Abstract: Methods and apparatuses for efficiently migrating deduplicated data are provided. In one example, a data management system includes a data storage volume, a memory including machine executable instructions, and a computer processor. The data storage volume includes data objects and free storage space. The computer processor executes the instructions to perform deduplication of the data objects and determine migration efficiency metrics for groups of the data objects. Determining the migration efficiency metrics includes determining, for each group, a relationship between the free storage space that will result if the group is migrated from the volume and the resources required to migrate the group from the volume.

Abstract: A method, device and non-transitory computer readable medium that manages read access includes organizing a plurality of requests for objects on one or more storage media, such as tapes or spin-down disks, based on at least a deadline for each of the plurality of requests. One of one or more replicas for each of the objects on the one or more storage media is selected based on one or more factors. An initial schedule for read access is generated based at least on the deadline for each of the plurality of requests, the selected one of the replicas for each of the objects, and availability of one or more drives. The initial schedule for read access on the one or more of the drives for each of the plurality of requests for the objects is provided.

Abstract: Technology is described for responding to service level objectives during deduplication. In various embodiments, the technology receives a service level objective (SLO); receives data to be stored at the data storage system; computes an amount of deduplication to apply to the received data responsive to the SLO; deduplicates the data to the computed amount; and stores the deduplicated data. The deduplicated data may be stored in such a manner that the data can be read in a manner that meets the SLO.
