bpkg is a utility that tries to simplify the process of trying out new programs from source. For most packages, this can be as simple as "bpkg <url or tarball>". bpkg will download, extract, configure, compile, install, generate a package in your system's native format, and finally integrate that package into your system's packaging system so that you can remove it cleanly. It has auto-detection for Arch Linux, Slackware, Red Hat, Gentoo, and SuSE (though not all packaging back-ends are complete). bpkg is not intended as a replacement for normal packaging utilities.
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.
