Afio makes cpio-format archives. It deals somewhat gracefully with input data corruption, supports multi-volume archives during interactive operation, and can make compressed archives that are much safer than compressed tar or cpio archives. Afio is best used as an `archive engine' in a backup script.
The BRU Backup and Restore Utility features data-verified backups, scalability, configurability, and ease of use for Linux and Unix. Versions are available for Linux, FreeBSD, and most UNIX variants. It works via an X11 interface, command line interactive, or through a scripted, scheduled (CRON) mechanism.
The dump package contains both dump and restore. Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.
e4Graph is a C++ library that allows programs to store graph-like data persistently and to access and manipulate that data efficiently. With e4Graph, you can arrange your data in the most natural form that reflects the relationships between its parts, rather than having to force it into a table-like format. The e4Graph library also allows you to concentrate on the relationships you want to represent, and not on how to store them in a database. You can modify data items, and add and remove connections and relationships between pieces of data on the fly. e4Graph allows you to represent an unlimited number of different connections between pieces of data, and your program can selectively manipulate the data according to the relationships it cares about, not having to know about other connections represented in the data set.
epkg is a package manager which uses the Encap Package Management System, a method for flexibly handling installation and management of third-party software on a Unix system. Encap places each package in its own subdirectory, then automatically manages symlinks to their appropriate places in /usr/local. The Encap package format includes features like postinstall scripts and prerequisite checking. Other features include builtin tar/gzip extraction, optional builtin FTP and HTTP support, transaction logging, and the ability to automatically upgrade a package to the latest version.
