A system and method for efficient transfer of data over a network. A data source and a destination are coupled to one another via a network. The data source is configured to transmit data to the destination and determine a network latency associated with the transmission. In response to determining a first transmission parameter may not be optimized, the source is configured to modify the first transmission parameter and evaluate its effect on data throughput. The source may repeat such modifications as long as throughput is increased. Once the first transmission parameter is deemed optimized, the source may perform a similar procedure for a second transmission parameter. In various embodiments, the first transmission parameter may correspond to a packet size and the second transmission parameter may correspond to a number of streams being processed by the source.

System and method for optimizing transportation over networks

A method for managing deduplication reference data may include (1) identifying multiple of data containers configured to store a plurality of deduplicated data segments that are referenced by multiple data objects within a deduplicated data system, (2) maintaining multiple reference databases including (i) a first reference database corresponding to a first subset of the data containers and (ii) a second reference database corresponding to a second subset of the data containers, the second subset differing from the first subset, (3) determining that a data object references at least one segment within a first data container within the first subset but does not reference any data segment within a second data container within the second subset and (4) updating the first reference database with information specifying that the data object references at least one data segment within at least one data container within the first subset of data containers.
