Data striping with parity
WebErasure coding (EC) is a method of data protection in which data is broken into fragments, expanded and encoded with redundant data pieces and stored across a set of different locations or storage media. WebAug 17, 2024 · Striping partitions help spread data over multiple disk drives. Disk mirroring and disk striping can also be combined in a RAID array. Important: RAID is not a backup and does not provide protection against data loss caused by malicious attacks, file system corruption, virus, malware or ransomware. RAID Levels Explained

WebIn the above example, Data 1, Data 3 and Parity 2 from stripe one is used to rebuild Data 2. Data 4, Parity 1 and Data 6 are used to rebuild Data 5 in the second stripe. Data 7, Parity 2 and Data 9 are used to rebuild Data 8 in the third stripe. Once the RAID array is virtually reassembled, the file system or volume is scanned for corruption.
