scdbackup is a simplified CD/DVD backup program for Linux. It can back up large amounts of data on one or more media, with no special tools needed for reading the backup. It supports ISO9660 filesystems and afio archives. Its special features are automatic division of data into multiple volumes, verification of write success, incremental backups, a search and restore helper for large ISO9660 backups. CDs get written via cdrecord, wodim, cdrskin, or xorriso. DVDs and BDs get written via growisofs, cdrskin, or xorriso.
SnapSource is a utility written in Perl to automatically and periodically take a snapshot (incremental backup) of your source code and display the modifications in a 2-column (original and modified) format similar to that of cervisia. Changes, additions, and deletions are displayed in different colors, customizable per user preference. It is not another CVS, and it is not a front-end to CVS, but it is supposed to be used in between CVS commits.
Star is a very fast, POSIX-compliant tar archiver, maintained for more than 30 years. It saves many files together into a single tape or disk archive, and can restore individual files from the archive. It includes command line interfaces for the "tar", "Sun-Tar", "cpio", "pax", and "gnutar" command-line syntax. It includes a FIFO for speed, a pattern matcher, multi-volume support, the ability to archive sparse files and ACLs, the ability to archive extended file flags, automatic archive format detection, automatic byte order recognition, automatic archive compression/decompression, remote archives, and special features that allow star to be used for full and incremental backups. It includes the only known platform independent "rmt" server program.
Taper is a tape backup and restore program that provides a friendly user interface to allow backing/restoring files to a tape drive. Alternatively, files can be backed up to hard disk files. Selecting files for backup and restore is very similar to the Midnight Commander interface and allows easy traversal of directories. Recursively selected directories are supported. Incremental backup and automatic most recent restore are defaults settings. SCSI, ftape, zftape, and removable drives are supported.
SystemImager automates the installation of Linux to masses of similar machines. Software distribution, configuration, and operating system updates are made easy, including updates from one Linux release to another. It can also be used for content distribution on Web servers. It is most useful in environments with large numbers of identical machines. Some typical environments include Internet server farms, high performance clusters, computer labs, and corporate desktop environments where all workstations have the same basic hardware configuration.
Xfiles is an interactive utility for comparing and merging one file tree with another over a network. It supports freeform work on several machines (no need to keep track of what files are changed on which machine). Xfiles can also be used as a cross-validating disk<->disk backup strategy.
