redundant RAID array. Rebuild is usually performed in the background while applications are accessing data in the

redundancy
Maintaining duplicates for any given component in a system so the system can automatically replace a failed
component with a working substitute. A parity RAID array's members are redundant since surviving members may
collectively replace the data from a failed hard disk.
