FreeArc combines best 7-zip and RAR features: auto-selected LZMA/PPMD/Multimedia compression, 1gb dictionary, exe/dict/delta data filters, updatable solid archives, SFXes, recovery record, AES+Twofish+Serpent encryption, Linux support and much more...

DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html

Duply is a shell front end for the duplicity backup tool https://duplicity.us . It simplifies the usage by implementing backup job profiles, batch commands and more. Secure backup to non-trusted file spaces made easy.

A simple keylogger written in python. It is primarily designed for backup purposes, but can be used as a stealth keylogger, too. It does not raise any trust issues, since it is a set of [relatively] short python scripts that you can easily examine.

Simplebackup is a cross-platform backup program. It reads a configuration file then builds a compress backup set, finally places the compressed files into another location (a directory, a remote http,ftp,sftp server or even one or more email accounts).

A slightly reduced strength bulk encryption. In exchange for the reduced strength, you get the ability to rsync the encrypted files, so that local changes in the plaintext file will result in (relatively) local changes to the cyphertext file.

partitioning backup recovery and all kind of boot loaders

Hardware-ID is a small Linux module providing a program by program assignment of certain hardware specific values. Useful for preparing master hard drives, hardware independend backup/restore and some exotic hardware.

Backup P2P is a peer to peer application doing automated and secured backups inside a community (Jabber, XMPP). Each user shares some available space on his disk with others, to be able in return to remotely backup some of his own data.

Rsync friendly encryption that runs on the UNIX command line. Encrypt a file and backup the changes to an untrusted host.

Robbie is a cross-platform framework for backing up data on computers. It uses secure hashes to keep track of files, and when you alter them it sends the new version to your backup store - either locally or remotely.

SFXCompress is an utility used to pack and/or encrypt a directory on a self-extracting file. It also includes the calculation of the MD5 function to check if the compressed file is correct. SFXCompress-gui is the graphical user interface written in Java of the Console utility sfxcompress. The Application comes also with the console version. MAC users, download "SFXCompress-bundle.dmg", double click and execute the script "InstallationScript" included into the dmg image. Linux Users: download "sfxcompress-bundle.tar.gz" or "sfxcompress-bundle.tar" and execute the script "install".

dumpnet is a collection of bash scripts that allows you to backup multiple servers simultaneously. You can do incremental file system dumps with tar, dump and rsync, backup databases and much more. AIDE can also easily be integrated.

It is a small java eclipse plugin. This software makes workspace backups and restores them. You can use this plugin as workspace switcher too.
