Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A method comprising: maintaining, by a data storage system, a data storage volume that includes a plurality of data objects and free storage space, wherein a deduplication operation has been performed on the data storage volume; and computing, by the data storage system, a migration efficiency metric for each of a plurality of subsets of the data objects, wherein each migration efficiency metric is based on a relationship between an increase in an amount o…
