Abstract
An illustrative method for storing disaster recovery data includes receiving a plurality of copies of data stored by a first memory device. Each of the plurality of copies includes a plurality of blocks of data. The method also includes storing, in a second memory device, the plurality of copies in an object-oriented format, determining, using recovery time objectives, a number of the plurality of copies to be stored in a block-oriented format, and selecting a subset of the plurality of copies having the determined number of the plurality of copies. The method further includes assigning each of the other copies of the plurality of copies to one of a plurality of clusters. Each cluster of the plurality of clusters includes one of the subset of the plurality of copies. The method also includes determining, for each cluster, a copy having a highest number of blocks also present in the other copies of the cluster and storing, in the block-oriented format, the determined copy from each cluster in a third memory device.
