lzma LZMA uses lossless data compression along with various algorithms. Been in development since 1996, it was originally used by the 7-zip software for computers like the 7z format. The algorithm uses a dictionary-like compression scheme that has similarities to the algorithm created by Jacob and Abraham Lempel in 1977, the LZ77 algorithm. The LZMA algorithm boasts an increased ratio of compression and a 4-gigabyte variable dictionary sized compression. The LZMA decompression speed is the same as other compression software algorithms.
tar The .tar filename was originally designed to be used as a TApe ARchiver to store entire file systems and files as single files on tape storage medium. It was designed by AT&T in 1979. Today, the format more commonly refers to an archive or collation of multiple files into a single file with the .tar filename extension. The format is an open source file archive format commonly associated with the UNIX tar command however other data compression tools are capable of effectively compressing and/or decompressing files saved with the .tar file format. Doing so typically adds the compression filename extension to the archive file for example .tar.bz2.
