In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes. The name is derived from "tape archive", as it was originally developed to write data to sequential I/O devices with no file system of their own, such as devices that use magnetic tape.
The "tarball" format combines tar archives with a file-based compression scheme (usually gzip). Commonly used for source and binary distribution on Unix-like platforms, widely available elsewhere. Xarchiver supports the .tar.zst Archive/Compression format on Unix-like platforms.
pax is an archiving utility available for various operating systems and defined since 1995. [1] Rather than sort out the incompatible options that have crept up between tar and cpio, along with their implementations across various versions of Unix, the IEEE designed a new archive utility pax that could support various archive formats with useful options from both archivers.
libarchive provides command-line utilities called bsdtar and bsdcpio. [3] These are complete re-implementation based on libarchive. [9] [10] These are the default system tar and cpio on FreeBSD, NetBSD, macOS and Windows.
The operating systems the archivers can run on without emulation or compatibility layer. Ubuntu's own GUI Archive manager, for example, can open and create many archive formats (including Rar archives) even to the extent of splitting into parts and encryption and ability to be read by the native program.
NTBackup (also known as Windows Backup [1]: 20.1 and Backup Utility [1]: 20.4 ) is the first built-in backup utility of the Windows NT family. It was introduced with Windows NT 3.51 . NTBackup comprises a GUI ( wizard-style ) and a command-line utility to create, customize, and manage backups.
DarGUI for Linux and Windows, gdar for Linux. A text-mode browser/extractor: plugin for dar files in mc (Midnight Commander). A scheduler / command-line frontend known as SaraB allows the Towers of Hanoi, Grandfather-Father-Son, or any custom backup rotation strategy, and modifications are available for PAR file support. Extended versions known ...
A tar.gz is created by joining the files in tar and then compressing with gzip. In computing, solid compression is a method for data compression of multiple files, wherein all the uncompressed files are concatenated and treated as a single data block. Such an archive is called a solid archive.
