Abstract: 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.

Abstract: Embodiments of the present disclosure are directed to, among other things, managing inventory indexing of one or more data storage devices. In some examples, a storage service may store an index associated with archived data. Additionally, the storage service may receive information associated with an operation performed on the archived data. The storage service may also partition the received information into subsets corresponding to an identifier. In some cases, the identifier may be received with or otherwise be part of the received information. The storage service may also retrieve at least a portion of the index that corresponds to the subset. Further, the storage service may update the retrieved portion of the index with at least part of the received information. The updating may be based at least in part on the subsets.

Abstract: Methods and systems are provided herein to allow efficient management of data flowing in and out of an archival data storage system. In an embodiment, storage entities keep very little state information in memory to provide higher throughput. Further, storage entities may send data in large chunks to facilitate high throughput. Techniques such as batching and coalescing may be used by various storage entities to provide efficiency.

Abstract: A request to retrieve a persistently stored data object is received, the request including a data object identifier that encodes at least storage location information and validation information related to the data object. The data object is retrieved using at least the storage location information to form a retrieved data object, and validation is performed using at least the validation information.

Abstract: Methods and systems are provided herein that facilitate cost-effective and reliable data identification in an archival data storage system. In an embodiment, a data object stored in an archival data storage system is identified by a data object identifier which encodes storage location information that may be used to locate a data object stored in an archival data storage system that reduces the cost to store a global index. The data object identifier may also encode policy information such as access control information usable for validating subsequent access to the data object, payload validation information such as size and digest usable for verifying the integrity of the payload data, metadata validation information such as error-detection codes usable for validating integrity of the data object identifier and other information.
