DATA STORAGE INTEGRITY VALIDATION

摘要

Embodiments of the present disclosure are directed to, among other things, validating the integrity of received and/or stored data payloads. In some examples, a storage service may perform a first partitioning of a data object into first partitions based at least in part on a first operation. The storage service may also verify the data object, by utilizing a verification algorithm, to generate a first verification value. In some cases, the storage service may additionally perform a second partitioning of the data object into second partitions based at least in part on a second operation. The second partitions may be different from the first partitions. Additionally, the archival data storage service may verify the data object using the verification algorithm to generate a second verification value. Further, the storage service may determine whether the second verification value equals the first verification value.

1. A computer-implemented method, comprising:
under the control of one or more computer systems configured with executable instructions,
receiving a request to store a data object comprising a first plurality of partitions, each partition of the first plurality of partitions having a first partition size selected by a requestor associated with the request;verifying the data object using a data verification algorithm to generate a first verification value based at least in part on the first partition size;storing the data object and the first verification value;partitioning the data object into a second plurality of partitions, each partition of the second plurality of partitions having a second partition size different than the first partition size, the second partition size selected by the data verification algorithm; andverifying the data object using the data verification algorithm by at least:
generating a second verification value based at least on the second partition size; andcomparing the second verification value with the first verification value.
