rsnapshot is a file system snapshot utility based on rsync. rsnapshot makes it easy to make periodic snapshots of local machines, and remote machines over SSH. To reduce the disk space required for each backup, rsnapshot uses hard links to deduplicate identical files.

Rdiff-backup backs up one directory to another, possibly over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. Rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership, modification times, extended attributes, acls, and resource forks. Also, rdiff-backup can operate in a bandwidth efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up to a remote location, and only the differences will be transmitted. Finally, rdiff-backup is easy to use and settings have sensible defaults.

Borg is a deduplicating backup program. Optionally, it supports compression and authenticated encryption. The main goal of Borg is to provide an efficient and secure way to backup data. The data deduplication technique used makes Borg suitable for daily backups since only changes are stored. The authenticated encryption technique makes it suitable for storing backups on untrusted computers.

Grsync is a simple graphical interface using GTK for the rsync command line program. It currently supports only a limited set of the most important rsync features, but can be used effectively for local directory synchronization.

borgmatic is simple, configuration-driven backup software for servers and workstations. Protect your files with client-side encryption. Backup your databases too. Monitor it all with integrated third-party services. borgmatic is powered by borg.

Sed is a non-interactive, text stream editor. It receives a text input from a file or from standard input and it then applies a series of text editing commands to the stream and prints its output to standard output. It is often used for substituting text patterns in a stream. The GNU implementation offers several extensions over the standard utility.

This package provides all the locales supported by the GNU C Library, more than 400 in total. To use them set the LOCPATH environment variable to the share/locale sub-directory of this package.

This package provides a small sample of UTF-8 locales mostly useful in test environments.

Patch is a program that applies changes to files based on differences laid out as by the program "diff". The changes may be applied to one or more files depending on the contents of the diff file. It accepts several different diff formats. It may also be used to revert previously applied differences.

Any Unix-like operating system needs a C library: the library which defines the "system calls" and other basic facilities such as open, malloc, printf, exit...

The GNU C library is used as the C library in the GNU system and most systems with the Linux kernel.

The Time Zone Database (often called tz or zoneinfo) contains code and data that represent the history of local time for many representative locations around the globe. It is updated periodically to reflect changes made by political bodies to time zone boundaries, UTC offsets, and daylight-saving rules.

GNU Binutils is a collection of tools for working with binary files. Perhaps the most notable are "ld", a linker, and "as", an assembler. Other tools include programs to display binary profiling information, list the strings in a binary file, and utilities for working with archives. The "bfd" library for working with executable and object formats is also included.

Tar provides the ability to create tar archives, as well as the ability to extract, update or list files in an existing archive. It is useful for combining many files into one larger file, while maintaining directory structure and file information such as permissions and creation/modification dates. GNU tar offers many extensions over the standard utility.

GNU Coreutils package includes all of the basic command-line tools that are expected in a POSIX system, excluding shell. This package is the union of the GNU fileutils, sh-utils, and textutils packages. Most of these tools offer extended functionality beyond that which is outlined in the POSIX standard.

GNU Diffutils is a package containing tools for finding the differences between files. The "diff" command is used to show how two files differ, while "cmp" shows the offsets and line numbers where they differ. "diff3" allows you to compare three files. Finally, "sdiff" offers an interactive means to merge two files.

Make is a program that is used to control the production of executables or other files from their source files. The process is controlled from a Makefile, in which the developer specifies how each file is generated from its source. It has powerful dependency resolution and the ability to determine when files have to be regenerated after their sources change. GNU make offers many powerful extensions over the standard utility.

This package provides a standalone shared library version of BFD, which is otherwise distributed and installed as part of the Binutils package release.

GNU Hello prints the message "Hello, world!" and then exits. It serves as an example of standard GNU coding practices. As such, it supports command-line arguments, multiple languages, and so on.
