will stripe the data onto multiple drives. This is the least effective RAID system and the hardest to recover because there is no fault tolerance within the system. If two drives are used and one of them crashes and becomes inaccessible then you will lose access to all of your information. A RAID 1 system utilises mirroring, which essentially writes two copies of each file, one onto each of two RAID drives. This system is highly fault resistant, but it does not make the best use of the storage space available.
RAID 5 is the most popular RAID system as it utilises multiple disks, with at least three disks being required for the system to work properly. RAID 5 uses striping and parity information in order to utilise storage effectively and to add robustness to the system.
When a RAID system fails it is sometimes possible to attempt to recover the information that is on the damaged drive yourself, but this can all to easily turn out to be a false economy as there can be further problems caused during a partial rebuild in a RAID 5 system especially if the failure was due to a faulty controller card or operating system. If you are going to attempt a system rebuild contact us first. If the rebuild does not complete correctly your data could have serious corruption issues. If a rebuild does go wrong we can recover the data in most circumstances but phone us first for free advice on your best way forward. We also have great experience in Virtual Raid systems, if your virtual raid system fails contact us immediately. Virtual systems normally contain four layers of virtualization, namely the RAID layer, IVM layer, Virtual SCSI layer, and file system layer. If any layer is corrupt, recovery can be tricky. It is like peeling layers of an onion. There are also additional considerations that you have to take into account if attempting to repairing a virtual raid system yourself that include volume matching, configuration matching in order to avoid further, and more serious, disk failure.
There are also many cases where it is actually user error that causes the data on RAID drives to become inaccessible. Often these issues are caused by software and permissions issues and so access to the data can be restored to the drive by manipulating the software. Should the affected drive be physically damaged or the data on it corrupted beyond the software interface.
Therefore it would be in your best interest, in the event of a RAID failure, to immediately consult with one of our RAID recovery specialists. They will be able to provide you with a quick initial assessment of your drives and will be able to provide you with a quote and projected recovery timescales in most cases.
Our RAID recovery specialists will create images of your disks so that they can perform the recovery without endangering your original disks. Also, we have such a high data recovery rate that if we are not able to recover your data, then we will not charge you for our services. So make us the first port of call if your RAID drives need recovering.
