Although RAID systems are now larger, more robust and have a far greater range of graphic and sound storage options, their complexity means that crashes can be more catastrophic than previously.
The good news is that RAID data recovery is not usually a serious problem - provided you engage the services of a reliable and professional RAID data recovery service.
The failure of such data systems needs to be treated as a top priority and a good service will ensure that the problem is diagnosed as quickly as possible, to determine whether it can be dealt with in their computer lab or on site.
If RAID data recovery needs to take place at the lab, technicians will engage all media that is still accessible in order to make a raw copy of its data and place it on to new media.
It will then be possible to deduce the precise nature of the data loss.
During these tests the data recovery service will also run tests on the systems components to determine if there is any physical damage present, and to what extent.
RAID data recovery often requires the replacement of broken components in the sterile environment of a computer lab, alongside the use of specially-constructed software and hardware devices to recreate the raw data image, through close examination of the failed servers lower-level data sectors.
It is essential for technicians to work out which volumes of data are "striped" across multiple drives on the RAID system and then to implement the correct solutions to file system structures, allowing access to the data.
Servers with a large number of drives are carefully "destriped" and placed in new media, enabling repairs to the file system and the extraction of missing data files.
Upon the successful recovery of data, a good service will also create new file lists and check the validity of all the information.
