  • Patent number: 10289481
    Abstract: Techniques described and suggested herein include various methods and systems for verifying integrity of redundancy coded data, such as erasure coded data shards. In some embodiments, a quantity of redundancy coded data elements, hereafter referred to as data shards (e.g., erasure coded data shards), sufficient to reconstruct the original data element from which the redundancy coded data elements are derived, is used to generate reconstructed data shards to be used for checking the validity of analogous data shards stored for the original data element.
