OzVM (Virtual Machine Project) is a simple, lightweight, secure virtual machine. The current target application of OzVM is OzStream, which allows platform independent self-decoding of data. The vision of OzStream is to make any and all compressed media self-extracting. OzStream abstracts compressed media from client applications, providing new freedom for users, developers, and compression techniques.
Better Backup is a backup manager designed to handle large volumes of data at high speed. It is extremely fast and flexible. The system is designed to back up to magnetic tape, CD/R, or DVD-R, or almost any other media. One of the main features of this program is its ability to preform a fast restore from magnetic tape through its use of file markers. The program is extremely flexible allowing the user to customize most aspects of the backup through a configuration file.
Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, DVD, CD, ZIP, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links, extended attributes, file forks, Door inodes, and sparse files, remote backup using pipes and external commands (such as ssh), and rearrangement of the "slices" of an existing archive. It can run commands between slices, before and after saving some defined files or directories (for a proper database backup, for example), and quickly retrieve individual files from differential and full backups. Several external GUIs exist as alternatives to its CLI interface, like kdar, DarGUI, SaraB, etc.
Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip decompresses almost as fast as gzip and compresses more than bzip2, which makes it well suited for software distribution and data archiving. Lzip is a clean implementation of the LZMA algorithm. The Lzip file format is designed for long-term data archiving. It is clean, provides very safe four factor integrity checking, and is backed by the recovery capabilities of lziprecover.
Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz) able to repair slightly damaged files, recover badly damaged files from two or more copies, extract data from damaged files, decompress files, and test integrity of files. Lziprecover is able to recover or decompress files produced by any of the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip, and pdlzip. It makes lzip files resistant to bit-flip, one of the most common forms of data corruption, and its recovery capabilities contribute to make of the lzip format one of the best options for long-term data archiving.
Bacula is a set of programs that allow you to manage the backup, recovery, and verification of computer data across a network of different computers. It is based on a client/server architecture and is efficient and relatively easy to use, while offering many advanced storage management features that make it easy to find and recover lost or damaged files.
