说明
rzip is a compression program designed for large files. It operates in two stages: first, it finds and encodes large chunks of duplicated data over potentially very long distances (up to nearly a gigabyte) using a rolling-checksum algorithm similar to rsync. Second, it uses bzip2 to compress the output of the first stage. The long-range matching makes rzip particularly effective on files with repeated content spread far apart, which standard compressors cannot exploit.
