Abstract: A request for allocating a storage unit of a storage system is received to back up data of one or more clients. 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.
