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.
XZ Utils (previously LZMA Utils) is a set of free software command-line lossless data compressors, including the programs lzma and xz, for Unix-like operating systems and, from version 5.0 onwards, Microsoft Windows.
GNU ddrescue is a data recovery tool for disk drives, DVDs, CDs, and other digital storage media.It copies raw blocks of storage, such as disk sectors, from one device or file to another, while handling read errors in an intelligent manner to minimize data loss by scraping good sectors from partially read blocks.
For example, if the underlying file is a tar archive, this can allow extracting any undamaged files, even if other parts of the archive are damaged. As for the file format, special emphasis has been put on enabling integrity checks by means of an integrated 32-bit checksum for each compressed stream; [ 3 ] this is used in combination with the ...
Python tarfile module supports multiple tar formats, including ustar, pax and gnu; it can read but not create V7 format and the SunOS tar extended format; pax is the default format for creation of archives. [37] Available since 2003. [38] Additionally, most pax and cpio implementations can read and create multiple types of tar files.

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.
File copying is a fundamental operation for data storage. [citation needed] Most popular operating systems such as Windows, macOS and Linux as well as smartphone operating systems such as Android contain built-in file copying functions as well as command line (CLI) and graphical (GUI) interfaces to filing system copy and move functions. In some ...
