Abstract
Format identification for fragmented data is disclosed. In some embodiments, an input stream of information that is divided into fragments is received. Fragment boundaries are determined and a data format for each fragment is found based on continuity properties including by: dividing the stream of information into windows, determining whether each window has a known or unknown format; and comparing portions of windows having an unknown format with neighboring windows to determine fragment boundaries. The stream of information is compressed using a compression technique selected based on the data format, and the compressed stream is stored.
