RAID data recovery | What is RAID Data Recovery

RAID data recovery

RAID data recovery is the process of restoring and recovering data from a RAID storage architecture or infrastructure.

Uses a combination of automatic and manual data recovery to extract and replicate data from one or more RAID drives and storage devices. RAID data recovery can be implemented in both hardware and software RAID.

Techopedia describes restoring RAID data

RAID data recovery is fundamentally different from the data recovery process because the RAID storage architecture uses a unique and complex data storage and recovery system. RAID data recovery is possible for any RAID level including RAID 0, 2, 3, 4, 5, 6, 7, and 10. Often recovery fails due to technical faults such as;

  • Damaged hard drives
  • Rogue controllers
  • Data is overwritten
  • Application/software crashes
  • Rewriting

Typically, a RAID restore rebuilds the entire RAID storage unit according to the first or last known optimal settings and configuration. To successfully replicate data, the user/software needs to know how to configure RAID at the hardware, software, and firmware levels. Determining the correct RAID array is one of the most important tasks in RAID recovery.

Best RAID Recovery Software – EaseUS Data Recovery Wizard

Choosing a professional RAID recovery software to recover data from a RAID drive helps tremendously! The EaseUS Data Recovery Wizard gives you a complete Windows RAID data recovery solution. Whether it’s RAID 0, RAID 1, RAID 5 or RAID 10, EaseUS RAID recovery software will help you recover data from any RAID hard drive as long as your computer system can recognize it.

How to recover data from a Raid hard drive

With this software you can recover files from Raid Hard Drive in 3 ways;

Scan Disk > Preview and select DesiRaid File > Restore Data.

Now follow these steps to restore RAID data using the EaseUS Data Recovery Wizard:

Step 1. Scan to Raid Drive

Select the RAID drive from which you want to restore data, then click “Scan.” Wait for the scanning process to finish, and the deleted files will be displayed one by one.

  1. Find the missing RAID file and try first

You can use “filter” as a quick check to find deleted or missing files. Alternatively, you can search for missing RAID drive files by file name or file extension.

  1. Recover lost raid drive files

Select the Raid file and click “Recover”. Please request to save these files in another safe location.

Useful in Raid

In general, RAID uses multiple disks running in parallel to increase overall system performance for computer users, especially server users. It also has the following advantages;

  • Better data protection
  • Excessive fault tolerance
  • Increased parity testing and routine testing for potential system crashes.
  • Reading and writing together.

However, while RAID provides excellent data protection, RAID hard drives are prone to data loss. System crashes, virus attacks, power outages/power surges or other unexpected errors can cause data to be lost on your RAID drive or hard drive. You might think raid data recovery is hard. With the right RAID recovery software, you can easily and safely recover data from your RAID hard drive.

Recovering from a RAID 5 drive failure

RAID 5 protects data with parity data distributed across all member drives. If one disk fails, data can be accessed from other disks.

About this work

If a disk fails in a RAID 5 disk array, the status of the disk array is Degraded. The disk architecture remains efficient because data from a failed disk can be reconstructed using data from other parcels and disks. If there is a hot redundancy, the controller can automatically recreate the data on disk. If there is no spare disk, you need to replace the failed disk, and then restart the build.

Follow these steps to begin recovery;

  1. Type ipr config and run the ipr config tool.
  2. Select Use Disk Unit Recovery.
  3. Select Rebuild Disk Unit Data.
  4. Select the disk that you want to recreate, and then press Enter.
  5. Press Enter to rearrange the data. If you want to recreate the information, type q to finish.

RAID 6 recovery

Basic RAID principles include a standard RAID configuration for fragmenting data across storage using mirroring, stripping or parity.

RAID 6 is one of the options for systems that cannot afford to lose data. RAID 6 is less efficient (because each parcel is counted separately) and instead parcel data is written to one of two disks. This probably means that it takes at least 4 discs to create such an attack, and it can support 2 disc spins at a time.

However, because there are multiple drives in a RAID 6 array, downtime can be significant.

At the same time the architecture offers no protection against data loss due to catastrophic failures, file infections, multidisk corruption and so on

RAID 6 array failure symptoms and causes

As mentioned above, RAID 6 offers no protection against data loss due to accidents, file infections, multidisk corruption, and so on.

These are the most common scenarios where you need to rebuild your attack;

  • No RAID slot
  • Your RAID controller is unresponsive.
  • Your server crashed
  • Electrical problems: Voltage is low
  • Damaged or expired disks
  • You accidentally lost files on your disk.

The most common RAID 6 failure is due to a disk failure or a URE fault. This means that for every 20 million sectors the disk fails to read one of those possibilities, which means the controller will detect an error and the recovery of RAID 6 data will stop

However, you can still recover your data with the Disk Internal RAID recovery program.

Phased access to RAID 6 data

  • If a disk in the array fails, start by creating two images of that particular disk.
  • Download and install Disk Internal RAID Recovery to recover RAID 6.
  • Select the array type and location.
  • Wait until the program automatically recognizes your disk configuration or file list. Check your preview file to make sure you get what you want and that it is in the correct format. It is recommended to have images larger than 2MB in your data for complete data integrity.
  • Purchase a license for the Windows RAID recovery software and continue the data extraction process.
  • Congratulations Now RAID 6 is rebuilt and safe!
