摘要： A method and system for improving performance with single-instance-storage volumes by leveraging data locality is provided. A client provides a set of fingerprints generated from data segments to be saved to a single-instance storage volume and receives the information on whether a data segment exists on the single-instance storage volume and where it is stored if a data segment exists. Based on its received information, the client determines if a number of non-sequential accesses of a computer-readable medium for the said set of segments from the single-instance-storage volume exceeds a predetermined threshold. If so, the client provides the whole set of data segments for storage within the single-instance storage volume regardless of whether or not the data segments are duplicate data segments. These sent data segments will be stored contiguously within the single-instance storage volume while the duplicates will be removed from their previous stored locations.

摘要： Containers that store data objects that were written to those containers during a particular backup are accessed. Then, a subset of the containers is identified; the containers in the subset have less than a threshold number of data objects associated with the particular backup. Data objects that are in containers in that subset and that are associated with the backup are copied to one or more other containers. Those other containers are subsequently used to restore data objects associated with the backup.

摘要： A method and system for efficient space management for single-instance-storage volumes is provided. A backup module storing data within a collection of containers according to access locality and retention time of the data, wherein the retention time defines an amount of time the data is stored within the collection of containers before deletion of the data, and the access locality comprises an order in which the data is to be accessed is further provided. A compaction module compacting the stored data by selecting at least two containers among the collection of containers, wherein the selection is performed using a predetermined criteria that includes access locality and retention time of the data is also provided. The compaction module distributes the data among the at least two containers. The compaction criteria creates an imbalance among the containers to create more empty, full, or nearly full containers.

摘要： A computer-implemented method for enabling deduplication of attachment files within a database is described. A database file comprising data blocks of an attachment file positioned intermittently among data blocks of the database file is inspected. A first map may be generated from the inspection of the database file and the attachment file. The data blocks of the database file and the data blocks of the attachment file are identified according to the first map. The data blocks of the database file are written to a database data file. The data blocks of the attachment file are written to an attachment data file. The attachment data file is deduplicated with at least one other data file.

摘要： A computer-implemented method for managing data in cloud storage using deduplication techniques is described. At least one unique segment of data is received from at least one backup source. The at least one unique segment of data is written to at least one container file associated with the at least one back up source. An index file is created for the at least one container file. The index file includes information regarding the unique segments of data. A plurality of the unique segments of data is transmitted from the at least one container file as an object to a virtual container on cloud storage. A virtual container is composed of an index file and one or more container files, and the index file and each container file are stored as individual cloud storage objects. Spatial locality of the plurality of unique segments of data is maintained in cloud storage.

摘要： A method for restoring deduplicated data may include receiving a request to restore a set of deduplicated data segments to a client system, where each data segment in the set of deduplicated data segments is referred to by one or more deduplication references. The method may also include procuring reference data that indicates, for each data segment in the set of deduplicated data segments, the number of deduplication references that point to the data segment. The method may further include using the reference data to select one or more data segments from the set of deduplicated data segments for client-side caching, caching the one or more data segments in a cache on the client system, and restoring the one or more data segments from the cache on the client system. Various other methods, systems, and computer-readable media are also disclosed.

摘要： A system and method for caching fingerprints in a client cache is provided. A data object that comprises a set of data segments and describes a backup process is identified. Thereafter, a request referencing the data object is made to a deduplication server to request that a task identifier be added to the data object. If the deduplication server is able to successfully add the task identifier to the data object, then an active identifier is added to each data segment from the set of data segments in a cache that is within a client system.

摘要： A computer-implemented method for creating reference-based synthetic backups. The method may include identifying a first set of references that identify data of a first backup. The first backup may represent at least a portion of a data set at a first time. The method may also include identifying a second set of references that identify data of a second backup. The second backup may represent changes made to the data set between the first time and a second time. The method may further include creating a synthetic backup that represents at least a portion of the data set at the second time by aggregating one or more references from the first set of references and one or more references from the second set of references. Various other methods, systems, and computer-readable media are also disclosed.
