Abstract
A set of data chunks stored in a first data storage system is accessed. The set of data chunks includes original data chunks and replicated data chunks respectively corresponding to the original data chunks. A given original data chunk and the corresponding replicated data chunk are stored in separate storage nodes of the first data storage system. For each of at least a subset of storage nodes of the first data storage system, unique ones of the original data chunks and the replicated data chunks stored on the storage node are aggregated to form a data object. The data objects thereby formed collectively represent a given data volume. Each of the data objects is stored in separate storage nodes of a second data storage system.
