Summary: RAID data recovery is a process of restoring lost or deleted data from a broken, crashed, degraded, formatted, or corrupt and inaccessible RAID array volume(s). In this guide, we will take you through a step-by-step guide to perform RAID 0, RAID 5, and RAID 6 data recovery in your organization safely—without using any hardware RAID controller.
RAID arrays are an advanced storage solution that assures data safety in an organization and helps maintain business continuity. However, this doesn’t mean RAID-based storage solutions such as NAS are failure-proof.
While some popular RAID configurations like RAID 5 and RAID 6 can withstand up to one or two disk failure respectively, they can’t protect against logical failures often caused by hardware or software failure and human errors.
Accidental deletion, virus or malware infection, sudden system shutdown, power surges, controller malfunction, disk errors, etc. are some common errors that can lead to data loss from a Redundant Arrays of Independent Disks (RAID).
A common misconception and popular belief about RAID arrays is that the data on RAID doesn’t require backup. But the fact is that RAID is nor a backup neither an alternative to backups, and data on RAID requires backup.
RAID data recovery is a tedious process and requires expert solutions and help. In this guide, we will help you get back every bit of recoverable data from popular RAID arrays without using any hardware RAID controller.
The software we are using is Stellar Data Recovery Technician—by Stellar®, a pioneer in providing expert data care solutions with over 25 years of experience.
This powerful RAID data recovery tool can reconstruct a broken or corrupt RAID for data recovery even if the critical RAID parameters—required for RAID rebuild—are unknown.
To recover lost or deleted data from a missing or deleted RAID volume, follow these steps:
Rebuilding a broken, crashed, or corrupt RAID is nearly impossible. A failed RAID requires reconstruction from scratch after formatting all RAID drives in the array. However, before rebuilding your broken RAID array, you can recover your data from the RAID by using Stellar Data Recovery Technician.
The powerful RAID data recovery software can rebuild virtual RAID—even if RAID parameters are unknown or not provided—and facilitates data recovery from a failed, broken, and crashed RAID 0, RAID 5, and RAID 6 arrays.
Follow these steps to recover data from a logically broken RAID,
TIP: Choose ‘Monitor Drive’ to check the SMART status and disk health of your connected RAID drives. If the health is poor or SMART status displays a warning sign, immediately stop and clone the affected disk.
IMPORTANT NOTE: In case the RAID volume is not displayed in the list, skip to the next section for the Steps to recover data from missing RAID volume.
Sometimes, due to severe corruption or logical error, you may lose access to one or more RAID partitions in an array. In such a case, you don’t have many options but to reformat the lost volume in order to regain access to it. However, before regaining access, you can leverage the Stellar Data Recovery Technician to recover data from the lost partitions,
After launching Stellar Data Recovery Technician, choose files to recover and then select ‘RAID Recovery.’
RAID data recovery is possible with backup and enterprise RAID data recovery solution such as Stellar Data Recovery Technician. Data loss from RAID can happen due to reasons such as accidental deletion, malware or virus infection, power surge, and more.
In such situation, you can utilize your RAID backups to restore lost files and data. And in the absence of backup, use a powerful DIY RAID data recovery software from Stellar®.
The software can help you recover deleted files from RAID 0, RAID 5, and RAID 6 arrays and facilitates data recovery from a degraded, crashed, failed or corrupt RAID arrays.
This DIY RAID recovery software works even when you don’t know or forget the critical RAID parameters required for RAID reconstruction. Leverage the software in your organization to recover data lost from a RAID 0, RAID 5, and RAID 6 array without those expensive hardware RAID controllers with complete privacy.
