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.
W-Packager is a packager similar to dpkg that can be used by anyone to create and maintain Debian packages under Linux or other Unix systems. The aim of the project is primarily to have a workable version of a packager that can be compiled on many systems, including those that do not support fork(). At this time, W-Packager is used within UniGW. It can also be used under Linux.
G4L is a hard disk and partition imaging and cloning tool. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the "Click'n'Clone" function. G4L supports file splitting if the local filesystem does not support writing files larger than 2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.
BitRock InstallBuilder allows you to create easy-to-use multiplatform installers for Linux (x86/PPC/s390/x86_64/Itanium), Windows, Mac OS X, FreeBSD, OpenBSD, Solaris (x86/Sparc), IRIX, AIX, and HP-UX applications. The generated application installers have a native look-and-feel and no external dependencies, and can be run in GUI, text, and unattended modes. In addition to self-contained installers, the installation tool is also able to generate standalone RPM packages.
Freedup finds and eliminates duplicate files by linking them, and thus reduces the amount of used disk space within one or more file systems. By default, hardlinks are used on a single device, symbolic links when the devices differ. A set of options allows you to modify the methods of file comparison, the hash functions, the linking behavior, and the reporting style. You may use batch or interactive mode. Freedup usually only considers identical files, but when comparing audio or graphics files, you may elect to ignore the tags.
sdd is a replacement for a program called 'dd'. sdd is much faster than dd in cases where input block size (ibs) is not equal to the output block size (obs). Statistics are more easily understood than those from 'dd'. Timing available, -time option will print transfer speed Timing & Statistics available at any time with SIGQUIT (^\) Can seek on input and output Fast null input Fast null output. Support for the RMT (Remote Tape Server) protocol makes remote I/O fast and easy.
Rsyncrypto allows you to encrypt a file or a directory structure such that they can later be synchronized to another machine using rsync. This means that local changes to the plain text file result in local changes to the cipher text file. rsyncrypto compresses the plain text file prior to encrypting it with gzip using the "rsyncable" patch, which is available from the rsync sources.
Unison is a file-synchronization tool for Unix and Windows. It allows two copies of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other. Unison can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are propagated automatically. Conflicting updates are detected and displayed. Unison can communicate through a direct socket link or through an rsh/ssh tunnel. It uses network bandwidth efficiently.
NEPM monitors and reports uptime, critical events and their predecessors, access rates, bytes-served rates, and error rates for network node equipment. Hardware and software elements within the nodes are tracked and reported separately to make possible rapid fault isolation. It is a very general, highly configurable, two-part software system that captures and analyzes logged performance data from IP-networked equipment and reports it via email and Web pages. Current conditions and history from systems based on Windows NT/2000, Unix, and Unix-style operating systems can be tracked and reported. Most major server, switch and router systems can be monitored, without running agents on the target systems. NEPM itself is system-independent and can be hosted on either a Unix or Win NT system or a combination of these with equal ease.
