Backshift is a deduplicating (variable-sized, content-based blocks), compressing (xz or bz2) backup program. Full saves and incrementals are pretty indistinct other than the amount of data transmitted, somewhat like with "rsync --link-dest" but without the huge number of hardlinks. It also de-duplicates large file content at a granularity of about 2 megabytes on average; there tends to be a unique copy of each file with size less than around 2 megabytes on average.
LBackup is a simple backup system aimed at systems administrators who require reliable backups with minimum fuss. It is configured with configuration files, and the backup is started from the command line. It has been tested for over 10 years. Backups can be to local media, or to remote media via one or more networks. The networks may be private LANs, WANs, or sets of untrusted public networks such as the Internet.
Archive2iso takes a directory tree and randomizes the files in the tree to stripe the files across several ISO files that can be archived or burned off to a CD. The ISO files are generated by calling the CDiso.pm module. It reads an array generated by an INCLUDE LIST so the ISO file can be made with mkisofs. The intended use is to stripe files across multiple CD/DVD randomly so if one disc is damaged all the files that were in the same directory will not be lost since files are spread across multiple disks. The actual files themselves are not split; all files remain in their original state.
Autodl2 is a simple to manage and extensible file transfer system that can be configured simply using a configuration file. The system is designed to be lightweight and handle multiple file transfer protocols. Currently only SFTP is supported, though other systems can be added via a plugin system.
PBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 1.0.2 or newer (ie: anything compressed with PBZIP2 can be decompressed with bzip2).
