RAID recovery refers to the process of retrieving data from a RAID (Redundant Array of Independent Disks) system when it becomes inaccessible or encounters data loss due to various reasons. RAID arrays combine multiple hard drives into a single logical unit, providing data redundancy, improved performance, or both, depending on the RAID configuration.
RAID recovery becomes necessary when one or more drives in the array fail, there is a RAID controller malfunction, accidental data deletion occurs, or there are issues with the RAID configuration itself. During RAID recovery, specialised data recovery techniques and tools are employed to reconstruct the data from the remaining functional drives and recover it to a usable state.
