Abstract: The disclosed computer-implemented method for storing data may include (i) identifying a request to backup a set of data according to a storage-as-a-service configuration that stores data into cloud storage, (ii) dividing the set of data to be backed up into chunks of data, (iii) dividing, for each of the chunks of data, a respective chunk into blocks of data, (iv) generating, for each of the chunks of data, at least one block of parity bits for the respective chunk of data based on applying an erasure code to the blocks of data, and (v) splitting, during backing up the chunks of data according to the storage-as-a-service configuration, the respective blocks of data and the generated block of parity bits into heterogeneous storage media targets such that the storage-as-a-service configuration benefits from the heterogeneous storage media targets. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A computer-implemented method for cloud-based data protection storage may include (1) identifying a request to maintain a data protection image for a volume of data, (2) identifying a third-party storage service to use for storing the data protection image, (3) receiving a stream of data to apply to the data protection image, (4) buffering a portion of the stream of data, (5) writing the buffered portion of the stream to the third-party storage service as a single storage object, and (6) associating the single storage object with the buffered portion of the stream in a data map. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A computer-implemented method for deduplicating archive objects may include (1) tagging, using an archiving service, archive objects to indicate data related to the archive objects, (2) assigning an archive object and an additional archive object to be processed by a deduplication engine, (3) determining a degree of overlap between the archive object and the additional archive object based on tags assigned to the archive object and the additional archive object by the archiving service, and (4) adjusting, using the deduplication engine, deduplication between the archive object and the additional archive object using the degree of overlap determined to exist between the archive object and the additional archive object based on the tags assigned by the archiving service. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A computer-implemented method for managing an inline deduplication module is described. Congestion information is collected about a level of congestion on a network that communicates with an inline deduplication module. An instruction is sent to the inline deduplication module to adjust a deduplication rate based at least in part on the congestion information.

Abstract: A computer-implemented method for managing references in deduplicating data systems may include (1) identifying a first instance of a data segment stored within a deduplicating data system that reduces redundant data storage by storing at least two data objects such that each of the two data objects references the first instance of the data segment, (2) identifying an additional data object to be stored by the deduplicating data system that includes the data segment, (3) determining whether a reference limit associated with the first instance of the data segment has been reached, and (4) storing, based at least in part on determining that the reference limit associated with the first instance of the data segment has been reached, a second instance of the data segment within the deduplicating data system. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Various embodiments of a computer system and methods are disclosed. In one embodiment, a computer system includes a backup application coupled to interconnected storage resources. The backup application creates a database of storage resources, wherein each database entry corresponds to one or more storage resources and is associated with one or more user-defined attributes describing the suitability of the associated resources for a backup operation. The backup application creates and stores a configuration of storage resources for a backup operation. Each storage resource is selected based on a value of an associated attribute. The storage resources may include logical unit numbers (LUNs), mount points providing access to LUNs, and hosts having physical access or network access through other hosts to mount points. An attribute specifies that the associated storage resources are either required or preferred for a backup operation. The database and configuration are created at backup application run time.

Abstract: A system and method for allocating system resources is described herein. In one embodiment, the method comprises creating, in a computer system, a resource consumer and assigning the resource consumer one of a set of flavors. The method further includes determining whether the resource consumer is limited to receiving resources from a certain one of a set of resource providers, wherein each of the set of resource providers has one of the set of flavors. The method further includes marking a field to indicate that the resource consumer is limited to receiving resources from the certain one of the set of resource providers, if the resource consumer is limited to receiving resources from the certain one of the set of resource providers. The method further includes allocating a resource to the resource consumer from one of the set of resource providers whose flavor matches the flavor assigned to the resource consumer.
