Abstract
Techniques and mechanisms described herein facilitate the transmission of a data stream from a client device to a networked storage system. According to various embodiments, a fingerprint for a data chunk may be identified by applying a hash function to the data chunk via a processor. The data chunk may be determined by parsing a data stream at the client device. A determination may be made as to whether the data chunk is stored in a chunk file repository at the client device. A block map update request message including information for updating a block map may be transmitted to a networked storage system via a network. The block map may identify a designated memory location at which the chunk is stored at the networked storage system.
