What is RAID Data Recovery?

This is the process of recovering data from a RAID storage infrastructure or architecture and then restoring it.  It is an acronym for Redundant Array of Inexpensive Disks.  It can also mean Redundant Array of Independent Disks.  In layman terms, this means that it is a collection of disk drives that are categorized together.  They are created on a pre-set configuration, they are accessed to give data striping, mirroring, or redundancy.  In some situations, it can be a combination of any of the three.

RAID data recovery uses a combination of manual and automated data recovery processes to extract and then restore data.  It can be implemented on both software-and hardware-based RAID.  There is a difference between the standard data recovery UK and RAID.  With RAID they use a complex, unique method of extracting and storing the data. 

There are several levels of RAID, including:

  • 0
  • 2
  • 3
  • 4
  • 5
  • 6
  • 7
  • 10

The RAID levels that are mainly used are the levels 0, 1, and 5.

Some of the reasons that you may need to use RAID is generally due to technical errors like:

  • Reformatting
  • Faulty hard disk drive
  • Software/application corruption
  • Data overwritten
  • Faulty controllers
  • Human error
  • Power outages
  • Abrupt system shutdown

When this type of data recovery is required, it will include the reconstruction of all the RAID storage arrays to the last known good configurations or settings, or the original settings.  To successfully retrieve the data, the software/individual will have to know the RAID configuration at the firmware, hardware, and software level.  An essential part of the RAID data recovery process is being able to identify the correct RAID array.

Generally, with the RAID is damaged, the data is lost because the RAID volume is inaccessible.  To get it back you will have to rebuild or reconstruct the RAID configuration as mentioned.  Many users find that this is difficult to do but there is data recovery UK software that can help the user to simplify the process.  You can also take it to a professional IT person and have them do the recovery.

There are many different advantages of using RAID.  One advantage is that it uses multiple disks, which work together to increase the overall performance of the system.  It also offers higher data security, and simultaneous writing and reading processes. 

Hardware- and software-RAID

  • Hardware: This type uses a specialized physical controller to maintain information about your hard drives.  It also regulates the data access and write functions for the volume.
  • Software: This is where the regular drive controller is used.  The software then oversees the drives that are in the array.  This is an inexpensive way to execute RAID data storage.  Although less expensive, it is also can be a lot slower because it places a big burden on memory resources and the CPU>

Conclusion

When you are doing data recovery, you can use software to fix the issues, or you can take it to an IT.  If you are not knowledgeable about working on computers, you should have it professionally fixed.
