Abstract: Methods, systems, and computer program products for multi-cloud shared data management. A first storage facility on a first cloud is established and a second storage facility on a second cloud established. The first cloud and the second cloud comprise at least respective first deduplication metadata and second deduplication metadata. In response to receipt of a request to store a content object comprising at least one candidate deduplication chunk, an inter-cloud deduplication protocol is initiated. The inter-cloud deduplication protocol determines whether or not a candidate deduplication chunk of a data item is already stored at either the first cloud or the second cloud. In the event that the candidate deduplication chunk of the data item deemed to have been already stored then, rather than storing a further copy of the bit sequence corresponding to the candidate deduplication chunk, instead, merely referring to the location of the already stored candidate deduplication chunk.

Abstract: An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions to receive, from a client, a request to create a catalog item corresponding to a file, determine an identifier of a cluster manager associated with a cluster having available capacity, send, to the cluster manager, a source location of the catalog item, and cause the cluster manager to store the catalog item from the source location in the cluster.
