    Abstract: Aspects of a data environment, such as the creation, provisioning, and management of data stores and instances, are managed using a separate control environment. A user can call into an externally-facing interface of the control environment, the call being analyzed to determine actions to be performed in the data environment. A monitoring component of the control plane also can periodically communicate with the data environment to determine any necessary actions to be performed, such as to recover from faults or events in the data environment. A workflow can be instantiated that includes tasks necessary to perform the action. For each task, state information can be passed to a component in the data environment operable to perform the task, until all tasks for an action are completed. Data in the data environment can be accessed directly using an externally-facing interface of the data environment, without accessing the control plane.

    Abstract: A computer system, such as a data storage system, implements techniques for segregating and controlling access to data stored in multiple regions. In some embodiments, redundancy coded shards generated from the data and stored in durable storage of a data storage system is allocated across multiple regions, but in a fashion that prevents actors with access to regions outside that of a “home” region from recovering a sufficient number of unique shards to regenerate the data represented thereby. In some embodiments, encryption is used to segregate the data by encrypting the generated shards, then storing the cryptographic information on or otherwise controlling access on hosts or other devices of only the home region.

    Abstract: Techniques described and suggested herein include systems and methods for storing, indexing, and retrieving original data of data archives on data storage systems using redundancy coding techniques. For example, redundancy codes, such as erasure codes, may be applied to archives (such as those received from a customer of a computing resource service provider) so as allow the storage of original data of the individual archives available on a minimum of volumes, such as those of a data storage system, while retaining availability, durability, and other guarantees imparted by the application of the redundancy code. Sparse indexing techniques may be implemented so as to reduce the footprint of indexes used to locate the original data, once stored.

    Abstract: Reliable and efficient storage and reconstruction of secure data files is provided. Encrypted fragments are generated by exclusive-OR (XOR) based erasure-encoding and XOR encryption of data files. At least some of the encrypted fragments, and preferably at least two copies of such encrypted fragments, are stored at two or more locations, such as but not limited to two or more servers in two or more regional storage systems. Fragments are retrieved from one or more of the multiple locations and the original data file is reconstructed, even if different encryption techniques have been used. If not enough valid fragments from that original data file can be identified then hash values, checksums, seeds, and other techniques may be used to distinguish files and to identify related or identical files which may be used to reconstruct the data file.

    Abstract: A processing device receives a request to identify whether a file is a complete file. The processing device determines a first size of the file. The processing device determines whether the first size satisfies a size criterion. The processing device determines that the file is a complete file responsive to the determination that the first size satisfies the size criterion.

    Abstract: One or more grids of redundancy coded shards, such as those stored or otherwise represented on grid encoded storage systems, are combinable or extensible. For example, a generator matrix of a redundancy code may be configured so as to have a sufficient number of fields to generate a grid. The generator matrix may initially be used to generate smaller grids, which can be combined into the target grid without re-encoding most or all of the data represented thereon. In some cases, vertically derived shards of the input grids may be combined using, e.g., matrix addition, which may then be directly allocated to the target grid, while data shards and horizontally derived shards may be allocated to the target grid with no further transformation.
