Abstract
The system includes a plurality of storage volumes, a data synchronization module, a space-efficient storage module, and a heat data module. A second storage volume of the plurality of storage volumes includes a backup storage location for a first storage volume. The data synchronization module, coupled to the first storage volume and the second storage volume, provides a backup by synchronizing information from the first storage volume to the second storage volume during a synchronization event. The information includes data chunks, heat map data, and first metadata. The space-efficient storage module receives the information from the data synchronization module and allocates the information to the second storage volume in accordance with a space-efficient storage model. The heat data module reads the first metadata and the heat map data and adjusts a location of the data chunks in the second storage volume based on the heat map data.
