Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, DVD, CD, ZIP, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links, extended attributes, file forks, Door inodes, and sparse files, remote backup using pipes and external commands (such as ssh), and rearrangement of the "slices" of an existing archive. It can run commands between slices, before and after saving some defined files or directories (for a proper database backup, for example), and quickly retrieve individual files from differential and full backups. Several external GUIs exist as alternatives to its CLI interface, like kdar, DarGUI, SaraB, etc.
Unibas is a program (a "fat client" of PostgreSQL) to manage frequently used entity types. Its mission is to create a relational database that is both human- and machine-readable (semantic) to collect data about people, documents (books, songs, movies, etc.), products (CDs, DVDs, etc.), fictional characters, events, places and other entities for personal and collective use. It features complete archive management. You get a document (text, image, music, video) from somewhere (e.g. from the Internet) and tell Unibas to take care of it. Unibas does the rest. Album management: CDs can be lost or destroyed by scratches or heat. Unibas makes it easy to back them up, including most of the metadata (composers, artists, titles, etc.). Organize your knowledge in a tree structure like most modern scientific books, yet extended over the complete human knowledge. Link your knowledge with existing knowledge in the tree and with external documents. Tap the many human-readable sources on the Internet and put their content in an ordered, machine-readable, semantic form. Explain words in a dictionary through well understood language-agnostic notions.
The ATA over Ethernet Tools are intended for use in conjunction with an ATA over Ethernet (AoE) driver for a Linux 2.6 kernel, called "aoe". The tools perform simple tasks like listing available devices, triggering device discovery, and restricting the network interfaces on which AoE is performed.
SILVERCODERS DocToText is a powerful utility which can convert documents in many formats to plain text. It includes a console application and C/C++ library, which allows embedding text extraction mechanisms into other applications. It supports MS Office binary formats (MS Word (DOC), MS Excel (XLS), MS PowerPoint (PPT), and Rich Text Format (RTF)), OpenDocument formats (text documents (ODT), spreadsheets (ODS), and presentations (ODP)), Office Open XML formats (MS Word (DOCX), MS Excel (XLSX), and MS PowerPoint (PPTX)), and HyperText Markup Language (HTML). DocToText can extract text not only from the document body but also from annotations (comments) embedded in odt, doc, docx, or rtf files and read metadata like author, last modification date, or number of pages. It can be used as a fast console viewer, and is able to convert corrupted OpenDocument and Office Open XML documents. It can be used to recover text even if other recovery methods failed.
Back In Time is a simple backup tool for Linux (Gnome & KDE4) inspired by the "flyback project" and "TimeVault". The backup is done by taking snapshots of a specified set of directories. All you have to do is configure: where to save snapshot, what directories to backup, and when a backup should be done (manually, every hour, every day, every week, or every month). It acts as a "user mode" backup system. This means that you can backup and restore only folders to which you have write access.
fsarchiver is a system tool that allows you to save the contents of a filesystem to a compressed archive file. The filesystem can be restored on a partition that has a different size, and it can be restored on a different filesystem. Unlike tar/dar, fsarchiver also creates the filesystem when it extracts the data to partitions. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just lose the current file, not the whole archive.
