dmzBackup is a program for backing up data in a heterogeneous DMZ network. It features disk-to-disk backup of remote/local host data, data encryption, multiple simultaneous data flows, error logs and email reporting, a search tool for locating files in a backup, a compressed index, host timestamps for incremental backups, human readable journal logs, host based configuration files, command-line arguments for interactive backups, client side compression, and unlimited (remote) backup clients for one backup host.
Backupninja allows you to coordinate system backup by dropping a few simple configuration files into /etc/backup.d/. Most programs you might use for making backups don't have their own configuration file format. Backupninja provides a centralized way to configure and schedule many different backup utilities.
NNNbackup (No-name network backup) is a simple backup system framework for data in an SMB/CIFS networked environment. It can also be used for backing up local data. The primary focus of this system is the simple selection of data to be backed up and the security of said data. It is also very portable because it relies on common Linux tools and its behavior is controlled entirely by a single and simple configuration file.
bak2disc is a disc-based backup script aimed at being easy to use and powerful. Its most notable feature is the way it groups common files and directories together to preserve structure when data is divided into discs. This functionality is a tunable threshold that lets you control the balance between data contiguity and maximum disc usage. In addition, bak2disc also features resume support, which allows you to stop burning between discs and continue later. Burning is done on-the-fly, using growisofs for DVDs and cdrecord for CDs.
rootpretender is a system that enables special file operations such as the creation of block special and character special device nodes and unlimited chown()ing of files for non-root users of Unix systems. It does this by faking special file operations. For example, chown() is not executed, and mknod() creates regular files instead of device nodes. These operations are remembered, so next time a process under rootpretender's control examines an affected file with stat() or a similar system call, the fake information is returned. It uses LD_PRELOAD and includes patches for rsync 2.6.6 and rsync 2.6.9 for use on systems without LD_PRELOAD support. These make it possible to copy file ownership and device nodes even if root access is not available on the target.
