You may need to perform some data recovery incase this happens for you to get back your dataīefore you can start any recovery on RAID, first consider the following factors: However this doesn’t mean that the RAID disks are fully fault tolerant, meaning that there is a possibility of the drives crashing. Since multiple disks increase the mean time between failures (MTBF), storing data redundantly also increases fault tolerance. RAID (redundant array of independent disks originally redundant array of inexpensive disks) provides a way of storing the same data in different places (thus, redundantly) on multiple hard disks (though not all RAID levels provide redundancy).īy placing data on multiple disks, input/output (I/O) operations can overlap in a balanced way, improving performance. For raid cases, it’s best to consult a data recovery expert. Images of all the disk should be taken before attempting anything. Since raid is very delicate, it’s not advisable to attempt to recover without the necessary skills, this is because any mistake or wrong rebuilding could render the data unrecoverable. Identifying the correct RAID array is an essential part of the RAID recovery process. The individual/software must know the RAID configuration at the hardware, software and firmware level to successfully retrieve data. RAID recovery generally requires reconstruction of all RAID storage arrays to original or last known good settings and configuration. RAID data recovery can be for any of the RAID levels, some of the most common include RAID 0, Raid 1, Raid 5, Raid 6, Raid 10, Raid 50, Raid 60, Raid 5E, Raid 5EE. RAID data recovery is unique from the normal data recovery processes as the RAID storage architecture uses a unique and complex method of storing and extracting data. RAID data recovery can be implemented on both hardware- and software-based RAID. RAID data recovery is the process of retrieving and restoring data from a RAID storage device such as NAS, Servers, SAN etcĭata recovery experts use a combination of automated and manual data recovery processes to extract and recover data from one or more RAID drives and storage components.
