Erasure Coding

Erasure coding is a data protection technique that breaks data into smaller pieces, adds extra information, and distributes these pieces across different storage locations. If some pieces are lost or corrupted, the original data can still be reconstructed using the remaining pieces and the extra information. This approach is especially useful for ensuring data reliability and integrity in systems like cloud storage, allowing for efficient recovery from failures without needing full duplicates of the data. Essentially, it enhances data resilience while using storage space more efficiently.
