Combining data streams in storage network
WO 2005050383 A3
Abstract
Described herein are systems and methods for multiplexing pipelined data for backup operations. Various data streams are combined such as by multiplexing by a multiplexing module (140). The multiplexing module (140) combines the data from the various data streams received by receiver module(s) (135) into a single stream of chunks. The multiplexing module (140) may combine data from multiple archive files into a single chunk. Additional modules (145) perform other operations on the chunks of data to be transported such as encryption, compression, etc. The data chunks are transmitted via a transport channel (155) to a receive pipeline that includes a second receiver module (165) and other modules (170). The data chunks are then stored in a backup medium. The chunks are later retrieved and separated such as by demultiplexing for restoring to a client or for further storage as auxiliary copies of the separated data streams or archive files.
