A storage system according to certain embodiments includes a client-side signature repository that includes information representative of a set of data blocks stored in primary storage. During copy or backup operations, the system can use the client-side signature repository to identify data blocks located in primary storage that are new or that have changed. The system can also use the client-side signature repository to identify multiple locations within primary storage where different instances of the data blocks are located. Accordingly, during a copy or backup operation of one client computing device, the system can source a data block that is to be copied to secondary storage from another client computing device that includes a second instance of the data block. |
