Abstract: Efficient cloud storage systems, methods, and media are provided herein. Exemplary methods may include locating a Merkle tree of a stored object on a deduplicating block store, comparing an object at a source location to the Merkle tree of the stored object, determining changed blocks for the object at a source location, and transmitting a message across a network to the deduplicating block store, the message including the change blocks and Merkle nodes that correspond to the change blocks.

Abstract: Cloud storage services can be used to facilitate secondary backup and disaster data recovery without the need for specialized backup servers at the secondary location or cloud storage service. Backup data streams are transferred to a cloud storage service. In addition to the backup data streams, backup metadata is generated for each backup data stream. The backup metadata is adapted to configure a backup server to retrieve and access data in the backup data stream. The backup metadata is also transferred to the cloud storage service. To access data from the backup data stream, a recovery backup system is connected with the cloud storage service. Backup metadata is transferred from the cloud storage service to the recovery backup system. The recovery backup system is updated with the backup metadata, which configures the recovery backup system to retrieve and access data in the backup data stream.

Abstract: A log structured content addressable deduplicated data storage system may be used to store deduplicated data. Data to be stored is partitioned into data segments. Each unique data segment is associated with a label. The storage system maintains a transaction log. Mutating storage operations are initiated by storing transaction records in the transaction log. Additional transaction records are stored in the log when storage operations are completed. Upon restarting an embodiment of the data storage system, the transaction records from the transaction logs are replayed to recreate the state of the data storage system. The data storage system updates file system metadata with transaction information while a storage operation associated with the file is being processed. This transaction information serves as atomically updated transaction commit points, allowing fully internally consistent snapshots of deduplicated volumes to be taken at any time.

Abstract: The cloud storage services are extended with a cloud storage service access protocol that enables users to specify a desired storage tier for each data stream. In response to receiving storage tier specifiers via the protocol, the cloud storage service performs storage operations to identify target storage devices having attributes matching those associated with the requested storage tier. The cloud storage service stores a data stream from the storage client in the identified target storage device associated with the desired storage tier. Storage tiers can be defined based on criteria including capacity costs; access latency; availability; activation state; bandwidth and/or transfer rates; and data replication. The cloud storage service protocol allows data streams to be transferred between storage tiers, storage devices to be activated or deactivated, and data streams to be prefetched and cached. The cloud storage services may charge storage clients based on storage tier use and associated operations.

Abstract: A data virtualization storage appliance performs data deduplication transformations on the data. The original or non-deduplicated file system is used as shell to hold the directory/file hierarchy and file metadata. The data of the file system is stored by a separate data storage in a transformed and deduplicated form. The deduplicated data store may be implemented as one or more hidden files. The shell file system preserves the hierarchy structure and potentially the file metadata of the original, non-deduplicated file system in its original format, allowing clients to access file metadata and hierarchy information easily. The data of a file may be removed from the shell file system and replaced with a data layout that specifies the arrangement of deduplicated data segments needed to reconstruct the file data. The data layout associated with a file may be stored in a separate data stream in the shell file system.

Abstract translation: 数据虚拟化存储设备对数据进行重复数据删除转换。 原始或非重复数据删除的文件系统用作shell来保存目录/文件层次结构和文件元数据。 文件系统的数据通过单独的数据存储以转换和重复数据删除的形式存储。 重复数据删除的数据存储可以被实现为一个或多个隐藏文件。 shell文件系统保留原始格式的原始，非重复数据删除的文件系统的层次结构和潜在的文件元数据，从而允许客户端轻松访问文件元数据和层次结构信息。 可以从shell文件系统中删除文件的数据，并替换为指定重建文件数据所需的重复数据删除数据段的排列的数据布局。 与文件相关联的数据布局可以存储在shell文件系统中的单独的数据流中。

Abstract: Synthetic backups are created without accessing previous backup data or retrieving backup data from a cloud storage service. A backup system provides two or more backup data sets to a cloud spanning storage interface for storage in deduplicated form as label maps and data segments in a cloud storage service. A specification defines portions of two or more previous backup data sets to be copied into the synthetic backup. Labels corresponding with the specified portions of previous backup data sets are identified and added to a new label map to create a deduplicated synthetic backup. The completed label map is transferred to the cloud storage service. To provide access to the synthetic backup, the cloud spanning storage interface reconstructs all or a portion of the synthetic backup from the new label map and the data segments created during deduplication of previous backup data sets.
