A method and apparatus for directly connecting very large data streams from an archive command into a backup data system using an "intelligent process." An output stream is piped into an intelligent pipe-reading process and distributed over a set of temporary data stores built from raw storage resources. A pipe interface process supervises backup of each filled data store, while the remaining output stream continues to be piped into another available data store. The backup system completes archiving of the datastream, keeping a catalog of the datastream storage locations. To retrieve the data, the intelligent process is run in reverse as a pipe-writing process, requesting data from the backup system. Retrieved data traverses the data stores from the backup system and are pumped into the pipe-writing process for delivery to the pipe output file identified by the retrieve or import command.
