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.
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.
ISO Master is an easy to use GUI CD image editor for Linux, BSD, and Windows. Basically, you can use this program to extract files from an ISO, add files to an ISO, and create bootable ISOs, all in a graphical user interface. It can open both ISO and NRG files, but can only save as ISO. It is based on bkisofs, a library for reading, modifying, and writing ISO images.
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.
K9Copy facilitates several methods for backing up a DVD. The software enables direct backup of a single layer DVD-5, provided the user's computer has a DVD recorder. Likewise, direct backup of a dual layer DVD-9 is possible with a dual layer DVD recorder. K9Copy is also able to fit the contents of a dual layer DVD-9 onto a single layer DVD-5. The interface allows a user to explicitly retain or discard any content from the original disc such as video titles, audio tracks, subtitles, and the DVD menu. All content selected for backup is compressed to a configurable target size (4400 MB by default) and stored on the user's hard drive as either an ISO image file or a DVD VIDEO_TS folder. K9Copy can either transfer the backup data to blank DVD±R media or utilize external DVD authoring software such as K3b for this task. Furthermore, an ISO image file produced by K9Copy can be recorded to DVD by any software on any platform capable of recording ISO images to disc. It can also back up a DVD to a video file (such as MPEG-4).
