An integrated approach for duplication of data in a distributed environment that includes a source and a destination

One aspect of the present invention comprises a configuration of a storage management system, the conducting Deduplizierungsaktivitaten both at the client (source) - and allows the server (target) site. The location of the deduplication can then be optimized based on system conditions or pre-defined policies. In one embodiment, a seamless switching of Deduplizierungsaktivitaten between the client and the server is made possible by use of uniform Deduplizierungsprozessalgorithmen and access to the same deduplication (including information about the hashed Datenchunks). In addition, any data transformations of the chunks are performed after identification of the Datenchunks. Accordingly, the memory system using this memory configuration suitable Chunks generated using either the client or server side deduplication, find and use.
