RAID data recovery is the process of recovering and restoring data from a RAID storage architecture or infrastructure.
It uses a combination of automated and manual data recovery processes to extract and restore data from one or more RAID drives and storage components. RAID data recovery can be implemented on both hardware- and software-based RAID.
Techopedia Explains RAID Data Recovery
RAID data recovery is different from standard data recovery processes as the RAID storage architecture uses a unique and complex method of storing and extracting data. RAID data recovery can be for any of the RAID levels including RAID 0, 2, 3, 4, 5, 6, 7 and 10. Recovery is usually required due to technical errors such as:
- Faulty hard disk
- Faulty controllers
- Data overwritten
- Application/software corruption
- Reformatting
RAID recovery generally requires reconstruction of all RAID storage arrays to original or last known good settings and configuration. The individual/software must know the RAID configuration at the hardware, software and firmware level to successfully retrieve data. Identifying the correct RAID array is an essential part of the RAID recovery process.
