- Try compact, posted 1 or 2 Year's ago in comp.sources.*.

- DESCRIPTION
- compact is a modified Lempel-Ziv-Welsh data compression
- utility designed to do high speed data
- compression/decompression of large files, particularly
- system backups. The algorithm resembles the V.42bis
- compression engine, but was developed independently.
-
- This program is similar to the well known compress program
- but runs faster, compresses large files better, and has a
- superior worst case expansion of incompressable data. The
- program supports multi-volume data sets, and can run as
- multiple concurrent tasks to overlap compute and I/O
- activities. These characteristics make it particularly
- useful when doing periodic system backups, especially with
- streaming tape drives.
