Definition – What does RAID Data Recovery mean?
The practice of recovering and restoring data from a RAID storage architecture or infrastructure is known as RAID data recovery.
It extracts and restores data from one or more RAID disks and storage components using a combination of automatic and human data recovery procedures. RAID data recovery is possible on both hardware and software RAID systems.
Techopedia explains RAID Data Recovery
The RAID storage design uses a unique and sophisticated technique of storing and extracting data, which makes RAID data recovery different from typical data recovery processes. Any RAID level, including RAID 0, 2, 3, 4, 5, 6, 7, and 10, can have their data recovered. Technical errors, such as the following, frequently necessitate recovery.
Hard disk failure
Controllers with flaws
Data is overwritten, and the application/software is corrupted, which necessitates reformatting.
In most cases, RAID recovery necessitates restoring all RAID storage arrays to their original or last known good settings and configuration. To properly retrieve data, the individual/software must understand the RAID configuration at the hardware, software, and firmware levels. The RAID recovery technique requires you to identify the correct RAID array.
Before you start your RAID recovery
Take into account the following:
If one of the RAID 5, RAID 6, RAID 5E, or RAID 0+1 member disks is physically damaged (makes strange sounds, such as clicking or repeated spin-up and spin-down sounds), don’t use it for recovery.
If you can’t avoid utilizing a physically damaged disk for RAID 0 recovery, try creating a disk image file with ReclaiMe Free RAID Recovery software’s Create disk image under Disks on the toolbar.
If you have a hardware RAID, make sure the member disks, connectors, and controller ports are clearly labeled so that the original setup may be reassembled if necessary.
Disconnect the array member disks from the RAID controller and connect them to a non-RAID controller as separate/standalone drives. To reconstruct RAID settings, ReclaiMe Free RAID Recovey has to access the drives separately.
Prepare a free disk space equivalent to the quantity of data you plan to recover once the RAID parameters are restored if you plan to recover data.
How to recover RAID
ReclaiMe Free RAID Recovery program should be installed and launched.
Use the Disks button to open or create disk image files of the member disks if necessary.
Choose the type of array you want to use.
Select a minimum of two devices from the list for RAID 0, then click Start RAID 0.
Select all available member drives for RAID 5 and click Start RAID 5. It is necessary to have a minimum of two disks. RAID 5 with one disk missing can be recovered using ReclaiMe Free RAID Recovery software.
Select all available member disks and the appropriate RAID type under Other RAIDs for RAID 0+1, 1+0, RAID 5E, or RAID 6.
Wait until the software has finished detecting the arguments before proceeding. It can take anywhere from a few minutes to several hours (learn why). When either the Scan Progress or the Confidence fields are completely filled, the process is finished. It’s worth noting that Scan progress is usually increasing, although Confidence may be decreasing.
All of the settings have already been restored at this point. Then you have the option of selecting:
To recover data, run ReclaiMe. If the ReclaiMe File Recovery program is already installed on the computer, it starts in RAID recovery mode and shows the array’s partitions. If you don’t already have ReclaiMe, you’ll be prompted to download the software.
Save your layout as an XML file. Save the XML file with the restored array parameters. Note that you can open this file in ReclaiMe File Recovery software and use ReclaiMe RAID recovery mode to recover data from the array.
Use it in conjunction with other data recovery applications. Provides step-by-step instructions for transferring retrieved parameters to a number of well-known data recovery programs. It’s important to remember that the instructions were written specifically for each RAID configuration, and you should follow them to the letter. The instructions can be copied to the clipboard using the Copy to the clipboard button if necessary.
