Which storage data protection technique provides space-optimal data redundancy to prevent data loss against multiple disk drive failures?
Erasure coding is a data protection technique that provides space-optimal data redundancy to prevent data loss against multiple disk drive failures. It works by breaking data into fragments, expanding and encoding it with redundant data pieces, and storing it across a set of different locations or storage media. This method ensures that if some drives fail, the lost data can be reconstructed from the remaining fragments, making it more efficient in terms of storage space compared to traditional RAID methods.
A Erasure Coding: Provides space-optimal data redundancy to prevent data loss against multiple disk drive failures
Correct is A
Erasure Coding: Provides space-optimal data redundancy to prevent data loss against multiple disk drive failures. Coding information is calculated from stored data.
