AllWorldIT DBackup is a backup system which creates one archive per directory it backs up. This makes searching through the backup much easier, as you can look for which files you're after in the directory hierarchy. It will only back up directories which have changed, which makes it rsync friendly.
BakAndImgCD is a small Linux-based operating system which has been designed to perform the two tasks: data backup (with support for btrfs, ext2, ext3, ext4, FAT, HFS, HFS+, jfs, Minix, NTFS, ReiserFS, and XFS) and disk imaging (using Partimage, Partclone, and GNU ddrescue). The output files (archives and images) can be optionally compressed and sent to a remote FTP sever via Ethernet, WiFi, or dial-up. It is fully compatible with UNetbootin, which can be used to create an easy-to-use live USB.
Redo Backup and Recovery is an extremely easy point-and-click rescue live CD with a suite of tools for system backup and recovery, partition editing, deleted file recovery, drive management, data protection, and more. The backup tool stores an image of the entire hard drive, so recovery from viruses, malware, or disc failures takes minutes. It boots from a CD or USB drive. It automatically locates local drives, USB drives, and network-shared drives to make backup storage and retrieval as simple as possible for anyone. The menu-driven GUI includes a Web browser for downloading drivers and a terminal with advanced command line tools.
XCloner is an application to backup and restore component designed for PHP/MySQL Web sites. It can work as a native plugin for WordPress and Joomla! or as a standalone application. XCloner was designed specifically to generate custom backups of any LAMP Web site through custom admin inputs. It can restore backups to any other location with the help of the automatic restore script, independent from the main package. XCloner uses standard formats like tar and MySQL, allowing backups to be restored in a variety of ways.
Libchop is a set of utilities and library for data backup and distributed storage. Its main application is chop-backup, an encrypted backup program that supports data integrity checks, versioning at little cost, distribution among several sites, selective sharing of stored data, adaptive compression, and more. The library itself, which chop-backup builds upon, implements storage techniques such as content-based addressing, content hash keys, Merkle trees, similarity detection, and lossless compression. It makes it easy to combine them in different ways. The ‘chop-archiver’ and ‘chop-block-server’ tools, illustrated in the manual, provide direct access to these facilities from the command line. It is written in C and has Guile (Scheme) bindings.
luckyBackup is a powerful, fast, reliable, and fully customizable backup and sync tool. It can backup any directory (the source) to another (the destination). luckyBackup copies over only the changes you've made to the source directory and nothing more, saving a great deal of time for backups after the first one. Whatever changes you make to the source, including adding, moving, deleting, modifying files or directories, will have the same effect on the destination. Owner, group, time stamps, links, and permissions of files are preserved (unless directed otherwise). The synchronization feature works on any pair of directories, keeping the files that were most recently modified on both of them. It includes many safety checks to prevent accidental loss of data.
