Abstract

A system and method are provided for storing and using recovery state information during a data stream transfer, such as a download. During the download of compressed, archived data, the system tracks the position of the last file boundary and the position of the last compression block boundary before the last file boundary, and the system stores this information as a recovery state. If the download is interrupted, the system uses the recovery state information to resume the download at an efficient location in the data stream.
