subject: What Is Raid, Possible Reasons Of Data Loss And How To Raid Recovery Done? [print this page] Many individuals and professionals often mistakenly believe that the lost data is permanently destroyed and it is therefore impossible to recover. Too little information available on this subject fueling confusion related to data recovery.
I pose the problem differently. For 15 years our engineers are addressing the problems of data loss and get ahead. They concluded that the data is recoverable in most cases, whatever the circumstances.
If you lose data, immediately ask the advice of a qualified expert on what to do before starting anything.
70% of our customers believe their data loss from a hardware problem, the only way to
Data Recovery is to return to their hard drive recovery lab. However, we find that only 51% of cases of data loss due to hardware problems. In other words, in reality, the problem could be solved with our recovery services remotely via a modem or Internet, even with recovery software.
What are different types of RAID?
In a RAID 0 (striping), the data are scattered among the drives, which improves performance. However, there is no data redundancy, which implies that if one drive fails, the others become unusable. The current breakdown:
No electrical or mechanical shock on one disc
Configuration Error
Loss of RAID configuration
RAID 1 allows for two hard drives in mirroring. Each disk is a clone of another.
If one drive fails, the second is a backup date of the first. The current breakdown:
No Problem setup RAID
failure of two hard drives (eg over voltage on the machine)
NB. In the case of a RAID 1, treatment is the same as a failure "classic".
It is in this case we send two hard drives to increase the chances of successful data recovery.
With over 15 years of experience and nearly 235 engineers, experts, Stellar offers the best solutions to solve complex RAID disasters.
Recover data from hard disk is more complex in cases where it is part of a RAID configuration.
When a failed drive is replaced, the data removed from the matrix must be regenerated on the new record by RAID controller: This is the reconstruction. The matrix is very vulnerable.
RAID systems are susceptible to the same flaws as the hard drives simple viruses, logic problems, human error, physical destruction. It adds to it many elements of complexity that can cause loss of configuration registry server reconfigurations accidental RAID, the RAID controller failures, etc..
1. Remote retrieval: If one of the RAID disk is damaged, we can operate remotely through a secure Internet connection. This is the most rapid, convenient and economical data recovery.
2. Recovery Laboratory: In cases where multiple disks are down, we work in our clean room to ensure the recovery of your critical data.
3.Onsite Recovery: When data volumes are large, extremely sensitive, or the retirement of online media would lead breaks too important, our teams move your site to achieve recovery.
By using the services Stellar Data Recovery, you know exactly recoverable data before you commit to the actual recovery RAID data. Recovery of RAID require a level of expertise of a very high level. Make sure the provider you choose provides this level of expertise. Most providers do not have the necessary resources and put your data at risk.
