httplog is a replacement for Apache's 'rotatelogs' and Andrew Ford's 'chronolog'. It allows you to specify a logfile using strftime paramaters in the filename to act as a template. This means that the logs in your logfiles will also be sorted according to the filename. For example, if you specify a logfile of /var/log/http%Y%m%d.log, a new log file would be generated each day, with content for only that one day. It also supports compression of logfiles using gzip, and many other useful functions.

The gzip Recovery Toolkit attempts to automate the recovery of data from corrupted gzip files (including tarballs) through a program called gzrecover. This package is still very experimental at this point.

xz is a data compression program using the LZMA algorithm and a similar user interface to gzip. Typically it compresses both tighter and faster than bzip2, and decompresses nearly as fast as gzip. The .xz file format includes headers and checksums, and also includes data filters (LZMA2) that can increase compression further.

archivemail is a tool written in Python for archiving and compressing old email in mailboxes. It can move messages older than the specified number of days to a separate mbox-format mailbox that is compressed with gzip, or optionally just delete old email. It supports archiving IMAP, mbox, MH, and maildir format mailboxes.

rzip is a compression program for large and very large files. It uses an effective history buffer of 900 MB which allows it to spot redundancy over very long distances. It is usually faster than bzip2 and usually produces smaller files.

pngquant is a batch conversion utility to quantize and dither truecolor PNG images, especially those with a full alpha channel, down to "RGBA-palette" PNGs (i.e., PLTE + tRNS in PNG parlance). Such images are usually two to four times smaller than the full 32-bit versions, and partial transparency is preserved quite nicely. This makes pngquant especially useful both for Web sites and for PlayStation 2 development, where one of the texture formats is RGBA-palette-based (though not PNG-compressed).

lzop is a file compressor similar to gzip. Its main advantages over gzip are much higher compression and decompression speed at the cost of some compression ratio. lzop uses the LZO library for compression services.

Infobright Community Edition (ICE) is an analytic database built on MySQL, designed to deliver very fast query response against large data volumes. It is a self-tuning, columnar database that eliminates the need to create or maintain indexes, partition data, or perform other administrative tasks.

Cromfs is a compressed read-only filesystem for Linux. Cromfs is best at archiving gigabytes of big files that have a lot of redundancy. It aims primarily at achieving a strong compression, even at the cost of memory and CPU time resources. It uses the LZMA compression algorithm from 7-zip and block merging.
