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.
