The BRU Backup and Restore Utility features data-verified backups, scalability, configurability, and ease of use for Linux and Unix. Versions are available for Linux, FreeBSD, and most UNIX variants. It works via an X11 interface, command line interactive, or through a scripted, scheduled (CRON) mechanism.
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.
GNU EPrints is a solution for sites wanting to set up archives. By default it is configured to be an archive of research publications but can be easily altered. It is scalable and robust; all metadata is stored in UTF-8 rather than ASCII, and all "phrases" the system uses in user interaction are stored in an XML file for easy editing or translating. The system is built around Apache, mod_perl, and MySQL. Submissions are made via the Web and not entered into the main archive until approved by an editor.
Installwatch is a simple utility which keeps track of which files are created and modified during the installation of a new program. It's fast and easy to use. It doesn't require a "pre-install" phase because it monitors processes while they run. Installwatch works with every dynamically linked ELF program, by intercepting system calls that cause file system alterations.
KBACKUP is intended for handling of backups no matter whether they reside on disk or tape or even in files. As most other backup programs available today are either confusing the user with lots of long command line options, or user friendly but not powerful at all, the aim behind writing KBACKUP was to provide a user friendly yet powerful backup program. It is also intended to be kept compatible to existing and well proven archive formats, so you can restore your archives even if you should not have KBACKUP around anymore.
MAT is an easy-to-use network-enabled UNIX configuration and monitoring tool. It provides an integrated tool for many common system administration tasks, including backups, replication, and running commands on hundreds of machines at once. It includes a warning system for potential system problems, and graphing of many common system parameters. MAT provides many of the tools a system administrator needs during the day, including DNS, NIS, Backups, and Replication. One can run a MAT command on many hosts at once. A simple editor window is provided which can modify a set of machine's configurations in one session.
