libarxx is a C++ archiver with advanced features, like data synchronization and merging of multiple archives. It provides an object-oriented view on a directory tree of data items and allows versioning, compressing and structuring in multiple ways.
OpenDark is a free simplification of 'dark'. It's the first open BWT-DC compressor, which has a simple code, high speed and compression ratio. And it's waiting for your ideas! :)
Simple light-weight file compression and decompression utilities. Written in C and portable to all platforms. Simple compress and decompress subroutines can be linked and called within applications to compact or unpack data on the fly or stand-alone.
Alternative approach to minimum redundancy coding (fixed-length) without using tree data structures. The main advantages are simplicity and flexibility.
KGB Archiver is the compression tool with unbelievable high compression rate. It surpasses even such efficient compression tool like 7zip and UHARC in terms of the abilities. KGB Archiver uses AES-256 encryption to encrypt archives.
UPX with Autoupdate Capability allows the user to pack Firefox and Thunderbird binaries with UPX and use autoupdate without having to backup the original files. This is useful for Firefox and Thunderbird Portable on flash drives with limited capacity.
A patent-free audio codec designed especially for voice (unlike Vorbis which targets general audio) signals and providing good narrowband and wideband quality. This project is complementary to the Ogg Vorbis codec.
Simple command-line directory incremental backup tool. Create compressed point-in-time snapshots, adding only new or modified files each time. Uses a file catalog so previous zip volumes are not needed for backup. Archives are automatically time-stamped.
Compresses music from 1/50th to 1/100th its original size by removing dissonant parts of sound and also optimizes it for lower speaker-stress, dynamic equalization (2-3 times less hearing stress at high volume), non-compression modes and much more.
Shoelacer generates C code to compress short strings based upon provided sample data. The resulting routines use small models with low memory overhead.
czip is a unix based utility written for the cell broadband engine. It allows its users to compress files in gzip format. It uses Jean-loup Gailly's deflate algorithm and is based in part on pigz, Mark Adlers parallel version of zlib.
A pure Java zip compression library for Java ME CLDC/MIDP applications. It is mostly compatible with java.util.zip in Java SE/CDC, so that an application can easily handle a zip file in the same manner as that in Java SE/CDC.
Lossless compression program with various algorithms included. Intended for large XML files, but can compress any files. Best results with block compression (BWT+MTF+RLE) on large block over alphabet of words.
GD RCS is a revision contol system which supports repository on removable media. It combines the abilities of PRCS, archiving tools like Zip and backup utilities.
NuFX or "ShrinkIt" archives are the de-facto standard in the Apple II (and A2 emulator) world. NufxLib is a full-featured library of functions that manipulate NuFX archives (.SHK, .SDK, .BXY). NuLib2 is a command-line utility built on top of NufxLib.

Simplebackup is a cross-platform backup program. It reads a configuration file then builds a compress backup set, finally places the compressed files into another location (a directory, a remote http,ftp,sftp server or even one or more email accounts).
this is simple backup client<=>server oriented system;
you put the server on the machine you want to backup;
and the client on the machine used for storage;
