The storage system includes multiple storage units and each storage unit storing data that is deduplicated within each storage unit. In response to the request, one or more of the storage units are selected based on an amount of deduplicated data that would be stored in each of the storage units after storing the data of the one or more clients. The selected one or more storage units are allocated to the one or more clients to back up the data of the one or more clients.

摘要： A method of determining whether a data segment is a duplicate using cooperating deduplicators is disclosed. The data segment is received. A first deduplicator is operated to to determine whether the incoming data segment is a duplicate based on first information available to the first deduplicator regarding stored data segments that are stored in a memory. A second deduplicator is selectively operated to determine whether the incoming data segment is a duplicate based on second information available to the second deduplicator; wherein the selective operation of the second deduplicator depends on the determination made by the first deduplicator.
