Duplicati is a backup system and an implementation of Duplicity. Duplicati enables you to set up and monitor backups on Windows or Linux. Duplicati is based on the Linux-only Duplicity backup system. Duplicati has a very user friendly interface that allows you to configure and monitor your backups. It supports backing up to a variety of destinations, such as a network folder, a USB disk, a remote FTP server, a remote SSH server, Amazon S3 storage, or a WebDAV enabled server. All backups can be encrypted and are digtally signed, so that no other person can read or tamper with the backed up data.
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.
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).
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.
backstep.py is a backup program that can be run in a directory. It makes a snapshot backup of the directory in a specified interval. The system backs up every file that has changed or was created in the specified interval. The user can restore a backup by telling the system to restore a backup that is a given amount of time old.
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.
